7. WIRING
One-five models:
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.
