Appendix 527
According to the tests made, it is you can determine if the malfunction is the result of a faulty
inverter.The following section describes spossible causes of the faulty inverter:
1
Faulty compressor (ground leakage)
1
Faulty fan motor (ground leakage)
1
Entry of conductive foreign particles
