What this code means

This alarm occurs when the voltage on the Main Contactor is smaller than expected: this means that the Main Contactor Coil has a null voltage when supplied.

Applies to: ZAPI AC-0 SSL Sensored inverter (traction & pump configuration).

Possible causes / checks (from the source)

Check the coils of the Main Contactor (CNA#1) is not short circuited. If it isn’t, probably it is necessary to replace the controller because the driver of the Main Contactor is broken.
