What this code means

In working condition, a resistance connected between the key and the Rail Capacitors, keeps the Rail Capacitors charged before the Main Contactor closes. When the voltage on the Rail Capacitors (measured on the phase V) is low and does not increase when the main contactor is opened this alarm occurs.

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

Possible causes / checks (from the source)

Three possibilities: - Another device, connected in parallel with the Rail Capacitors, has a failure - At least a motor phase is not connected to the controller or broken. - A Power failure or a Logic Failure occurred in the controller. In this case it is necessary to replace the controller.
