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 IMO
Cooling fan replacement

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 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 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 Figure 8-1.
6. Power on the inverter.
Check whether there is
electrolyte
deformation.
Check whether there are
unusual sounds or vibration.
Check whether the bolts
loose.
Check whether there is
decoloration caused due to
overheat.
Check whether there are
foreign matters blocking or
attached to the cooling fan,
air inlets, or air outlets.
Read 1 "Safety Precautions" carefully and follow the instructions to perform
operations. Otherwise, physical injuries or damage to the device may be
caused.
