details about the replacement, contact the local INVT office.

6.2.2 Cooling fan

The service life of the cooling fan of the inverter unit is more than 35000 hours. The actual service life of the
cooling fan is related to the use of the unit and the temperature in the ambient environment.
You can view the running duration of the unit through P07.14 (Accumulated running time).
The increase of the bearing noise indicates a fan fault. If the unit is applied in a key position, replace the fan
once the fan starts to generate unusual noise. You can purchase spares of fans from INVT.
Cooling fan replacement:

Step 1 Stop the unit, disconnect the AC power supply, and wait for a time no shorter than the waiting time
designated on the unit.
Step 2 Remove the fan module front cover from the unit housing.
Step 3 Remove the fan module connection cable.
Step 4 Pull out the fan box and remove the fan with a screwdriver.
Step 5 Install a new fan in the fan box. Insert the fan module connection cable to the connector in reverse
