• When an automatic transfer switch is installed for a standby generator set, the generator engine may crank and start at any time without warning. To avoid possible injury that might be caused by such sudden start-ups, the system's automatic start circuit must be disabled before working on or around the generator or transfer switch. Then place a "DO NOT OPERATE" tag on the transfer switch and on the generator. Remove the Negative (Neg) or (−) battery cable.

For authorized service, reference the dealer locator number found inside the generator owner's manual.

1.1 INTRODUCTION

This 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 application, or improper procedures.

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

1.2 EQUIPMENT DESCRIPTION

The automatic transfer switch is used for transferring critical electrical loads from a UTILITY (NORMAL) power source to an EMERGENCY (GENERATOR) power source.

The transfer switch prevents electrical feedback between the UTILITY and EMERGENCY sources. For that reason, electrical codes require a transfer switch in all standby electric system installations.

When the transfer switch is connected to the engine generator control panel, the control panel constantly monitors the UTILITY voltage and controls the operation of the transfer switch.

Should the UTILITY voltage drop below a preset value, and remain at this low voltage for a preset amount of time, the generator cranks and starts. After the generator starts, the transfer switch transfers the load circuits to the generator, the generator then supplies the loads. When UTILITY returns above a preset level the load is transferred back to the UTILITY and the generator shuts down.

1.3 TRANSFER SWITCH DATA DECAL

A DATA LABEL is permanently affixed to the transfer switch enclosure. Use this transfer switch only with the specific limits shown on the DATA LABEL and on other decals and labels that may be affixed to the switch. This will prevent damage to equipment and property.

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

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

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 supply lines causes extremely hazardous, possibly lethal, electrical shock.

Wiring diagrams and electrical schematics are provided in this manual. Power source and load connections are made at a transfer mechanism, inside the switch enclosure.

2.4.1 3-POLE MECHANISM

These switches (Figure 2.1) are used with a three phase system, when the three phase NEUTRAL line is to be connected to a NEUTRAL lug and is not to be switched.

Figure 2.1 — Typical 3-Pole Transfer Mechanism (200 Amp Shown)

Solderless, screw-type terminal lugs are standard.

The conductor size range is as follows:

Switch Rating Wire Range

100 A #6-2/0 AWG

200A #4-400 MCM

Conductor sizes must be adequate to handle the maximum current to which they will be subjected; based on the 75^irc 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 should enter the switch next to transfer mechanism terminals. If ALUMINUM conductors are used, apply corrosion inhibitor to conductors. Tighten terminal lugs to the torque values as noted on the decal located on the inside of the door. After tightening terminal lugs, carefully wipe away any excess corrosion inhibitor.

All power cables should enter the switch next to the transfer mechanism terminals.

Operation

▲ CAUTION!

Use a torque wrench to tighten the conductors, being sure not to overtighten, or damage to the switch base could occur. If undertightened, a loose connection would result, causing excess heat which could damage the switch base.

Connect power source load conductors to clearly marked transfer mechanism terminal lugs as follows

1. Connect UTILITY (NORMAL) power source cables to switch terminals N1, N2, N3.
2. Connect EMERGENCY (STANDBY) source power cables to transfer switch terminals E1, E2, E3.
3. Connect customer LOAD leads to switch terminals T1, T2, T3.
4. Connect neutral conductors of UTILITY, EMERGENCY and customer LOAD to the neutral block.

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 CIRCUIT WIRES

Control system interconnections consist of UTILITY 1 and 2, 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

1-115 ft (1-35m) No. 18 AWG.

116-185 ft (36-56m) No. 16 AWG.

186-295 ft (57-89m) No. 14 AWG.

296-460 ft (90-140m) No. 12 AWG.

2.6 AUXILIARY CONTACTS

If desired, there are Auxiliary Contacts on the transfer switch to operate customer accessories, remote advisory lights, or remote annunciator devices. A suitable power source must be connected to the COMMON (C) terminal. See Figure 2.2.

Contact operation is shown in the following chart:

	Switch Position
	Utility	Standby
Common to Normally Open	Open	Closed
Common to Normally Closed	Closed	Open

NOTE:

Step 1: With the handle attached to the actuating shaft, move the handle in the direction of the arrow on the switch cover until it stops - DO NOT FORCE. Release handle slowly to allow the spring in the switch box to relax. "OFF" now appears in Window "A" and "ON" appears in Window "B".

3.2.3 RETURN TO NORMAL SOURCE SIDE

Manually actuate switch to return Window "A" to the "ON" position.

3.3 VOLTAGE CHECKS

3.3.1 UTILITY VOLTAGE CHECKS

1. Turn ON the UTILITY power supply to the transfer switch with whatever means provided (such as the UTILITY main line circuit breaker).

⚠️ DANGER!

PROCEED WITH CAUTION. THE TRANSFER SWITCH IS NOW ELECTRICALLY HOT. CONTACT WITH LIVE TERMINALS RESULTS IN EXTREMELY HAZARDOUS AND POSSIBLY FATAL ELECTRICAL SHOCK.

1. With an accurate AC voltmeter, check for correct voltage.

Measure across ATS terminal lugs N1 to N2, N2 to N3, and N1 to N3.

Measure across ATS terminal lugs N1 to NEUTRAL, N2 to NEUTRAL, and N3 to NEUTRAL.

1. Locate the 3 phase power monitor relay. Verify the following:

208 Vac system - LED green and ON

480 Vac system - LED - NORM indicator (green - ON)

The factory setting is 80% of nominal voltage (208 Vac systems = 166 Vac dropout)

(480 Vac systems = 384 Vac dropout)

1. If the LED indicator is not ON, then it will be necessary to adjust the power monitor relay setting. Rotate the adjustment potentiometer in a counter-clockwise direction until the LED turns ON. At this point the 3 phase power monitor relay is the most sensitive to irregular power line conditions.

NOTE:

If the power monitor does not operate properly, check that all three voltages are present, and are of the correct voltage level and phase rotation. To change phase rotation, turn off the utility supply, interchange 2 of the utility power phases.

DANGER!

FAILURE TO TURN OFF THE UTILITY SUPPLY BEFORE WORKING ON THE UTILITY CONNECTIONS OF THE ATS WILL RESULT IN EXTREMELY DANGEROUS AND POSSIBLY FATAL ELECTRICAL SHOCK.

1. When certain that UTILITY supply voltage is correct and compatible with transfer switch ratings, turn OFF the UTILITY supply to the transfer switch.

3.3.2 GENERATOR VOLTAGE CHECKS

1. On the generator panel, set the AUTO/OFF/MANUAL switch to MANUAL position. The generator should crank and start.
2. Let the generator stabilize and warm up at no-load for at least five minutes.
3. Set the generator's main circuit breaker (CB1) to its ON or CLOSED position.

⚠️ DANGER!

PROCEED WITH CAUTION. GENERATOR OUTPUT VOLTAGE IS NOW BEING DELIVERED TO TRANSFER SWITCH TERMINALS. CONTACT WITH LIVE TERMINALS RESULTS IN EXTREMELY DANGEROUS AND POSSIBLY FATAL ELECTRICAL SHOCK.

1. With an accurate AC voltmeter and frequency meter, check the no-load, voltage and frequency.

Measure across ATS terminal lugs E1 to E2, E2 to E3 and E1 to E3.

Measure across ATS terminal lugs E1 to NEUTRAL, E2 to NEUTRAL and E3 to NEUTRAL.

a. Frequency....60-62 Hz
b. Terminals E1-E2, E2-E3, E1-E3....208-212VAC or 470-485
c. Terminals E1-N, E2-N, E3-N....120-122VAC or 272-282

It will also be necessary to verify that the phase rotation of the utility matches the phase rotation of the generator. This can be done by using a phase rotation indicator.

CAUTION!

Failure to do so may result in damage to certain rotary equipment.

1. When certain that UTILITY supply voltage is correct and compatible with transfer switch ratings, turn OFF the UTILITY supply to the transfer switch.
2. Set the generator's main circuit breaker (CB1) to its OFF or OPEN position.
3. Set the AUTO/OFF/MANUAL switch to the OFF position to shut down the generator.

NOTE:

Do NOT proceed until generator AC output voltage and frequency are correct and within stated limits. If the no-load voltage is correct but no-load frequency is incorrect, the engine governed speed probably requires adjustment. If no-load frequency is correct but voltage is not, the voltage regulator may require adjustment.

3.4 GENERATOR TESTS UNDER LOAD

1. Set the generator's main circuit breaker to its OFF or OPEN position.
2. Manually actuate the transfer switch main contacts to their EMERGENCY (STANDBY) position. Refer to "Manual Operation".
3. To start the generator, set the AUTO/OFF/ MANUAL switch to MANUAL. When engine starts, let it stabilize for a few minutes.

4. Turn the generator's main circuit breaker to the ON or CLOSED position. The generator now powers all LOAD circuits. Check generator operation under load as follows:

5. Turn ON electrical loads to the full rated wattage/amper-age capacity of the generator. DO NOT OVERLOAD.

6. With maximum rated load applied, check voltage and frequency across transfer switch terminals E1 and E2. Voltage should be greater than 200 volts (208VAC system), 230 volts (240VAC system), or 460 volts (480VAC system); frequency should be greater than 59 Hz.

7. Let the generator run under rated load for at least 30 minutes. With unit running, listen for unusual noises, vibration, overheating, etc., that might indicate a problem.

8. When checkout under load is complete, set main circuit breaker of the generator to the OFF or OPEN position.

9. Let the generator run at no-load for several minutes. Then, shut down by setting the AUTO/OFF/MANUAL switch to its OFF position.
10. Move the switch's main contacts back to the UTILITY position. For example, load connected to utility power supply. Refer to "Manual Operation". Handle and operating lever of transfer switch should be in down position.
11. Turn on the utility power supply to transfer switch, using whatever means provided (such as a utility main line circuit breaker). The utility power source now powers the loads.
12. Set the generator's AUTO/OFF/MANUAL switch to its AUTO position. The system is now set for fully automatic operation.

Any implied warranties which are allowed by law, shall be limited in duration to the terms of the express warranty provided herein. Some states do not allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you.

IN NO EVENT SHALL GENERAC BE LIABLE FOR ANY INCIDENTAL OR CONSEQUENTIAL DAMAGES, EVEN IF SUCH DAMAGES ARE A DIRECT RESULT OF GENERAC'S NEGLIGENCE.

You also have other rights from state to state.

FOR AUSTRALIA ONLY: Our goods come with guarantees that cannot be excluded under the Australian Consumer Law.
