Equipment Inspection and Storage
Inspect the transfer switch when received to detect any
damage which may have occurred during transit. If damage
is found or suspected, file claims with the carrier.
Before installation, store the transfer switch in a clean
dry place, protected from dirt and water. Provide ample
air circulation and heat to prevent condensation.
Storage Temperature: -30° C to +75° C
(-22° F to +167° F)
Operating Temperature -20° C to +65° C
(Ambient): (-4° F to +149° F)
Humidity: 5% to 95% (non-condensing)
Before installation, check the equipment rating name-
plate on the transfer switch to verify the correct system
voltage.
* Example nameplate is shown in Figure 1.
Mounting
Adequate lifting means must be used to mount the
transfer switch into place. Enough room should be
allowed to open the cabinet door fully for inspection
and servicing of the switch per NEC and local codes.
Before drilling conduit entry 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.
Power Connections
This transfer switch is supplied with UL listed
solderless screw type terminals. Table 2 (see
Page 3) lists the number and sizes of cable
lugs supplied for each switch amp rating.
Connect the Load, Generator and Utility conductors to
terminals on the transfer switch (see Figure 2, Page 3).
Remove surface oxides from cables by cleaning with a
wire brush. Verify that all connections are correct. All
cable lug connections must be tightened to the proper
torque values as shown in Table 1.
DANGER
HAZARDOUS VOLTAGE
(Can Cause Severe Injury or Death)
Turn OFF all power before installation, manual operation or removal of transfer switch or any of its components.
Connecting Engine Start may cause Generator to start. Before connecting, turn Generator OFF.
