9 Troubleshooting and Maintenance

User Manual

Step 9

Press on the ribbing of the locking hooks
and pull the cable outwards.

Step 10

Remove the fans out of the inverter.

Step 11

Clean the fan with soft brush or vacuum cleaner; or replace the broken fans.

Step 12

Reassemble the fans back into the inverter and restart the inverter.

Cleaning Air Inlet and Outlet

A huge amount of heat is generated in the process of running the inverter. The
inverter adopts a controlled forced-air cooling method.

In order to maintain good ventilation, please check to make sure the air inlet and
outlet are not blocked.

Clean the air inlet and outlet with soft brush or vacuum cleaner if necessary.
