Measure
Check connecting cable from inverter
compressor. Replace the connect-
—
ing cable if necessary: See "Connec-
tion and wiring diagram".
!
Please note
400 V appliances: An incorrect
rotating field will irreparably
damage the compressor.
When replacing the connecting
cable, ensure the phases are
connected correctly.
Test coil resistance at compressor.
■
Resistance on all windings should
be similar ( 10 %). Use measuring
±
device suitable for m .
Ω
Replace inverter if required.
■
Check inverter power supply.
Replace inverter.
