9.3 Cooling fan
The inverter’s cooling fan has a minimum life span of 25,000 operating hours. The actual life
span depends on the inverter usage and ambient temperature.
The operating hours can be found through P07.14 (accumulative hours of the inverter).
Fan failure can be predicted by the increasing noise from the fan bearings. If the inverter is
operated in a critical part of a process, fan replacement is recommended once these
symptoms appear. Replacement fans are available from INVT.
Replacing the cooling fan
Read and follow the instructions in chapter Safety Precautions.
Ignoring the instructions would cause physical injury or death, or
damage to the equipment.
1
. Stop the inverter and disconnect it from the AC power source and wait for at least the time
designated on the inverter.
2
. Lever the fan holder off the drive frame with a screwdriver and lift the hinged fan holder
slightly upward from its front edge.
3
. Loose the fan cable from the clip.
4
. Disconnect the fan cable.
5
. Remove the fan holder from the hinges.
6
. Install the new fan holder including the fan in reverse order. Keep the wind direction of the
fan consistent with that of the inverter, as shown below:

. Restore power.
9.4 Capacitors
9.4.1 Reforming the capacitors
The DC bus capacitors must be reformed according to the operation instruction if the
inverter has been stored for a long time. The storing time is counted form the producing date
