CAUTION
Before measuring the compressor motor windings resistance, measure the
resistance of the multimeter probes by holding the probes against each other. If the
measured resistance is NOT 0 Ώ, this value MUST be subtracted from the measured
winding resistance.
4
Measure the resistance between the compressor motor windings U-V, V-W
and U-W.
Result:
All measurements MUST be approximately the same.
Compressor motor winding
measurements are correct?
Action
Yes
Continue with the next step.
No
Replace the compressor, see
153].
5
Measure the continuity of the U, V and W wires between the compressor and
the PCB. If no continuity, correct as needed, see

7
Install the compressor wire terminals cover.
8
Install the compressor insulation.
9
Turn ON the power using the respective circuit breaker.
10
Start the unit operation via the user interface.
CAUTION
NEVER operate the compressor with the compressor wire terminals cover removed.
11
Wait for – or create condition to operate the compressor.
12
Once the compressor operates, measure the U-V-W inverter voltages.
ALWAYS measure at the PCB side.
Result:
All measurements MUST be the same.
