Connecting (Power and Control Cable)
Power Wiring:
The main power is supplied to the outdoor unit. The field supplied
connecting cable from the outdoor unit to indoor unit consists of
three (3) wires and provides the power for the indoor unit. Two
wires are high voltage AC power and one is a ground wire.
Consult your local building codes and the NEC (National
Electrical Code) or CEC (Canadian Electrical Code) for special
requirements.
All wires must be sized per NEC or CEC and local codes. Use
Electrical Data table MCA (minimum circuit amps) and MOCP
(maximum over current protection) to correctly size the wires and
the disconnect fuse or breakers respectively.
Per caution note, only copper conductors with a minimum 300 volt
rating and 2/64- -inch thick insulation must be used.
Control Wiring:
A separate shielded copper conductor only, with a minimum 300
volt rating and 2/64- -inch thick insulation, must be used as the
communication wire from from the outdoor unit to the indoor unit.
To minimize voltage drop of the control wire, use the following
wire size and maximum lengths shown in the chart below.

EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
S Wires should be sized based on NEC and local codes.
S Use copper conductors only with a minimum 300 volt .
rating and 2/64 inch thick insulation.
!
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
S Be sure to comply with local codes while running wire
from indoor unit to outdoor unit.
S Every wire must be connected firmly. Loose wiring may
cause terminal to overheat or result in unit malfunction.
A fire hazard may also exist. Therefore, be sure all
wiring is tightly connected.
S No wire should be allowed to touch refrigerant tubing,
compressor or any moving parts.
S Disconnecting means must be provided and shall be
located within sight and readily accessible from the air
conditioner.
S Connecting cable with conduit shall be routed through
hole in the conduit panel.
