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.
•
• Check the specifications for the power source.
• Confirm that electrical capacity is sufficient.
• 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.
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.
• 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.
• Confirm that starting voltage is maintained at more than 90 percent of the rated voltage
marked on the name plate.
• Before accessing terminals, all supply circuits must be disconnected.
• 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.
