S&C Instruction Sheet 716-504 29
Installation
(b) Mark the conduit-entrance location for
the control-circuit wiring on the conduit-
entrance plate in the bottom of the
operator enclosure. See Figure 30 on
page 26.
(c) Remove the plate and cut out the
necessary opening. Apply the sealant
furnished and replace the plate. Install
the entrance ttings. Verify the entrance
ttings are properly sealed to prevent
water ingress.
NOTICE
Make sure the polarity of the control
circuit is correct on dc-control-voltage
models. Energizing the switch operator
with polarity reversed will cause
damage to the operator control circuit
and will require repair or replacement
of the operator.
(d) Connect the external control-circuit
wiring (including the space heater source
leads) to the terminal blocks at the
bottom of the enclosure in accordance
with the wiring diagram furnished.
Observe the correct polarity on dc-
control-voltage models.
NOTICE
Trip-circuit conductors and motor-and-
closing circuit conductors must be
adequately sized for the ampacities
indicated on the wiring diagram.
DO NOT apply control voltage to the
operator at this time.
