Connect the cable to the outdoor unit (for SC 13xx models)
1. The connection cables of indoor and outdoor units have been connected to the terminals on the con-
trol board except the grounding wire(Y/G), only white plug connectors exposed.
2. Remove the control cover from the outdoor unit by loosening the screw.
3. Hold the indoor plug connector and insert the mating plug connector located on the outdoor unit until
it fixed with a clicking sound (A > A* 'click' / B > B* 'click'). Secure the cable onto the control board with
the cord clamp.
4. Connect the grounding wire to the terminal on the control board individually.

CAUTION
After the confirmation of the above conditions, prepare the wiring as follows:
• Always 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.
• 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.)
• Check specification of power source.
• Confirm that supplied electrical capacity is sufficient.
• See to that the starting voltage is maintained at more than 90 percent of the rated voltage
marked on the name plate.
• Confirm that the cable thickness is as specified in the power source specification.
• Always install an earth leakage circuit breaker.
• 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.
• 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.
Connect the cable to the outdoor unit (for S 13xx models)
