8.3 Cooling fan
The service life of the cooling fan of the VFD is more than 25,000 hours. The actual service life
of the cooling fan is related to the use of the VFD and the temperature in the ambient
environment.
You can view the running duration of the VFD through P07.14 (Accumulated running time).
The increase of the bearing noise indicates a fan fault. If the VFD 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 1 "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 VFD.
2. Open the cable clamp to loose the fan cable (for VFDs of 004G/5R5P
–030G/037P, 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 VFD in the reverse steps. Assemble the VFD. Ensure that the air
direction of the fan is consistent with that of the VFD, as shown in the Figure 8-1.
