Hazardous Voltage!
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Failure to disconnect power

Standard Wiring

1. Location of the applicable electrical service entrance is
illustrated in "Unit Dimensions, " p.
unit's power wiring connections at Compressor
Contactor # 1 (CC1) inside the unit control panel. Refer
to the customer connection diagram that is shipped
with the unit for specific termination points
2. Provide proper grounding for the unit in accordance
with local and national codes.
Optional TBUE Wiring (Through the Base
Electrical Option)
1. Location of the applicable electrical service is
illustrated below. Refer to the customer connection
diagram that is shipped with the unit for specific
termination points. The termination points, depending
on the customer option selected would be a factory
mounted non-fused disconnect switch (UDC) or circuit
breaker (UCB). If neither a factory mounted non-fused
disconnect switch (UDC) or circuit breaker (UCB) was
factory mounted, field wiring connections should be
terminated in the control box at Compressor Contactor
# 1 (CC1).
2. Provide proper grounding for the unit in accordance
with local and national codes.
Note: Black Gasket is shipped from the factory and is
located in the literature Ship With bag in the control
box. Apply Black Gasket around conduit plate on all
