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.
