Connect the cable to the outdoor unit

Outdoor Unit

ARemove the control cover from the unit by loosening the screw.

Connect the wires to the terminals on the control board individually.

BSecure the cable onto the control board with the cord clamp.

CRefix the control cover to the original position with the screw.

DUse a recognized circuit breaker 30A (30k) between the power source and the unit. A disconnecting device to adequately disconnect all supply lines must be fitted.

Terminal block

Over 5mm (2")

Cover control

Conduit panel

Connecting cable

Power supply cord

CAUTION

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

1)Never fail to have an individual power circuit specifically 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 that the starting voltage is maintained at more than 90 percent of the rated voltage marked on the name plate.

6)Confirm that the cable thickness is as specified in the power source specification. (Particularly note the relation between cable length and thickness. (Refer to page 13))

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.

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(0.12in) in each active(phase) conductors.
