Status description

Suggested solution

Power

indicator

Green

On

Module AC input is normal

Normal state, no action required

Off

The AC input of the module is abnormal (no input power

supply, input power supply over-voltage and

under-voltage, etc.)

Check whether the input is normal; if the input is normal, replace the

rectifier module

4Hz flashing

(4times/sec)

Manual query status

Normal state, no action required

Alarm

indicator

Yellow

Off

No abnormal alarm

Normal state, no action required

On

Temperature pre-alarm (ambient temperature exceeds 65℃ ~

over-temperature shutdown)

Check whether the ventilation of

module are blocked and whether the ambient temperature is normal

Dormancy shutdown (when the module is in dormancy

shutdown, only the protection indicator is on, and the

module does not report an alarm)

Normal state, no action required

290Vac<Input

voltage<300Vac

Check if the input voltage is normal

Module current limiting

Normal state, no action required

4Hz flashing

(4times/sec)

Module hardware address error

Check if module is inserted in place and locked

0.5Hz

flashing

(1times/2s)

The communication between the module and the outside is interrupted

Replace the rectifier module or

monitoring module; check the CAN bus wiring of the power system for errors

Fault indicator

Red

Off

No abnormal alarm

Normal state, no action required

On

The output is locked due to

over-voltage or the module is not inserted in place

Unplug the rectifier module, wait for more than 1 minute, and then insert it

No output caused by internal fault of rectifier module

Replace the rectifier module
