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. Firmly tighten the terminal screws to prevent them loosening. After tightening, pull
the wires lightly to confirm that they do not move. (If they are loose the unit, the unit
will not operate normally or it can 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.
7. Do not 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 in each active(phase)
conductors.
