5.2.1 Replacing the cooling fan
The service life of the cooling fan
The average service life of the cooling fans is 40,000 hours. In practice, however, the service
life may deviate from this value. Especially a dusty environment can occlude the fan.
The fan must be replaced in good time to ensure that the inverter is available.
Replacing the external cooling fan FSA … FSC
The PM230 Power Modules have two sets of cooling fans, one fan is internal and the other is
external. The external cooling fan is mounted at the rear of the Power Module.
The external cooling fans on the PM230 FSA to FSC are a complete fan modules and do not
require any tools to remove and replace the fans. The power connection on the fan unit is an
integral part of the fan module and does not require separate removal.
