Precautions to be taken for power supply wiring

Use a round crimp-style terminal for connection to the power supply terminal block.

In case it cannot be used due to unavoidable reasons, be sure to observe the following instructions.

(Refer to Fig. 29)

• Do not connect wires of different gauge to the same power supply terminal. (Looseness in the connection

may cause overheating.) (Refer to Fig. 30)

• When connecting wires of the same gauge, connect them according to. (Refer to Fig. 30)

• In wiring, make certain that prescribed wires are used, carry out complete connections, and fix the wires so

that external forces are not applied to the terminals.

Tightening torque for the terminal screws.

• Use the correct screwdriver for tightening the terminal screws. If the blade of screwdriver is too small, the

head of the screw might be damaged, and the screw will not be properly tightened.

• If the terminal screws are tightened too hard, screws might be damaged.

Refer to the table below for the tightening torque of the terminal screws.

• If the strand wire is used, do not solder it.

remote controller) (Refer to Fig. 32)

• 2 remote controllers control: 2 remote controllers control 1 indoor unit. (Refer to Fig. 34)

Do not use cords for the transmission wiring.

Ex: VCTF (not allowed), VV cable (allowed)
