Connecting Cables between Indoor Unit and Outdoor Unit

3) Connecting the cable to Outdoor Unit

1. Remove the Cover control from the unit by

loosening a screw.

Connect the wires to the terminals on the control

board individually as following.

2. Secure the cable onto the control board with the

holder (clamper).

3. Refix the cover control to the original position with

the screw.

4. Use a recongnized circuit breaker between the

power source and the unit. A disconnection device

to adequately disconnect all supply lines must be

fitted.

After the confirmation of the above conditions, prepare the wiring as follows:

1) Never fail to have an individual power circuit specialized for the air conditioner. As for

the method of wiring, be guided by the circuit diagram posted on the inside of control

cover.

2) The screw which fasten the wiring in the casing of electrical fittings are liable to come

loose from vibrations to which the unit is subjected during the course of

transportation. Check them and make sure that they are all tightly fastened. (If they are

loose, it could cause burn-out of the wires.)

3) Specification of power source.
4) Confirm that electrical capacity is sufficient.
5) See to it that the starting voltage is maintained at more than 90 percent of the rated

voltage marked on the name plate.

6) Confirm the cable thickness which is specified as the power source specification.

(Particularly note the relation between cable length and thickness.

7) Always install an earth leakage circuit breaker in a wet or moist area.
8) The following would be caused by voltage drop.

•

Vibration of a magnetic switch, which will damage the contact point, fuse breaking,

disturbance of the normal function of the overload protection device.

9) The means for disconnection from a power supply shall be incorporated in the fixed

wiring and have an air gap contact separation of at least 3mm in each active(phase)

conductors.
