INTRODUCTIONThis owner's manual describes the
Fleet Power Inverter/Chargers from HeartInterface. These units perform three distinctfunctions:1. DC to AC power inverting.2. Automatic transfer switching between inverter power and incoming AC power.3. Automatic 3-Stage Battery charging plus manual battery equalizing.
4. AC to DC power converter.
• The inverters provide regulated 120 VoltAC power and crystal controlled frequencyat 60Hz from a deep cycle battery bank inspecified watts:
FP 1000-12................1000 wattsFP 2000-12................2000 wattsFP 2500-12................2500 watts
The output is a modified sinewave andis compatible with appliances, tools andother 120 VAC equipment. Momentarysurge power of three times the inverterrating is available for starting electric mo-tors. High efficiency insures the longestpossible battery life between recharges.
• The transfer switch allows the Fleet PowerInverter/Chargers to be connected to anexternal AC source and transfer the sourcethrough to the loads. When disconnected,the transfer switch allows automatic switch-ing back to the inverter.
Fleet Power Inverter/Chargers operateas self-contained backup power systems,just add batteries.
• Fleet Power battery chargers are electroni-cally controlled and rated:
FP 1000-12..................50 Amps DCFP 2000-12................100 Amps DCFP 2500-12................130 Amps DC
They are designed to rapidly and optimallyrecharge either wet* or gel* cell deep-cyclebatteries. Battery charging is accomplishedin 3 automatic stages: Bulk Charge, Accep-tance Charge and Float Charge. In addition,using the remote control, a manually-en-gaged Equalizing Charge cycle is possible.
With an external AC source connected,the Fleet Power charger also serves thefunctions of a AC to DC converter to supplyall of the DC loads which are connected tothe battery.
Simple, automatic operation is madepossible by the microprocessor in the FleetPower Inverter/Chargers. In most cases, theunit is left on and no attention or mainte-nance is required.

THINGS YOU SHOULD KNOW
The optional Fleet Power RemoteControl Panel provides a power switch,system status LEDs, DC Volts and DC AmpsLED bargraphs. On the back of the remoteis a set of dip switches which allow adjust-ment of the following:
• Manual Initiation of Equalize Charging• Ambient Battery Temperature• Battery Type• Charger Mode (Auto or Controlled)• Power Sharing
Circuit Breaker ProtectionFleet Power Inverter/Chargers are
circuit breaker protected.
The Fleet Power 1000 has a 12 AmpINV/CHG circuit breaker on the front of theunit that protects against sustained inverteroverloads over 1440 watts and the AC inputto the battery charger. The 15 Amp INPUTcircuit breaker on the unit protects theincoming AC circuit which is transferredthrough to the loads via the GFCI.
The Fleet Power 2000 has a 25 AmpINV/CHG circuit breaker that protectsagainst sustained inverter overloads over3000 watts and the AC input to the batterycharger. .
The Fleet Power 2500 has a 30 AmpOUTPUT circuit breaker on the unit thatprotects against sustained inverter over-loads over 3600 watts. The 30 Amp circuitbreaker protects the incoming AC leg whichfeeds the battery charger.
The 30 Amp TRANSFER circuit breaker
on the units protect the incoming AC circuitwhich is transferred through to the loadsconnected by the hardwire output.
The 15 Amp circuit breaker protects theGFCI outlet on the Fleet Power 1000 and2000 models. When a circuit breaker trips,the circuit breaker is reset by pushing thebutton back in.
Electronic ProtectionFast acting electronic circuits protect
the inverter from extreme overloads andshort circuits. Other protection includes alow and high battery cutoff and automaticshutdown if over temperature occurs. Thefault condition must be eliminated beforereset will occur. Example: remove over-load, recharge batteries or allow to cool.Reset by cycling the power switch OFF/ON.
Power SharingWhen connected to shorepower or
using a generator, the battery charger andtransfer functions are engaged. A uniquepower sharing feature automatically reducesthe AC consumption of the battery chargerallowing necessary AC power to the load.This prevents the circuit breaker from trip-ping. This feature can be adjusted usingthe remote control panel. This feature is setat the transfer rating of each unit by default.

Power SwitchThe Power Switch is located on the
front panel. This switch controls ON/OFFand RESET for the inverter. Expect a 3second delay when the power switch isturned ON before the unit is activated.
If the unit is connected to external ACpower, the battery charger and transferswitch will continue to function, regardlessof the position of the switch.
When external AC power is removedand the power switch is in the ON position,the inverter will automatically be ON. If theswitch is in the OFF position and externalAC power is removed, the inverter will beOFF.
Inverter overload protection, transferswitching, power sharing and batterycharger regulation will all function automati-cally.
If installed with the remote controlpanel, the power switch on the unit shouldbe left in the OFF position. Refer to Re-mote Control Panel, page 7.

DC Amps BargraphThese LEDs approximate DC input
current in inverter mode and DC outputcurrent in battery charger mode. Tworanges are used -- below 50 Amps eachsegment represents a 10 Amp increment,above 50 Amps each segment represents a20 Amp increment. Above 130 Amps, aflashing LED segment indicates the valuedisplayed plus 100 Amps (flashing 50 LEDis equal to 50 + 100 or 150 Amps DC).
If a shutdown occurs, the DC Ampsbargraph will stop indicating DC Amps andwill indicate the type of problem . Each LEDsegment indicates a different problem asdescribed in the troubleshooting section onpage 34.
Remote Power SwitchThe switch on the remote is used to
control the inverter and can also be used tocontrol the battery charger function. Whena remote control is used, the power switchon the inverter should be left in the OFFposition.
System Status LEDsThese 4 LEDs monitor the system as
described in the table on page 10.
DC Volts BargraphThese LEDs indicate battery voltage as
measured inside the unit. Each LED seg-ment indicates .5 Volts. If an overloadoccurs and the unit shuts down, the DC
An optional remote control panel isavailable which offers several features notfound on the unit. The remote control panelprovides LED bargraphs which show systemstatus, battery voltage, and DC Amps inboth inverter and charge modes. Thesebargraphs can also display dip switch posi-tions and shut down conditions.

REMOTE CONTROL PANEL
Dip SwitchesOn the back of the Fleet Power remote
control panel is a set of 8 dip switcheswhich are used to make several adjust-ments. On the switch block, each switch isnumbered . . .1 through 8 and the ON posi-tion is indicated. The switch settings can bechanged at any time, even while the unit isoperating. Following is a discussion ofeach adjustment. Refer to the table onpage 11 for dip switch programming.
SWITCH 1 - Manual Equalizing Cy-cling this switch ON for 1 second, then OFF,will initiate an equalizing charge cycle. Thebattery charger must be engaged beforecycling the switch. The dip switch mustalways be returned to the OFF position.If it is left ON, an equalizing charge cyclewill initiate every time the charger isengaged - this could cause battery dam-age.
The equalizing cycle is timed to last 8hours from the time the switch is cycled, atwhich point the charger resumes normalcharging in the float stage.
The battery LED blinks when equaliz-ing. See page 18 for a discussion of thetheory and procedure for battery equalizing.
SWITCH #2 & #3 - Battery Type Gel celland wet cell batteries have slightly differentcharge voltage requirements. Optimumbattery charging is temperature dependent.For these reasons, the dip switches allowfour different battery charger voltage setpoints, depending on battery type andambient temperature:
Cool Wet Cell < 80 degrees F.Warm Wet Cell > 80 degrees F.Cool Gel Cell < 80 degrees F.Warm Gel Cell > 80 degrees F.
Refer to the table on page 21 for thespecific voltages for each setting.
SWITCH #4 - Auto Charge With the switchin the OFF position, the remote panel ON/OFF switch only controls the inverter opera-tion. With the switch turned ON, it allowsthe power ON/OFF switch on the front of theremote to control the battery charger as wellas the inverter.
SWITCH #5 & #6 - Not used for adjust-ments.
SWITCH #7 & #8 - Power Sharing Theseswitches should be set to match the value ofthe circuit breaker which protects the incom-ing AC power. They may also limit theoutput current from the battery charger.

BATTERIES
BATTERY TYPESUse only deep-cycle batteries with your
Fleet Power Inverter/Charger. These fallinto two broad categories, wet cell and gelcell.
Wet Cell BatteriesTrue deep-cycle wet cell batteries are
characterized by relatively thick plates thatare alloyed with antimony.
Common marine/RV deep-cyclebatteries are acceptable. However, golfcart batteries have better performance andlife. They are 6 Volt batteries that must beused in series pairs. High quality marinedeep-cycle batteries offer good perfor-mance and are available in a wide varietyof sizes. Floor sweeper, fork lift or large 2Volt cells can also offer excellent perfor-mance, if their large size can be accommo-dated.
It should be noted that high antimonydeep-cycle batteries will give off gas as anatural result of charging and will experi-ence some water loss. It is very importantthat the electrolyte level be checkedfrequently and topped off with distilledwater when necessary. Never allow thetops of the plates to be exposed to air, ascontamination of the cell will result. Keep-ing the tops of batteries clean will reduceself-discharging. Always provide ventilationfor the battery storage compartment.
Do not use car batteries or enginestarting batteries of any kind with yourinverter/charger. Beware of any battery thatis rated in Cold Cranking Amps (CCA). Thisis a rating which applies only to enginestarting batteries. In general, most wet cellbatteries that are described as hybrid bat-teries, suitable for either engine starting ordeep-cycle applications, are a compromiseand will give limited life if deeply dis-charged.
Beware of 8-D starting batteries thatare commonly used for starting diesel en-gines. These batteries are not deep-cycle.
12
90-0115-0010/97 Fltman.pm65
BATTERIES
Beware of so-called maintenance-free batteries . These batteries have cal-cium alloyed with the lead and hold theliquid electrolyte in a sponge-like material.They are sealed and water cannot beadded. Do no confuse them with true gelcell batteries, they will not hold up to deepdischarging.
Gel Cell BatteriesGel cell batteries are lead-acid batter-
ies similar in many ways to the common wetcell battery, but differences in the chemistryand construction provide some uniquefeatures.
No Maintenance - There is no need toadd water and the tops of the batteries stayclean. Also, the batteries can be used inany position and may be used without abattery box.
Low Self-Discharging - Unlike wet cellbatteries, the gel cell will hold its charge formonths if left sitting with no load and nofloat charge. They can be stored without aconstant float charge and without fear offreezing.
Low Internal Resistance - The resultof low internal resistance is a higher batteryvoltage under load, which will result inbetter inverter performance on demandinghigh power loads. In addition, this allowsthe gel cell to accept a high rate of charge,a plus for rapid recharging.
The features of the gel cell batteriessolve many common problems. Cycle life ishigh, even under constant deep discharg-ing.
BATTERY INTERCONNECTIONIn most cases you will be using a bank
of two or more batteries with your inverter/charger. You may connect batteries to-gether in two configurations, series andparallel.
SeriesConnecting 2 batteries in series will
double the voltage of the battery bank. Forinstance, two 6 Volt batteries connected inseries will produce 12 Volts. The Amp-hourcapacity of the battery bank will be thesame as each individual battery. Example,two 6 Volt 220 Amp-hour batteries in serieswill produce on 12 Volt 220 Amp-hour bat-tery bank.

BATTERIES
Always use proper terminals for yourinterconnecting battery cables which areappropriate to handle the current.
Battery Bank Ratings and SizingDeep-cycle batteries are usually rated
in Amp-hours . The Amp-hour rating isbased on a 20 hour discharge cycle, there-fore, a 100 Amp-hour battery can deliver 5Amps for 20 hours. If the discharge rate isgreater than 5 Amps, the available Amp-hours are decreased. If the load is in-creased to 100 Amps, only about 45 Amp-hours will be available at this rate of dis-charge.
Another common rating is reservecapacity expressed in minutes. This isderived by placing a 25 Amp load on thebattery and measuring the time until thebattery voltage reaches 10.5 Volts.
Deep-cycle batteries can be dischargedabout 80% before permanent damageoccurs, though shallower cycling will resultin much longer battery life. 50% cycling isgenerally considered to be a good compro-mise between long battery life and a rea-sonably sized battery bank.
ParallelConnecting 2 batteries in parallel will
double the Amp-hour rating of the batterybank, while the voltage will be the same aseach individual battery. Example, two 12Volt 105 Amp-hour batteries in parallel willproduce one 12 Volt 210 Amp-hour batterybank.

Only similar batteries should beconnected together in one bank. Do notconnect old and new batteries together orwet and gel cell batteries together. In theabove drawing, the load is connected to thepositive terminal of the first battery and thenegative terminal of the last battery. Thispractice helps to balance the battery bankand is called cross connecting the batterybank.

BATTERIES
To achieve 50% cycling you shouldcalculate your Amp-hour consumptionbetween charging cycles and use a batterybank with twice that capacity.To calculate Amp-hour consumption firstlook at the rating plate on your AC appli-ance or tools. Each appliance or tool will berated in either AC Amps or AC watts or ACVA (Volts-Amps) apparent power. Use oneof the following formulas to calculate the DCAmp-hour draw for a 12 Volt system:
(AC Amps x 10) x 1.1 x hours ofoperation = DC Amp-hours
(AC watts/12) x 1.1 x hours of operation= DC Amp-hours
(AC VA/12) x 1.1 x hours of operation =DC Amp-hours
In all formulas, 1.1 is the factor forinverter efficiency.
Calculate the above for every ACappliance or tool you intend to use on yourinverter. This will give you the total numberof Amp-hours used between recharges.Size your battery bank using this number asa guideline. A good rule to follow is to sizethe battery bank about 2 times larger thanyour total Amp-hour load requirement. Planon recharging when 50% discharged.

Battery ChargingCompletely recharging wet cell deep-
cycle batteries requires the battery voltageto be raised beyond what is known as thegassing point. This is the voltage at whichthe battery begins to bubble and gas isgiven off. If charging stops short of thispoint, sulfate is left on the plates and dete-rioration of the battery begins. The gassingpoint will vary with battery temperature.
Gel cell batteries must not be chargedto their gassing point. In fact, high voltagecharging which gasses these batteries isharmful to them. They typically require alower bulk charge voltage and a higher floatvoltage. Consult the battery manufacturerfor specifications.
Conventional Battery ChargersMost conventional battery chargers are
single-stage constant voltage chargers.They must stop short of the gassing point orthey will overcharge the battery bank.Therefore, most 12 volt battery chargersbring the battery voltage up to about 13.8Volts.
BATTERY CHARGING
This presents two problems. First,since the battery voltage does not reach thegassing point, sulfate is left on the plates.Second, 13.8 volts is close enough to thegassing point that some gas will escape,and the wet cell battery will need to befrequently topped off with distilled water.
Conventional battery chargers alsosuffer from another inherent characteristic ofdesign, which is a tapering output. Whilethey will deliver their rated current into adeeply discharged battery, as the batterybecomes charged and the voltage rises, theoutput current of the charger tapers down.This taper continues as the battery ischarged, taking a very long time to reach anacceptable recharge.
Fleet Power Battery ChargersFleet Power battery chargers are de-
signed to overcome the limitations of con-ventional chargers by utilizing 3 distinctstages, each designed for optimal recharg-ing of both wet cell and gel cell deep-cyclebatteries.
16
90-0115-0010/97 Fltman.pm65
BATTERY CHARGING
NOTE: Fleet Power battery chargers are onwhenever there is AC power connected tothe charger input, regardless of the condi-tion of the On/Off switch. This feature canbe disabled by setting the dip switch #4(back of the remote) to "On" so that thecharger will also be controlled by the On/Offswitch.
Each time the battery charger is en-gaged, the 3 stages proceed automatically,resulting in an efficient, complete rechargeand safe battery maintenance. Use of theremote control provides the ability to peri-odically apply an 8-hour timed equalizingcharge.
The battery charger stages are:Stage 1 - Bulk Charge During the bulk
charge stage most of the charge current isdelivered to the battery bank. This phase isengaged as soon as the battery charger isactivated. Full rated charger current isdelivered to the battery bank until the bulkcharge voltage limit is reached. This resultsin a relatively rapid recharge.
Generally, a wet cell battery bankshould not be charged up to the gassingpoint at a rate which exceeds 25% of itscapacity. In other words, a 12 volt batterybank of 520 Amp-hours should not becharged at over 130 Amps.
17
90-0115-0010/97 Fltman.pm65
Gel cell batteries can accept a higherrate of charge. Consult the manufacturer forspecifications.
Stage 2 - Acceptance Charge Theacceptance stage immediately follows thebulk charge stage. During this stage thebattery voltage is held constant at the bulkcharge voltage limit and the current gradu-ally ramps down. During this stage thebattery is accepting its final amount ofcharge current and the last of the sulfate onthe plates is removed.
The acceptance stage lasts until thecharge current reaches about 6-7 Amps. Atimer will terminate the acceptance stage ifthis current level is not reached. This timeris set automatically when the dip switchesfor battery type are set. Maximum accep-tance time is 1 hour for wet cells and 3hours for gel cells. Gel cell acceptance timecan be increased because the battery is notgassing. Expect wet cell batteries to gassomewhat during acceptance, this is anecessary part of the charging process.
Stage 3 - Float Charge When theacceptance stage is terminated, eitherbecause the charge current ramped down to6-7 Amps or the timer engaged, batterycharger current will shut off. The unit moni-tors the battery voltage while it drifts downfrom the bulk charge voltage limit. When itreaches the float voltage set point, the floatcharge stage is engaged.
The float charge stage holds the batteryvoltage at a lower level, where it is safe forlong term battery maintenance. During thefloat charge stage, the full output current ofthe battery charger is available to operateany DC appliances that may be on thesystem, while constantly maintaining thefloat charge voltage.
The battery charger remains in the floatcharge stage indefinitely until the charger isdisconnected from incoming AC power.
Stage 4 - Equalizing Charge This isthe only battery charger stage which is notengaged automatically. It must be manuallyinitiated each time it is necessary to equal-ize using a dip switch on the back of theremote control. Applying an equalizingcharge is not possible without the use of aremote.
Periodic equalizing is recommended bymost wet cell deep-cycle battery manufac-turers. There are no firm rules for how oftenan equalizing charge should be applied, butonce a month is a good rule of thumb forbatteries which are regularly cycled, lessoften for systems in only occasional use.
The equalizing charge is a timed, 8-hour cycle. If desired, it can be ended byinterrupting the AC power to the charger atany time during the cycle. Equalizingshould be engaged after the batteries havebeen fully charged by a normal battery

charging cycle. The battery voltage willincrease to 16.3 using the cool temperaturewet cell setting. This will cause the batterybank to gas profusely and will accomplishthe following:
1. Removal of residual sulfate. Each timea battery is cycled (discharged and re-charged), a small amount of sulfate is left onthe plates. Over time, this gradual build-upof sulfate will compromise the performanceof the battery. By applying an equalizingcharge, the sulfate is returned back to theelectrolyte, raising the specific gravity andfully exposing the active material of theplates.
2. Bring all cells to the same potential.All lead-acid batteries are made up of indi-vidual 2 Volt cells. As the battery bank iscycled, slight differences in the cells resultin different cell voltages, affecting the over-all charge effectiveness. Equalizing bringsall cells up to the same voltage and theelectrolyte in each cell to the same specificgravity.
3. Mixing up of the electrolyte. Electro-lyte in battery cells tend to separate intolayers of acid and water. The vigorousboiling action of the battery during equaliz-ing serves to physically mix the electrolyte.
BATTERY CHARGING
Equalizing is not required on gel cellbatteries. You will note that if the dipswitches are set in one of the two gel cellpositions, the equalizing charge voltage isthe same as the bulk charge voltage, there-fore, equalizing is equivalent to an 8-houracceptance stage and is not harmful.
To limit the DC current during equaliz-ing to less than 15 Amps, turn on dipswitches 7 and 8 before starting the equal-ize charge. Do not operate AC loads thatare on the output of the inverter/chargerwhen equalizing.
Charging Over-Discharged BatteriesCharging into a battery bank with a
terminal voltage of less than 8 Volts pre-sents a special problem for the unit. If thissituation arises, the unit will attempt tocharge for 1 minute. If the inverter sensesexcessive ripple voltage, it will shut down toprotect itself.
To successfully charge an over-discharged battery, you must remove asmuch DC load as possible. Set dipswitches 7 and 8 to the ON position to limitthe amount of charge current and the result-ing ripple voltage. After the battery voltagehas reached 10 Volts, these switches canbe set to their previous positions.
19
90-0115-0010/97 Fltman.pm65
BATTERY CHARGING
1. Do not equalize gel cell batterieswith the remote programmed for wetcells.2. Always monitor the equalizecharge. Provide proper ventilation forbattery fumes. Do not allow any sparksduring equalizing. If one or more cellsbegin to overflow, terminate the equalizecharge.
3. Check and top off the battery elec-trolyte both before and after theequalizing charge. Do not expose thebattery plates to air. Leave the batterycaps on while equalizing.
4. Remove all loads from the DC sys-tem before equalizing. Some DC loadsmay not tolerate the high charge voltage.
5. Do not leave the equalize dipswitch in the ON position. It must becycled OFF and left in the OFF position.If left ON, the unit will engage the equal-izing cycle every time the battery chargeris engaged.
WARNINGSNote: If a continuous DC load in ex-
cess of the charge rate is placed on thebattery bank, eventually the battery voltagewill drop below 8 Volts and the batterycharger will shut off. This load must besignificantly reduced and the power to thecharger cycled to resume charging.
Blinking of the battery LED on theremote control while charging is a warningthat an over-discharge is imminent and thatthe DC load should be reduced.

INSTALLATION
Key Installation Points
The Power Switch must be turned OFFbefore you begin.
1. Observe proper polarity whenconnecting batteries. Reverse DC polaritywill result in damage to the unit and will voidthe warranty. Use care when making theDC connections.
2. Do not back-feed the AC output ofthe inverter with incoming AC power. Aback-feed occurs when AC power fromshore power or generator is connected tothe output of the inverter. This will damagethe inverter and void the warranty. Remem-ber that incoming AC must be fed only tothe AC input and never to the AC output.Always check for AC voltage before con-necting wires to the AC output. Do NOTturn the inverter ON until all AC connectionshave been made. Back-feeding the invertervoids the warranty.
3. Do not connect the AC input to theAC output. In effect, this would be plug-ging the battery charger into the inverter.This could occur if the unit is connected tothe entire leg of a circuit breaker panel, thena circuit breaker on that leg is used to feedthe battery charger. This will cause the unitto oscillate ON and OFF when the unit is ininverter mode.
4. Always use proper wire and con-nectors. The proper battery cable size iscritical because considerable amperageflows in the DC circuit. Fusing the positive
DC cable is required. The AC wire size isdependant on potential current in the circuit.Consult the NEC (National Electric Code)for proper wire gauge.
5. Keep the inverter/charger out ofthe elements and out of direct contactwith water or spray. Remember that theunit is a piece of electronic equipment andtreat it accordingly.
6. Mount the unit as close to thebatteries as possible but not in the pres-ence of flammable fumes or in an enclosedbattery compartment.
7. The connectors for the remotecontrol and the chassis ground bondinglug, as well as for the AC wires, are lo-cated on the bottom of the unit. Be sureto make these connections before boltingthe unit down.
8. You may mount the unit horizon-tally (on a shelf) or vertically (on a wall orbulkhead). If mounted vertically, you mustorient the unit so the switch and the circuitbreakers are facing up and the fan andbattery cables are facing down.
9. Allow several inches of clearancearound the unit and allow for a supply offresh air to the cooling fan. Do not blockany of the vents or louvers. The fan pullsair from outside the unit. It blows air acrossthe internal components, particularly thetransformer and heat sinks, then out theside vents.

INSTALLATION
15. If multiple battery banks are to becharged, a battery selector switch can beinstalled, allowing the banks to be chargedeither individually or simultaneously. Asolenoid can also be used.
10. If installing in a system which in-cludes an existing battery charger or con-verter, make sure these do not operatefrom the inverter output AC power. Thissets up a power loop which, due to ineffi-ciencies, will quickly drain the batteries.
11. Make sure all wiring conforms tolocal and national electrical codes. If indoubt, consult with a qualified electrician.
12. Keep the overall length of eachbattery cable less than 10 feet. If needed,attach short extension cables. Do not useframe ground or a ground bonding systemas a current carrying conductor. Run thenegative cable directly to the battery bank.If the positive and negative cables runparallel to each other, twist the cablestogether. This will minimize the adverseeffects of inductance.
13. To meet electrical codes , a fusemust be installed in the positive batterycable within 18 inches of the battery post.This fuse is intended to protect the batteryand cables against a dead short circuit.The inverter is protected internally and willnot blow a properly sized fuse.
14. DC wiring is generally very simple,the positive and negative cables from theinverter/charger are connected to the houseor auxiliary battery. In the case of multiplebatteries the interconnecting jumper cablesmust be of the same AWG as those sup-plied with the inverter/charger.
GroundingFor safety purposes, the chassis of
the inverter/charger must be connectedto your AC ground system . The chassisground bonding lug is located on the bottomof the unit. This connector can accept twowires, the first is used to connect the unit toAC ground, the second can be used toconnect other AC equipment to ground.
Use bare copper insulated wire, solid orstranded. Strip one end and use a screw-driver to secure it to the chassis groundbonding lug. This wire will connect to theground in your AC electrical system, typi-cally the vehicle chassis. Make sure theconnection is clean and tight.
Do not mount the unit in an enclosedbattery compartment. Take precautionsto keep road dirt and spray off the unit.
WARNING

90-0115-0010/97 Fltman.pm65
This procedure will connect the chassisof your unit to AC ground. In addition, theAC input and AC output green wires areconnected to chassis ground. It is importantto connect these wires to the AC ground busin the circuit breaker panel.
Note: The battery cables are not con-nected to ground or the chassis of the unit.
Neutral BondingFor safety purposes, the Fleet Power
inverter/charger unit internally bonds the ACoutput neutral to the AC ground when theunit is OFF or in the inverter mode. Whenincoming AC power is applied and thetransfer switch is engaged, the internalneutral-to- ground bond is automaticallylifted.
This means that when the vehicle isconnected to shore power, the groundingsystem is connected to the shore powerground, where neutral and earth ground arebonded together. This technique insuressafety in all conditions and conforms to therequirements of the NEC.
AC WiringThe AC wires route through the holes in
the bottom of the unit. Use a screwdriver toremove the screws which secure the ACwiring compartment cover plate. Inside, thecompartment is divided into 2 sections, onelabeled AC Input , the other labeled AC
Output . Each side contains 3 pigtails:black, white and green. Six wire nut con-nectors are also provided.
Black Hot or LineWhite NeutralGreen Ground
Conventional metal strain reliefs areprovided. These can be replaced by plasticstrain reliefs for additional corrosion resis-tance or 3/4 inch conduit fittings if the wiringwill be routed through the conduit.
Use proper wire sizes according to theNEC.
AC Input (Fleet Power 1000 and FleetPower 2000): Feed the 3 conductor ACinput wire through the strain relief and intothe AC input compartment. You shouldhave 6 inches of individually insulatedblack, white and green wire. Strip 1/2 inchof insulation off each conductor and connectto the pigtails: black to black, white to whiteand green to green.
AC Input (Fleet Power 2500): Thereare 2 options for configuring the AC input tothe Fleet Power 2500.
Dual Inputs: The internal batterycharger may be fed separately from thetransfer input which feeds the AC loads. Inthis case, connect one 30 Amp feed to thecharger pigtails and another 30 Amp feed tothe transfer switch input.
Connecting the feeds in this way bal-ances the AC loads when 2 legs of incomingAC power are available. These two feedscan be in or out of phase. Transfer will only

If you are not connecting the hardwireoutput wires (Fleet Power 2000 only), makecertain they can not cause a short circuit tothe wiring compartment. Tug firmly on eachconnection to make sure they are secure.Check these connections first if the unit isnot operating properly.
Carefully tuck the wires into the ACwiring compartment. Replace cover plate.
Ground Fault Circuit InterruptersIn order to conform to the NEC, certain
branch circuits must be equipped with aGround Fault Circuit Interrupter (GFCI).Please consult the code or a qualifiedelectrician for details. Any such branchcircuit must be protected by a circuitbreaker consistent with the GFCI rating.Underwriters Laboratories has tested thefollowing GFCI, and its use is recom-mended. Receptacle Type:
Pass & SeymourCatalog Number 1591-RWRated: 15 Amps at 120 Volts AC
Fleet Power 1000 and 2000 inverter/chargers provide an integral GFCI outletwhich is protected by a circuit breaker. ThisGFCI outlet does not protect the hardwireAC output. The hardwire AC output isprotected by a non-GFCI circuit breaker onthe Fleet Power 2000 only. The first outletfrom the hardwire output should be GFCIprotected to comply with applicable codesand standards.
The GFCI Receptacle is designed toprotect from line-to-ground shock hazardswhich could occur from defective power

15, 20 or 30 Amp Shore PowerInverter Runs Entire Panel
In this system, the shore power isthe only external AC power sourceavailable. The entire circuit breakerpanel is connected to the output ofthe inverter/charger. Take thesethings into consideration are:
1. When you unplug from shorepower, be sure to turn OFF any appli-ances or tools that you do not want on theinverter. This will prevent overloading theinverter or a rapid discharge of the batterybank.
2. Power Sharing should be set forthe same value as the input shore powerbreaker.
3. If a converter or battery chargerwas originally wired into the system, itshould be disconnected. Do not allow aconverter/charger to operate on the in-verter power. This type of power loop willonly discharge the batteries.

DC WIRING OPTIONS
DC Wiring #1 - Two Battery* SystemUsing Manual Battery Switch
This system is simple and effective,providing the user with the ability to choosebetween either battery for inverter use orcharging.
When charging, the battery switch istypically left in the "All" or "Both" position sothat both batteries are charged. Whenusing the inverter, the inverter batteryshould be selected with the battery switch.
The inverter/charger's negative batterycable should be connected directly to thebattery that will normally supply the inverter.A fuse should be installed in the positivecable within 18 inches of the battery. If thecables to the switch exceed 18 inches, eachcable will require a fuse.
DC Wiring #2 - Two Battery* SystemUsing an Isolator for Charging bothBatteries
This allows charging of both batteriesfrom an alternator, but the inverter can onlydraw power from the auxiliary battery. Thisprevents accidental discharge of the enginebattery by the inverter. A paralleling sole-noid can be used in place of the isolator.

TROUBLESHOOTING
1. Digital clocks either employ an internal timebase or derive their time base from the incomingAC waveform. The frequency is usually wellregulated at 60 Hz. The clock either counts thenumber of peaks in the waveform or the numberof times the waveform crosses zero volts. Thecircuitry to count the zero crossing events is morepopular. The longer zero cross time of theinverter's modified sinewave may cause doubleclocking, resulting in a faster clock.

Problem Things to Check
No InverterOutput
1. Battery voltage under load.2. Battery connections and DC fuse.3. Circuit breaker on front panel.4. Thermal condition, high powered loads orinadequate ventilation may cause overheating.5. Overloads or short circuit, check for excessiveloads or bad wiring connections.6. Reset button oin GFCI outlet.
Low InverterOutput Voltage
Confirm that your volt meter is a true RMS meter.Standard volt meters will not accurately read thewaveform of the inverter and may read anywherefrom 90 to 120 volts. If a true RMS meter is notavailable, check the brightness of an incandescentlight bulb - if it appears normal, the output voltage isproperly regulated.
Little or NoOutput from
BatteryCharger
1. Wiring connections - check both the AC and DCconnections.2. AC input voltage - low voltage input will result inlow DC output current. Expect reduced chargeroutput from generators under 3,500 watts.3. AC reverse polarity - check for voltage betweenthe incoming white and green wires. If 120 volts ismeasured, this is reverse polarity.
MicrowaveOven Cooking
Slow
1. Microwave ovens will normally cook slow oninverters due to a slightly low peak AC voltage. 2.Cooking speed will be determined by batteryvoltage. Low voltage results in increased cookingtime. Support the battery bank with an alternator orother charging source for quicker cooking.
