Safety / Installation
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.
CAUTION 
Due to hazardous voltage and current, GE Zenith rec- ommends that a GE Zenith Certified technician or a qualified electrician must perform the
installation and maintenance of the switch.
Equipment Inspection and Storage
Once you have received the transfer switch, inspect it for any damage. This includes damage to the enclosure, 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.
Before installation, if it is necessary, 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.

Final Equipment Inspection
Prior to energizing the transfer switch:
1.Remove any debris incurred, with a vacuum, due to shipment or installation.
WARNING 
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 and that phase rotation of both sources match.
3.Check engine start connections.
4.Verify the correct connection of all control wires.
5.Check settings of all timers and adjust as necessary.
6.Adjust any optional accessories as required.
7.Check the lug torque values of the power connections.
NOTE: Lug torque values are specified in table 2 on pg.4.
8.Make sure that all covers and barriers are installed and properly fastened.
NOTE: Power panels ship from GE Zenith in Source 1 Position.
Each GE Zenith transfer switch is factory wired and tested. A complete information package is furnished with each switch which includes:
a.Sequence of operation.
b.Description and operation of all accessories supplied.
c.Power panel connection diagram and schematic.
d.Description and identification of all customer field connections.
Installation of GE Zenith transfer switches includes:
a.Mounting the transfer switch cabinet.
b.Connection of Source 1, Source 2, and Load cables or bus bars.
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 illustrated in Figure 1. Enough room should be allowed to open the cabinet doors fully for inspection and servicing of the switch per NEC and local codes.
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.
Failure to do so may result in
damage and malfunction of the switch.
