6.3. Unit wiring

Before attaching the cable to terminal block.

6.3.1 Power supply cable

Adjust the length of power supply cable to avoid excessive tension with referring ﬁ gure

below.

Power supply cable

20 mm

Earth (Ground)

cable

30 mm

A. For solid core wiring

(1) To connect the electrical terminal, follow the below diagram and connect after

looping it around the end of the cable.

(2) Use the speciﬁ ed cables, connect them securely, and fasten them so that there is no

stress placed on the terminals.

(3) Use an appropriate screwdriver to tighten the terminal screws.

Do not use a screwdriver that is too small, otherwise, the screw heads may be

damaged and prevent the screws from being properly tightened.

(4) Do not tighten the terminal screws too much, otherwise, the screws may break.

(5) See the table for the terminal screw tightening torques.

(6) Please do not ﬁ x 2 power supply cables with 1 screw.

When using solid core cables, do not use the ring terminal. If you use the solid core

cables with the ring terminal, the ring terminal's pressure bonding may malfunction and

cause the cables to abnormally heat up.

B. For strand wiring

(1) Use ring terminals with insulating sleeves as shown in the ﬁ gure below to connect to

the terminal block.

(2) Securely clamp the ring terminals to the cables using an appropriate tool so that the

cables do not come loose.

(3) Use the speciﬁ ed cables, connect them securely, and fasten them so that there is no

stress placed on the terminals.

(4) Use an appropriate screwdriver to tighten the terminal screws.

Do not use a screwdriver that is too small, otherwise, the screw heads may be

damaged and prevent the screws from being properly tightened.

(5) Do not tighten the terminal screws too much, otherwise, the screws may break.

(6) See the table for the terminal screw tightening torques.

(7) Please do not ﬁ x 2 power supply cables with 1 screw.

To peel the ﬁ lm from the lead cable, use a dedicated tool that will not damage the

conductor cable.

When installing a screw on the terminal block, do not cut the cable by overtightening

the screw. On the other hand, an undertightened screw can cause faulty contact, which

will lead to a communication failure.

6.4. Connection of wiring

(1) Remove the control box cover from the control box.

(2) Connect the connection cable.

When switching the DIP switch (SW1), be sure to turn off the power supply to the

indoor unit. Otherwise, the PC board of the indoor unit may be damaged.
