9.3 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 spares of fans from INVT.
Cooling fan replacement:
Read chapter 1 Safety precautions carefully and follow the instructions to perform
operations. Ignoring these safety precautions may lead to physical injury or death, or
equipment damage.
1. Stop the VFD, disconnect the AC power supply, and wait for a time no shorter than the waiting time designated on the
VFD.
2. Remove the fan coverplate.
3. Pull out the fan and remove the pluggable terminal of the fan cable.
4. Replace the fan.
5. Install the new fan inside the VFD, connect the pluggable terminal of the fan cable in the reverse order, put the fan
into the corresponding position of the VFD, and fasten the fan coverplate. Ensure that the air direction of the fan is
consistent with that of the VFD, as shown in Figure 9-2.
