TOSHIBA

1.0 Inspection/Storage1.1 Inspection of the new UPS equipment

Upon receipt of the UPS, a careful inspection for shipping damage should be made.After Uncrating:

1) Check the unit for loose, broken, bent or otherwise damaged parts. If damagehas occurred during shipment, keep all original crating and packing materials

for return to shipping agent. Warranty will not apply to units which are damaged

during shipment.

2) Check to see that the rated capacity and the model number specified on thenameplate conform to the order specifications.

1.2 Storage of UPS equipment.

If the UPS equipment is to be subject to long or short term storage the followingguidelines should be used.Avoid:

1) Storage in sites subject to extreme changes in temperature or high humidity.

2) Storage in sites subject to exposure of high levels of dust or metal particles

3) Storage on inclined floor surfaces or in sites subject to excessive vibration.

Before storing:

1) Charge the units batteries.

2) Place the UPS ON/OFF switch in the OFF position.

Storing:

1) Store within a temperature range of -20 to 40 deg C (-4 to 104 deg F).

2) For best results, store the UPS in the original shipping container and place on awood or metal pallet.

3) The optimum storage temperature is 21 deg C (70 deg F). Higher ambienttemperatures cause UPS batteries to need recharging more frequently.

After storing:

1) If stored in an ambient temperature under 20 deg C (68 deg F); recharge thebatteries every 9 months.

2) If stored in an ambient temperature of 20 to 30 deg C (68 to 86 deg F);recharge the batteries every 6 months.

3) If stored in an ambient temperature of 30 to 40 deg C (86 to 104 deg F);

recharge the batteries every 3 months.

2.0 Precautions2.1 Installation Precautions

1) Install the unit in a well ventilated location; allow at least 10 cm (4 inches) onall sides for air ventilation and for maintenance.

2) Install the unit in a stable, level, and upright position which is free of vibration.

3) Install the unit in an environment where the ambient temperature isbetween 0 to 40 deg C (32 to 104 deg F).

4) Do not install the UPS in areas that are subject to high humidity.

5) Do not allow direct sunlight to shine on the unit.

6) Do not install the UPS in areas which are subject to contamination such ashigh levels of airborne dust, metal particles, or inflammable gas.

7) Avoid installation near sources of electrical noise and always make sure that

the unit ground is intact to prevent electrical shock and to help reduceelectrical noise.

8) Do not install where water or any foreign object may get inside the UPS.

9) This UPS generates and can radiate radio-frequency energy during operation.Although RFI noise filters are installed inside the unit there is no guarantee

that the UPS will not influence some sensitive devices which are operatingclose by. If such interference is experienced, the UPS should be installed farther

away from the effected equipment and/or powered from a different source than

that of the affected equipment.

2.2 Prestart Precautions1) Before connecting the UPS to a power source; move the ON/OFF switch, on

the front panel (See Section 8.1), to the OFF position.

2.3 Operating Precautions

1) The UPS should not be powered up until the entire operation manual hasbeen reviewed.

2) The input power source voltage must be within +10% to -30% of the rated input

voltage. The input frequency must be within the rated input frequency range.Voltages and frequencies outside of the permissible tolerance range may causeinternal protection devices to activate.

3) The UPS should not be used with a load whose rated input is greater than the

rated UPS output.

4) Do not use the UPS to provide power to motors that require high starting currentor a long starting time such as vacuum cleaners and machine tools.

5) Do not insert metal objects or combustible materials in the unit's ventilation slots.

6) Do not place, hang, or paste any objects on the top or on the exterior surfacesof the UPS.

3.0 Product Description3.1 Theory of Operation

An uninterruptible power supply is a system that is installed between the commercialpower and the load equipment. It is used during short-term blackouts or brownouts. The

UPS provides steady ac output power during these commercial power interruptions.This power is provided for a long enough time so that the load can be shutdown in an

orderly fashion. This prevents loss of data and possible damage to both hardware and

software.

During normal operation the UPS uses commercial ac power. In addition, it also takesin all of the high voltage spikes and transients caused by switching and faults, and all

of the common mode and normal mode noise which is associated with commercial acpower. The UPS converts it all to flat dc power. From this dc power, the UPS charges

its batteries and generates its own extremely high quality ac waveform output. Theresult of this process is maximum power conditioning.

If the ac power supplied to the UPS drops below a specified voltage level, the unit's

batteries automatically begin supplying power instead of receiving it. This insures thatthe loads connected to the UPS continue to receive power with no interruption. Whenac input power becomes available again, operation returns to normal. The unit's

batteries begin to recharge so they will be ready for the next power interruption.

3.2 Application and Use

Toshiba's 1400 Series of on-line uninterruptible power supply (UPS) systems provide

continuous computer-grade ac power in a compact, high performance, and energyefficient unit. The UPS unit assures safe and reliable operation of critical officeequipment. This can range from word processors and personal computers to mini-

computers and local area networks. All units feature an audible alarm which sounds if

the battery voltage drops below standard during use. This is an additional aid to helpin retaining the valuable office data banks. All units allow for computer interfacing and

and an external battery pack option (see specifications).

3.3 Power BackupWhen an electrical power failure occurs, the UPS unit's internal maintenance-free

batteries automatically supply back-up power to the load without interruption. Forexample, when used to support a computer, the UPS back-up assures enoughadditional time to complete the activity and store data. This allows an orderly shutdown

after a power failure has occurred.

3.4 Power Conditioning

When commercial power is present, the UPS supplies conditioned power to the load

while maintaining its batteries in a charged condition. The UPS protects against thenormal everyday problems associated with heavy use of raw commercial ac power,including power sags, surges, signal interference, and spikes. This protection keeps

power-line problems from reaching the loads where they can cause equipment to

operate erratically, hard-disk crashes, or cause damage to hardware and software.

Both of the above illustrations show circuit power flow in the ac input mode.

The UPS unit's rectifier, included in a boost chopper circuit, converts ac inputpower to dc power. This dc power runs the unit's transistor inverter and chargesthe batteries. The boost chopper circuit maintains a constant voltage, with

current limiting, for charging the batteries and assures proper sine waveformgeneration for the output current. The unit's batteries are maintained in a

constantly charged state when the UPS is in the normal operation mode.

Power flow in battery backup mode for 1500 and 2000 VA Models

The above illustrations show power flow during the battery backup mode.

When commercial ac power failures occur, the UPS's batteries instantly beginsupplying dc voltage to the UPS's main inverter circuit. This circuit changes

(inverts) the dc power into ac power. The ac power is available at the unit'soutput receptacles. This back-up process will continue until the UPS's battery

voltage drops below a specific minimum level. When this occurs, the batterieswill stop supplying power to the load. This minimum level is the rated minimum

voltage (Vmin). The rated battery voltage chart on page 5-6 (See Section 5.4for battery backup time) shows (Vmin).

(Plus Series)

If the UPS unit is overloaded or develops an internal fault, the power flow is

automatically switched from the unit's main circuit to the bypass circuit mode.Power flow through the bypass is shown in the above illustrations. This change-

over occurs automatically in approximately 4 milliseconds. The switching periodis not long enough to cause interruptions to occur in most UPS equipment loads.

After repairing the cause of the inverter shutdown, the energy flow must betransferred manually from the UPS's bypass circuit back to the inverter circuit.

This is done by toggling the ON/OFF switch (on the unit's front panel) first toOFF and then back to ON. This action resets (clears) the fault.

Notes:

1) The UPS's RECT/CHOPPER and INVERTER, although separate electricalcircuits, are physically located on the same heat sink. This is applicable to all

models.

2) The two UPS rear panel output receptacles are supplied from the UPS invertersection through separate 15A output fuses (applies to the 1500 and 2000 VAmodel only). Thus, an overload on one of the receptacle sets can cause a loss

of power to it while the other receptacle set remains active. If all of the UPSindicator lights appear normal and power is not available at one of the receptacle

sets, check the associated output fuse.

1.) AC LINE: This green LED lights when normal ac input power is being supplied tothe UPS unit.

2.) INVERTER: This green LED lights when the inverter output voltage is normal.

3.) FAULT: This red LED lights when an overcurrent, overvoltage, overload, or

overheating problem is detected. Operation of the unit's inverter is inhibited untilthe fault is corrected and the system is reset. Refer to Section 5.2 "SystemProtection Features" for details.

The UPS unit's batteries provide about 10 minutes of back-up time for the 500through 1200 VA capacity units and about 8 minutes of back-up time for the

1500 through 2000 VA capacity units. These times are valid when the unit isoperating under full load. When the units are operating at half load, the batteries

can power the load equipment about 3 times longer. The exact length of thesetimes will depend on the UPS model used, condition of the batteries, amount of

load, temperature and other variables. See battery backup time in the standardspecifications Sections 4.1 and 4.2.

The recharge process usually consists of three periods. During the first period, the

current is maintained at approximately 0.4 amperes. In the second period, the constant-voltage control starts and the current gradually decreases as the batteries continue to

charge. In the third period, a slight current flows into the batteries to keep them fullycharged. After a complete discharge, a full recharge usually requires 24 hours (90%

recharge in 8 hours) for the 500 through 750 VA models and 30 hours (90% recharge in8 hours) for the 800 through 2000 VA models.

The chart depicted below shows the rated maximum and minimum battery voltages,and the charge current for each of the sizes.

7.0 Preventive Maintenance/Parts Replacement7.1 Preventive Maintenance

Toshiba's 1400 Series of uninterruptible power systems have been designed to provide

years of trouble-free operation requiring a minimum of preventive maintenance.

The best preventive measure that the UPS user can take is to keep the area around theunit, particularly the air inlet vents, clean and free of moisture and dust accumulations.

If the atmosphere of the installation site is very dusty, use a vacuum cleaner toperiodically remove dust accumulations from the system.

7.2 Parts ReplacementThe following list shows recommended intervals for periodic replacement of certain

UPS parts.

1) Batteries: In order to maintain system reliability, the UPS unit's batteries

should be replaced once every 3 to 5 years. To ensure reliable operation, allof the batteries should be replaced at the same time.

2) Aluminum electrolytic capacitors: Replace once every 5 years.

3) Fuses: Replace once every 7 years (see output fuse rating chart below).

4) Cooling fan: Replace once every 3 years.

7.3 Input/Output Fuse Rating ChartThe following chart shows the recommended fuses for all UPS sizes.
