Control terminal board

8.7 Connecting the Cables

Indoor

1. The control box of indoor unit is on the left side when

seen from front side.

2. Connect the cable to the indoor unit by connecting the

wires to the terminals on the control board individually

according to the outdoor unit connection (Ensure that

the color of the wires of the outdoor unit and the termi-

nal no. are same as the those of the indoor unit)

• The circuit diagram behind the panel is subject to

change without notice.

• The earth wire should be longer than the common

wires.

• When installing, refer to the circuit diagram behind

the panel front of the indoor unit.

• Connect the wires firmly so that they may not be

pulled out easily.

• Connect the wires according to color codes, refer-

ring to the wiring diagram.

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

1) Never fail to have an individual power specialized for the air conditioner. As for the method of wiring, be guided

by the circuit diagram pasted on the inside of control box cover.

2) Provide a circuit breaker switch between power source and the unit.

3) 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 give rise to burn-out of the wires.)

4) Specification of power source

5) Confirm that electrical capacity is sufficient.

6) Be sure that the starting voltage is maintained at more than 90 percent of the rated voltage marked on the

name plate.

7) Confirm that the cable thickness is as specified in the power sources specification.

(Particularly note the relation between cable length and thickness.)

8) Never fail to equip a leakage breaker where it is wet or moist.

9) The following troubles would be caused by voltage drop-down.

• Vibration of a magnetic switch, damage on the contact point there of, fuse breaking, disturbance to the normal func-

tion of a overload protection device.

• Proper starting power is not given to the compressor.
