Replace the f ilter and/or
check and correct the
wiring between the f ilter
and the inv erter
This error can be generated by even transient glitches in the mains supply due to
overloading or other factors. Therefore it can be useful to check, in the inverter error
log, the value of mains voltage recorded at the time when the error occurred.
Follow the procedure step by step to correctly diagnose the problem. Take particular care with the
checks highlighted by circled numbers, which are described in detail below:
Place the tester probes across terminals L1 and L2 of the inverter. The measured voltage
(1)
should be 220 VAC.
As for step (1) but across terminals 2 and 6 of the relay.
(2)
As for step (1) but across terminals 4 and 8 of the relay.
(3)
As for step (1) but across the output terminals of the filter.
(4)
On a 110VAC model, check that the autotransformer properly generates the
220VAC input to the filter. Otherwise check and/or replace the autotransformer.
