WIRING
All wires must be sized per NEC (National Electrical Code) or
CEC (Canadian Electrical Code) 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 the caution note, only
stranded copper conductors with a 600 volt rating and double
insulated copper wire must be used.
The use of BX cable is not recommended.
Recommended Connection Method for Power and
Communication Wiring − Power and Communication Wiring:
The main power is supplied to the outdoor unit. The field supplied
14/3 power/communication wiring from the outdoor unit to indoor
unit consists of four (4) wires and provides the power for the
indoor unit. Two wires are high voltage AC power, one is
communication wiring and the other is a ground wire.
Recommended Connection Method for Power and
Communication Wiring (To minimize communication wiring
interference)
PowerWiring:
The main power is supplied to the outdoor unit. The field supplied
power wiring 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. To minimize
voltage drop, the factory recommended wire size is 14/2 stranded
with a ground.
Communication Wiring:
A separate shielded Stranded copper conductor only, with a 600
volt rating and double insulated copper wire, must be used as the
communication wire from the outdoor unit to the indoor unit.
Please use a separate shielded 16GA stranded control wire.
CAUTION
!
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 600 volt rating and
double insulated copper wire.
