GENERAL HAZARDS

• Any AC generator that is used for backup power if

a NORMAL (utility) power source failure occurs,

must be isolated from the NORMAL (utility) power

source by means of an approved transfer switch.

Failure to properly isolate the NORMAL and

STANDBY power sources from each other may

result in injury or death to electric utility workers,

due to backfeed of electrical energy.

• Improper or unauthorized installation, operation,

service or repair of the equipment is extremely

dangerous and may result in death, serious per-

sonal injury, or damage to equipment and/or per-

sonal property.

• Extremely high and dangerous power voltages are

present inside an installed transfer switch. Any

contact with high voltage terminals, contacts or

wires will result in extremely hazardous, and pos-

sibly LETHAL, electric shock. DO NOT WORK ON

THE TRANSFER SWITCH UNTIL ALL POWER

VOLTAGE SUPPLIES TO THE SWITCH HAVE

BEEN POSITIVELY TURNED OFF.

• Competent, qualified personnel should install,

operate and service this equipment. Adhere strict-

ly to local, state and national electrical and build-

ing codes. When using this equipment, comply

with regulations the National Electrical Code

(NEC), CSA Standard; C22.1 Canadian Electric

Code and Occupational Safety and Health

Administration (OSHA) have established.

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 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. Generac, however, reserves the right to change,

alter or otherwise improve the product at any time

without prior notice.

1.2 EQUIPMENT DESCRIPTION

The pre-packaged transfer switch is designed to use

with pre-packaged standby generator control panels.

It is used for transferring critical electrical loads from

a NORMAL (utility) power source to a STANDBY

(emergency generator) power source. Such a transfer

of loads occurs automatically when the NORMAL

power source fails or is subsequently reduced and

the STANDBY source voltage and frequency have

reached an acceptable level. The transfer switch pre-

vents electrical feedback between two different power

sources (such as the NORMAL and STANDBY

sources) and, for that reason, codes require it in all

standby electric system installations.

Once the transfer is completed, the STANDBY power

source then powers electrical loads connected to the

transfer switch. When NORMAL source voltage above

an acceptable (preset) level has been restored, circuit

board action in the pre-packaged control panel initi-

ates re-transfer back to NORMAL power source. After

this re-transfer, the circuit board signals to open the

start circuit to the generator, which shuts down the

engine. The circuit board is then "armed" and ready

for the next drop in NORMAL source voltage.

NOTE:

Keep in mind the pre-packaged transfer switch is

without any kind of electronic controls. It receives

signals solely from circuit boards contained in the

prepackaged control panel.

1.3 TRANSFER SWITCH DATA PLATE

Affixed permanently to the transfer switch door is a

DATA PLATE. Use the transfer switch only within the

specific limits shown on the DATA PLATE and on

other decals and labels that may be affixed to the

switch. This prevents damage to equipment, possible

injury to personnel, and provides long and trouble-

free life for the equipment.

When requesting information or ordering parts for

this equipment, make sure to include all information

from the DATA PLATE.

When requesting information or ordering parts for this

equipment, make sure to include all information from

the DATA PLATE.

Record your Model and Serial numbers in the space

provided below for future reference.

1.4 TRANSFER SWITCH ENCLOSURE

The standard switch enclosure is a National

Electrical Manufacturer's Association (NEMA) 1 type.

NEMA 1 type enclosures primarily provide protection

against contact with the enclosed equipment and

against a limited amount of falling dirt.

1.5 SAFE USE OF TRANSFER SWITCH

Before 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.

Generac recommends you make a copy of the SAFE-

TY RULES and post them near the transfer switch.

Also, be sure to read all instructions and information

you may find on tags, labels and decals affixed to the

equipment.

Two publications that outline the safe use of transfer

switches are the following:

• National Electrical Code

• UL 1008, STANDARD FOR SAFETY-AUTOMATIC

2.1 INTRODUCTION TO INSTALLATION

This equipment has been wired and tested at the fac-

tory. Installing the switch includes the following pro-

cedures:

• Mounting the enclosure.

• Connecting power source and load leads.

• Connecting the generator start circuit.

• Installing/connecting any options and accessories.

• Testing functions.

2.2 UNPACKING

Carefully unpack the transfer switch. Inspect closely

for any damage that might have occurred during

shipment. The purchaser must file with the carrier

any claims for loss or damage incurred while in tran-

sit.

Check that all packing material is completely

removed from the switch prior to installation.

Attach any lifting device to the transfer switch mount-

ing holes or brackets only. DO NOT LIFT THE

SWITCH AT ANY OTHER POINT.

2.3 MOUNTING

Transfer switch components are generally mounted

in a standard NEMA 1 type enclosure (Figure 2.1).

Other options are available such as NEMA 34 and

NEMA 12.

Handle transfer switches carefully when

installing. Do not drop the switch. Protect the

switch against impact at all times, and against

construction grit and metal chips. Never install

a transfer switch that has been damaged.

Install the transfer switch as close as possible to the

electrical loads that are to be connected to it. To pre-

vent 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

Make sure to turn OFF both the normal (Utility)

and standby (generator) 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 pro-

vided in this manual. Power source and load connec-

tions are made at a transfer mechanism, inside the

switch enclosure.

switches as follows (Figure 3.2):

1. Check that the generator's Auto/Off/Manual

switch has been set to OFF position.

2. Attach the square opening of the manual handle

over the square shaft at lower right corner of

transfer mechanism.

3. Move the manual handle UP. When movement

stops at NEUTRAL, return handle to its original

position and actuate again.

4. Observe the changeover display on transfer

mechanism as follows:

• If utility arrow is aligned with GREEN band, load

is connected to UTILITY (normal) power source.

• If STANDBY arrow is aligned with GREEN band,

LOAD is connected to STANDBY (emergency)

source.

5. Repeat steps 3 and 4 several times, being sure the

switch main contacts actuate normally to all posi-

tions.

6. When certain that switch operates normally, actu-

ate the main contacts to their UTILITY (normal)

source.

NOTE:

LOAD must be connected to UTILITY source

before proceeding. That is, the GREEN BAND

must be next to the UTILITY arrow and the RED

band must be next to the STANDBY arrow.

3.4 VOLTAGE CHECKS

1. Turn ON the UTILITY power supply to the trans-

fer switch with whatever means provided (such as

the UTILITY maim line circuit breaker).

PROCEED WITH CAUTION. THE TRANSFER

SWITCH IS NOW ELECTRICALLY HOT. CONTACT

WITH LIVE TERMINALS RESULTS IN EXTREMELY

HAZARDOUS AND POSSIBLY FATAL ELECTRICAL

SHOCK.

2. With an accurate AC voltmeter, check for correct

voltage across terminal lugs N1 and N2; N1 to

NEUTRAL; and finally N2 to NEUTRAL (Figure

2.5 on Page 5).

3. When certain that UTILITY supply voltage is correct

and compatible with transfer switch ratings, turn

OFF the UTILITY supply to the transfer switch.

4. On the generator panel, set the Auto/Off/Manual

switch to MANUAL position. The generator

should crank and start.

5. Let the generator stabilize and warm up at no-

load for at least five minutes.

6. Set the generator's main circuit breaker (CBI ) to

its ON or CLOSED position.

PROCEED WITH CAUTION. A GENERATOR OUT-

PUT VOLTAGE IS NOW BEING DELIVERED TO

TRANSFER SWITCH TERMINALS. CONTACT WITH

LIVE TERMINALS RESULTS IN EXTREMELY DAN-

GEROUS AND POSSIBLY FATAL ELECTRICAL

SHOCK.

7. With an accurate AC voltmeter and frequency

meter, check the no-load, voltage and frequency

meter at transfer switch terminal lugs E1, E2 and

NEUTRAL. Readings should be as follows:

a. Frequency ........................61-63 Hz

b. Terminals E1 and E2 ......242-253 volts

c. Terminal E1 to Neutral ....121-126 volts

d. Terminal E2 to Neutral ....121-126 volts

8. Set the generator's main circuit breaker (CBI ) to

its OFF or OPEN position.

9. To shut down the generator, set its

Auto/Off/Manual switch to OFF position.

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 fre-

quency is incorrect, the engine governed speed

probably requires adjustment. If no-load frequen-

cy is correct but voltage is not, the voltage regula-

tor may require adjustment.
