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.

Power Connections

SPREADER BAR

GE Zenith transfer switches are supplied with UL listed

45°

solderless screw type terminals as standard for the

H

Source 1, Source 2 and Load power connections.
Table 1 lists the number and sizes of cable lugs supplied
as standard for each switch amp rating.

Connect the Source 1, Source 2, and Load conductors

LIFTING EYES

to the clearly marked terminals on the transfer switch.
Remove surface oxides from cables by cleaning with a
wire brush. Verify that all connections are correct before
tightening the lugs. All cable lug connections must be
tightened to the proper torque values as shown in
Table 2.

NOTE

:

Do not run cables or wiring behind

CABINET

D

front-connected transfer switches.

NOTE

:

When lifting the switch using a spreader bar,
height H must be equal to half of distance D.

Table 1

Engine Start
Control Connections

Engine-start control wires connect to control terminals
beside the Entelli-Switch 250. Engine start terminals are
indicated by a schematic symbol (the symbol indicates
the contact state for a de-energized normal source).
Figure 2 shows the engine-start contacts.

Make all other necessary control connections to the
control panel terminal blocks per the schematics
supplied with the ATS.

NOTE

:

All control wires (18-12

AWG

) must be

torqued to 19 in/lbs.
