Are OK the
insulation resistance and
coil resistance of
compressor?
Check of the outdoor unit grounding wire/earth leakage breaker
�
Run an independent grounding wire from the grounding screw
of outdoor unit to the grounding terminal on the distribution
panel. (Do not connect to another grounding wire.)
�
In order to prevent malfunction of the earth leakage breaker
itself, confirm that it is conformed to higher harmonic
regulation.
*
Insulation resistance of compressor
• Immediately after installation or when the unit has been left
for long time without power supply, the insulation resistance
may drop to a few M
Ω
because of refrigerant migrated in
the compressor.
When the earth breaker is activated at lower insulation
resistance, check the following points.
�
6 hours after power ON, check if the insulation resistance
recovers to normal. (FDC71-140 only)
When power ON, crankcase heater heat up compressor and
evaporate the refrigerant migrated in the compressor.
�
Check if the earth leakage breaker is conformed to higher
harmonic regulation or not.
Since the unit is equipped with inverter, it is necessary to use
components conformed to higher harmonic regulation in order
to prevent malfunction of earth leakage breaker.
NO
NO
Check the outdoor unit grounding
wire/earth leakage breaker.
Is insulation
of respective harnesses OK?
Is any harness bitten between
pannel and casing
or etc?
YES
YES
Replace compressor.

Secure insulation
