Turn OFF all power before installation, adjustment, or removal of transfer switch or any of its components.
Each 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.

d. Description and identification of all customer field connections.
Installation of Zenith transfer switches includes:
a. Mounting the transfer switch cabinet.
b. Connection of all Normal, Emergency, and Load cables or bus bars.
c. Connection of external control circuits as required.
Equipment Inspection and Storage
Immediately inspect the transfer switch when received to detect any damage which may have
occurred during transit. If damage is found or suspected, file claims as soon as possible with
the carrier and notify the nearest Zenith representative.
Before installation, it is necessary to store the transfer switch in a clean dry place, protected from
dirt and water. P
rovide ample air circulation and heat, if necessary, to prevent condensation.
Storage Temperature: -30° C to + 85° C (-22° F to +185° F)
Operating Temperature (Ambient): -20° C to +75° C (-4° F to +167° F) [30-260 Amps]
-20° C to +40° C (-4° F to +140° F) [400-800 Amps]
Humidity: 5% to 95% (non-condensing)
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.
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. F
ailure to do so may result in damage and malfunction of the switch.
