CAUTION
After confirmation of the above conditions, follow these guidelines when performing wiring:
• Always have an individual power circuit specifically for the air conditioner. Always
follow the circuit diagram posted on the inside of the control cover.
Screws fastening the wiring in the casing of electrical fittings may come loose during
•
transporation. Because loose screws may cause wire burn-ou, check that the screws
are tightly fastened.
Check the specifications for the power source.
•
Confirm that electrical capacity is sufficient.
•
• Confirm that 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 specifications.
•
Always install an earth leakage circuit breaker in wet or moist areas.
•
• The following can be caused by a drop in voltage: vibration of a magnetic switch,
damaging the contact point, broken fuses, and disturbance of normal functioning.
• Disconnection from a power supply must be incorporated into the fixed wiring. It must
have an air gap contact separation of at least 3mm in each active (phase) conductors.
Before accessing terminals, all supply circuits must be disconnected.
