Section 1 — General InformationATS “HS” Type Transfer Switch

1.1 INTRODUCTIONThis manual has been prepared especially for the purpose of familiarizing personnel with the design, application, installation, operation and servicing of the applicable equipment. Read the manual carefully and comply with all instructions. This will help to prevent accidents or damage to equipment that might otherwise be caused by carelessness, incorrect appli-cation, or improper procedures.

Every effort has been expended to make sure that the contents of this manual are both accurate and cur-rent. The manufacturer, however, reserves the right to change, alter or otherwise improve the product at any time without prior notice.

1.2 EQUIPMENT DESCRIPTIONThe automatic transfer switch is used for transfer-ring electrical load from a UTILITY (NORMAL) power source to an EMERGENCY (STANDBY) power source. Such a transfer of electrical loads occurs automati-cally when the UTILITY power source has failed or is substantially reduced and the EMERGENCY source voltage and frequency have reached an acceptable level. The transfer switch prevents electrical feedback between two different power sources (such as the UTILITY and EMERGENCY sources) and, for that reason, codes require it in all standby electric system installations.

The transfer switch consists of a transfer mecha-nism, service disconnect circuit breaker, a relay control, fuses, and a terminal strip for connection of sensing wires.

This transfer switch is suitable for use as service entrance equipment.

1.2.1 TRANSFER SWITCH MECHANISMThese switches (Figure 1.1) are used with a single-phase system, when the single-phase NEUTRAL line is to be connected to a Neutral Lug and is not to be switched.

Solderless, screw-type terminal lugs are standard.

Switch Wire Conductor Tightening Rating Range Torque 100A #14-1/0 AWG 50 in-lbs. 200A #6-250 MCM 275 in-lbs.

This transfer switch is suitable for control of motors, electric discharge lamps, tungsten filament and elec-tric heating equipment where the sum of motor full load ampere ratings and the ampere ratings of other loads do not exceed the ampere rating of the switch and the tungsten load does not exceed 30 percent of the switch rating.

When requesting information or ordering parts for this equipment, make sure to include all information from the DATA DECAL.

Record the Model and Serial numbers in the space provided below for future reference.

1.4 TRANSFER SWITCH ENCLOSUREThe standard switch enclosure is a National Electrical Manufacturer’s Association (NEMA) 3R type. NEMA 3R type enclosures primarily provide a degree of protection against falling rain and sleet and is undamaged by the formation of ice on the enclosure.

1.5 SAFE USE OF TRANSFER SWITCHBefore installing, operating or servicing this equip-ment, read the SAFETY RULES (inside front cover) carefully. Comply strictly with all SAFETY RULES to prevent accidents and/or damage to the equipment. The manufacturer recommends that a copy of the SAFETY RULES are posted near the transfer switch. Also, be sure to read all instructions and information found on tags, labels and decals affixed to the equip-ment.

Two publications that outline the safe use of transfer switches are the following:

• NFPA 70; National Electrical Code• UL 1008, STANDARD FOR SAFETY-AUTOMATIC

TRANSFER SWITCHES

2.1 INTRODUCTION TO INSTALLATIONThis equipment has been wired and tested at the factory. Installing the switch includes the following procedures:

• Mounting the enclosure.• Connecting power source and load leads.• Connecting the generator sensing and transfer

relay circuits.• Connecting any auxiliary contact (if needed)• Testing functions.

2.2 UNPACKINGCarefully unpack the transfer switch. Inspect closely for any damage that might have occurred during ship-ment. The purchaser must file with the carrier any claims for loss or damage incurred while in transit.

Check that all packing material is completely removed from the switch prior to installation.

2.3 MOUNTINGMounting dimensions for the transfer switch enclo-sure are in this manual. Enclosures are typically wall-mounted. See “Installation Diagram”, Section 5.

Handle transfer switches carefully when install-ing. Do not drop the switch. Protect the switch against impact at all times, and against construc-tion grit and metal chips. Never install a transfer switch that has been damaged.

This transfer switch is mounted in a NEMA 3R enclo-sure. It can be mounted outside or inside and should be based on the layout of installation, convenience and proximity to the utility supply and load center.

Install the transfer switch as close as possible to the electrical loads that are to be connected to it. Mount the switch vertically to a rigid supporting structure. To prevent switch distortion, level all mounting points. If necessary, use washers behind mounting holes to level the unit.

2.4 CONNECTING POWER SOURCE AND LOAD LINES

DANGER

Make sure to turn OFF both the UTILITY (NORMAL) and EMERGENCY ( STANDBY) power supplies before trying to connect power source and load lines to the transfer switch. Supply voltages are extremely high and dangerous. Contact with such high voltage power sup-ply lines causes extremely hazardous, possibly lethal, electrical shock.

Wiring diagrams and electrical schematics are pro-vided in this manual.

Two suggested installation methods are shown. One for new installations and/or retrofit and one for ret-rofit.

NOTE:

All installations must comply with national, state and local codes. It is the responsibility of the installer to perform an installation that will pass the final electrical inspection.

The utility supply connection is made at the circuit breaker terminals. The generator supply and custom-er load connections are made at the transfer switch mechanism, inside the switch enclosure.

Section 3 — OperationATS “HS” Type Transfer Switch

Conductor sizes must be adequate to handle the maximum current to which they will be subjected to, based on the 75°C column of tables, charts, etc. used to size conductors. The installation must comply fully with all applicable codes, standards and regulations.

Before connecting wiring cables to terminals, remove any surface oxides from the cable ends with a wire brush. All power cables must enter the enclosure through the knockouts. If not using the knockouts, entry must be at or below knockouts. If ALUMINUM conductors are used, apply corrosion inhibitor to conductors. Tighten terminal lugs to the torque values as noted in Section 1.2.2, and on the decal located on the inside of the door. After tightening ter-minal lugs, carefully wipe away any excess corrosion inhibitor.

Use a torque wrench to tighten the conduc-tors, being sure not to overtighten, or damage to the switch base could occur. If not tightened enough, a loose connection would result, caus-ing excess heat which could damage the switch base.

Connect power source load conductors to clearly marked transfer mechanism terminal lugs as fol-lows

1. Connect UTILITY (NORMAL) power source cables to circuit breaker.

2. Connect EMERGENCY (STANDBY) source power cables to transfer switch terminals E1, E2.

3. Connect customer LOAD leads to switch termi-nals T1, T2.

Conductors must be properly supported, of approved insulative qualities, protected by approved conduit, and of the correct wire gauge size in accordance with applicable codes.

Be sure to maintain proper electrical clearance between live metal parts and grounded metal. Allow at least 1/2 inch for 100-400 amp circuits.

2.5 CONNECTING START CIRCUITWIRES

Control system interconnections consist of N1 and N2, T1 and T2, and leads 23 and 194. Control system interconnection leads must be run in a conduit that is separate from the AC power lead. Recommended wire gauge sizes for this wiring depends on the length of the wire, as recommended below:

MAXIMUM WIRE LENGTH RECOMMENDED WIRE SIZE 460 feet (140m) No. 18 AWG. 461 to 730 feet (223m) No. 16 AWG. 731 to 1,160 feet (354m) No. 14 AWG. 1,160 to 1,850 feet (565m) No. 12 AWG.

NOTE:

When this ATS is used with an air-cooled genera-tor, the LOAD 1 and LOAD 2 wires are not used.

3.1 FUNCTIONAL TESTS ANDADJUSTMENTS

Following transfer switch installation and inter-connection, inspect the entire installation care-fully. A competent, qualified electrician should inspect it. The installation should comply strictly with all applicable codes, standards, and regula-tions. When absolutely certain the installation is proper and correct, complete a functional test of the system.

Perform functional tests in the exact order pre-sented in this manual, or damage could be done to the switch.

IMPORTANT: Before proceeding with functional tests, read and make sure all instructions and information in this section are understood. Also read the infor-mation and instructions of labels and decals affixed to the switch. Note any options or accessories that might be installed and review their operation.

3.2 MANUAL OPERATIONDANGER

Do NOT manually transfer under load. Disconnect transfer switch from all power sourc-es by approved means, such as the main circuit breaker(s).

A manual HANDLE is shipped with the transfer switch. Manual operation must be checked BEFORE the transfer switch is operated electrically. To check manual operation, proceed as follows:

1. Turn the generator’s AUTO/OFF/MANUAL switch to OFF.

2. Turn OFF both UTILITY (service disconnect cir-cuit breaker) and EMERGENCY (generator main line to circuit breaker) power supplies to the transfer switch.

3. Turn the GENERATOR DISCONNECT SWITCH to the OFF position.

4. Note position of transfer mechanism main con-tacts by observing the moveable contact carrier arm. This can be viewed through the long narrow slot in the inside cover of the ATS. The top of the moveable contact carrier arm is yellow to be eas-ily identified.

• Manual operation handle in the UP position - LOAD terminals (T1, T2) are connected to UTIL-ITY terminals (N1, N2).

5

• Manual operation handle in the DOWN posi-tion - LOAD terminals (T1, T2) are connected to EMERGENCY terminals (E1, E2).

Do not use excessive force when operating the transfer switch manually or damage could be done to the manual handle.

3.2.1 CLOSE TO NORMAL SOURCE SIDEBefore proceeding, verify the position of the switch by observing the position of manual operation handle in Figure 3.1. If the handle is UP, the contacts are closed in the NORMAL (UTILITY) position, no further action is required. If the handle is DOWN, proceed with Step 1.

Step 1: With the handle inserted into the moveable contact carrier arm, move handle UP. Be sure to hold on to the handle as it will move quickly after the center of travel.

Step 2: Remove manual operating handle from move-able contact carrier arm. Return handle to storage bracket.

3.2.2 CLOSE TO EMERGENCY SOURCE SIDEBefore proceeding, verify the position of the switch by observing the position of the manual operation handle in Figure 3.1. If the handle is DOWN, the contacts are closed in the EMERGENCY (STANDBY) position. No further action is required. If the handle is UP, proceed with Step 1.

Step 1: With the handle inserted into the moveable contact carrier arm, move the handle DOWN. Be sure to hold on to the handle as it will move quickly after the center of travel.
