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 hold-
er (clamper).
3. Refix the cover control to the original position with the
screw.
4. Use a recongnized circuit breaker 20A(18K, 24K)
between the power source and the unit. A disconnec-
tion device to adequately disconnect all supply lines
must be fitted.
CAUTION
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 function of a overload protection device.
• Proper starting power is not given to the compressor.
10) 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.
