Is power voltage of outdoor unit normal?
Is not it an abnormal overload?
Check IPDU P.C. board.
Is winding resistance
between phases of corresponding
compressor normal? (Note 1)
Does voltage drop occur
when other compressor starts?
Is connection of wiring or connection of
connector on IPDU P.C. board normal?
Correct power line.
Correct connector connection or wiring.
Correct cause of overload.
Compressor error
(Motor burning, etc.)
Note 1
After checking the output, when connecting the compressor
lead again to the compressor terminal, check surely there is
no distortion on the Fasten receptacle terminal.
If it is loosened, caulk it with pinchers, etc and then connect
lead to the terminal firmly.
380 – 415V ± 10%
Take off lead cable of compressor.
1. Check resistance between windings:
It is normal if there are 0.7
to 0.9 .
2. Check insulation between outdoor cabinet and terminal:
It is normal if there are 10M
or more.
