8.3 Cooling fan
The service life of the cooling fan of the inverter is more than 25,000 hours. The actual service life of
the cooling fan is related to the use of the inverter and the temperature in the ambient environment.
You can view the running duration of the inverter through P07.14 (Accumulated running time).
The increase of the bearing noise indicates a fan fault. If the inverter is applied in a key position,
replace the fan once the fan starts to generate unusual noise. You can purchase spare parts of fans
from INVT.

Read the safety precautions carefully and follow the instructions to perform
operations. Otherwise, physical injuries or damage to the device may be
caused.
1. Stop the device, disconnect the AC power supply, and wait for a time no shorter than the waiting
time designated on the inverter.
2. Open the cable clamp to loose the fan cable (for inverters of 380 V, 1.5 to 30 kW, the middle
casing needs to be removed).
3. Remove the fan cable.
4. Remove the fan with a screwdriver.
5. Install a new fan in the inverter in the reverse steps. Assemble the inverter. Ensure that the air
direction of the fan is consistent with that of the inverter, as shown in the following figure.
