CAUTION
After con rmation of the above conditions, follow these guidelines when performing wiring:
• 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 ttings may come loose during
transporation. Because loose screws may cause wire burn-ou, check that the screws are tightly
fastened.
• Check the speci cations for the power source.
• Con rm that electrical capacity is su cient.
• Con rm that starting voltage is maintained at more than 90 percent of the rated voltage
marked on the name plate.
• Con rm that the cable thickness is as speci ed in the power source speci cations.
• 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 xed 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 speci c countries or districts ,please make sure you apply the
