10.2 ELECTRICAL WIRING CONNECTION FOR OUTDOOR UNITS
The correct electrical wiring connection for the outdoor unit is shown below:
1 Using the appropriate cable, connect the power circuit to the appropriate terminals as shown on the wiring label and the
illustration below. Connect the power supply cables L1 and N (for 230V 50Hz) or L1, L2, L3 and N (for 400V 50Hz) to the
terminal board, and the earth conductor to the earth screw in the electrical box base plate.
2 Connect the transmission wires between the outdoor unit and the indoor unit to the terminals 1 and 2 on the terminal board.
3 Fix the cable with the clamp supplied in the Electrical Box to ensure strain relief.
4 When routing out cable, make sure that it does not obstruct mounting of the outdoor service cover.
Wiring Method
Keep a distance between each wiring
terminal and attach insulation tape or
sleeve as shown in the figure.

Wiring method with clamp
1
Insert the wires into the cord clamp and clamp
them as shown in the figure.
2
Perform wiring so that wires do not touch the
compressor, refrigerant pipes or edge of the
covers.
Make a loop of wires so that disconnecting the wirings
for replacing the parts is not required.
Fasten the wires so that wires do not touch the high
temperature compressor and the other parts.
