Step 3
Mark the conduit-entrance location for the control-circuit
wiring on the conduit-entrance plate in the bottom of the
switch operator enclosure. See Figure 2.
Remove the conduit-entrance plate and cut out the
required opening. Replace the plate and make up the
entrance fittings. Apply sealing compound (provided
with each switch operator) when replacing the conduit-
entrance plate. Verify that the entrance fittings are
properly sealed to prevent water ingress.

CAUTION
Remove the two-pole pull-out fuseholders for the motor
circuit and space-heater circuit. See Figure 2.
Failure to remove these fuseholders can result in
accidental energizing of the operator after the external
connections have been completed.
Reinsert the fuseholders only when directed to do
so in the steps that follow.
Remove the blocking from the motor contactors.

Connect the external control-circuit wiring (including
space-heater source leads) to the terminal blocks of the

These illustrations are not applicable
to 12-volt de models. Those models
utilize a number of different compo-
nent parts and a different internal
layout. Among the differences is in-
clusion of a constant-burden battery
charger mounted on a swingout pan-
el, as well as the use of a separate
two-pole control-source disconnect
switch in series with control-source
fuses (located on the inside rear
wall) in lieu of the motor-circuit two-
pole pull-out fuseholder. Those mod-
els, further, include a separate com-
partment beneath the enclosure ,
which houses the 12-volt de battery.
