How to Remove the Cover  
Loosen but do not remove four cover screws. Lift cover  
off the four screws and hang on two screws (2 bottom  
or 2 right-hand). See Figure i and ii.  
This will prevent damage to the cable. The cable may  
also be disconnected at the controller or keypad.  
NOTE: Reattach cable before installing cover.

DANGER  
HAZARDOUS VOLTAGE  
(Can Cause Severe Injury or Death)  
Turn OFF all power before installation, adjustment, or removal of transfer switch or any of its components.  
The safe operation of your switch is GE Zenith’s focus.  
The proper storage, installation, operation and mainte-  
nance will help increase the life of the switch.  
NOTE:  
Lug torque values are specified  
in the power panel manual.  
5. Make sure that all covers and barriers are  
installed and properly fastened.  
CAUTION  
Due to hazardous voltage and current, GE Zenith rec-  
ommends that a GE Zenith Certified technician or a  
qualified electrician must perform the

in the Normal Position.  
Each GE Zenith transfer switch is factory wired and  
tested. A complete information package is furnished  
with each switch which includes:

installation and maintenance of the switch.  
b. Description and operation of  
all accessories supplied.  
c. Power panel connection diagram  
and schematic.  
d. Description and identification of  
all customer field connections.  
Equipment Inspection  
and Storage  
Once you have received the transfer switch, inspect  
it for any damage. This includes damage to the enclo-  
sure, power panel, control panel and wiring harness. If  
any damage is found or suspected, file a claim as soon as  
possible with the carrier and notify the nearest GE Zenith  
representative.  
Installation of GE Zenith transfer switches includes:  
a. Mounting the transfer switch cabinet.  
b. Connection of all Normal, Emergency,  
and Load cables or bus bars.  
Before installation, it is necessary to store the transfer  
switch in a clean dry place, protected from dirt and  
water. Provide ample air circulation and heat, if neces-  
sary, to prevent condensation.  
c. Connection of external control  
circuits as required.  
Mounting  
Adequate lifting means must be used to mount the transfer  
switch into place. The recommended method for moving  
the transfer switch using the lifting eyes, where supplied,  
and a spreader bar is

Final Equipment Inspection  
Prior to energizing the transfer switch:  
1. Remove any debris incurred, with a vacuum,  
due to shipment or installation.  
CABINET

NOTE:  
When lifting the switch using a spreader bar,  
height H must be equal to half of distance D.  
WARNING  
CAUTION  
Before drilling conduit entry holes or any  
accessory mounting holes, cover and protect  
the switch and control panel to prevent dirt  
and metal fragments from entering the  
mechanical and electrical components.  
Do not use a blower since debris may  
become lodged in the electrical and  
mechanical components and cause damage.  
2. Verify that all cabled connections are correct.  
3. Check engine start connections and verify  
the correct connection of all control wires.  
4. Check the lug torque values of the power  
connections.  
Failure to do so may result in  
damage and malfunction of the switch.

Functional Test  
FunctionalTest  
Initiate the electrical transfer test by opening the Utility  
side breaker. The delay to engine start timer (P) begins  
its timing cycle. After the P timer has completed its timing  
cycle, the engine start contacts close to start the generator.  
The functional testing of the transfer switch consists of  
electrical tests described in this section. Before proceed-  
ing, read and understand all instructions and review the  
operation of all accessories provided.  
When Generator voltage and frequency reach preset pickup  
points the optional Generator Available LED illuminates.  
Simultaneously, the delay to Generator timer (W) begins  
its timing cycle. When the W time delay is completed the  
switch will transfer to Generator. The optional Utility  
Position LED goes off, and the optional Generator  
Position LED illuminates.  
To begin the test, close the Utility source circuit breaker.  
The controller will illuminate the optional Utility Available  
LED when proper voltage is sensed. Verify the phase to  
phase voltages at the Utility line terminals.  
Next, close the Generator source breaker and start the  
engine generator. The optional Generator Available  
LED will illuminate when proper voltage and frequency  
levels is sensed. If Generator LED is flashing, use the Reset  
button to clear. Check the phase to phase voltages at the  
Generator line terminals. On three phase units, verify  
that the phase rotation of the Generator source is same  
as Utility source.  
Reclose the Utility breaker to retransfer to Utility. The  
delay to Utility timer (T) begins its timing cycle. When  
the T timer has completed its timing cycle, the switch will  
transfer into Utility. The optional Generator Position  
LEDs go off, and the Utility Position LED illuminates.  
The delay engine stop timer (U) begins its timing cycle.  
The generator runs unloaded for the duration of the U  
timing cycle. When the timer completes its timing cycle,  
the generator will stop. The optional Generator Available  
LED goes off.  
After the sources have been verified, shut down the engine  
generator, and put the starting control in the automatic posi-  
tion. Complete the visual inspection of the transfer switch,  
and replace the cabinet cover (or close the cabinet door).
