Please note
400 V appliances: An incor-
rect rotating field will irrepara-
bly damage the compressor.
When replacing the connect-
ing cable, ensure the phases
are connected correctly.

move blockage. Replace motor if
necessary.
If the motor turns easily, notify a spe-
■
cialist.
No action required: Compressor is au-
tomatically reset.
Replace inverter.
