Fans inside the inverter are used to cool the inverter during operation. If the fans do not op-
erate normally, the inverter may not be cooled down and inverter efficiency may decrease.
Therefore, it is necessary to clean dirty fans and replace the broken fans in a timeiy manner.
The operation procedure is as follows:
Step 1 Stop the inverter（see"8.1 Disconnecting Inverter"）
Step 2 Loosen the screw on the sealing plate of the fan module.
Step 3 Press the tab of the latch hook, unplug the cable connection joint outwards, and loosen the
screw on the fan holder.
Step 4 Pull out the fan module, clean the fans with soft brush or vacuum cleaner, and replace them
when necessary.
Step 5 Reinstall the fan back to the inverter in reverse order and restart the inverter.
