•
•
Always have an individual power circuit specically 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
transportation. Because loose screws may cause wire burn-out, check that the screws are
tightly fastened.
Check the specications 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.
• 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.
NOTE: To satisfy the EMC compulsory regulations, which is required by the international standard
CISPR 14-1:2005/A2:2011 in specific countries or districts, please make sure you apply the
