Description

Power indicator

Green

Steady on

The rectifier has an AC power input.

Off

The rectifier has no AC power input.

The rectifier is faulty.

Alarm indicator

Yellow

Blinking

No alarm is generated.

Steady on

The rectifier generates an alarm for power limiting due to ambient overtemperature.

The rectifier protects against AC input overvoltage or undervoltage.

The rectifier is hibernating.

Fault indicator

Red

Off

The rectifier is running properly.

Steady on

The rectifier locks out due to output overvoltage.

The rectifier has no output due to an internal fault.
