5.2.1 Replacing the cooling fan
The service life of the cooling fan
The average service life of the cooling fans is 50,000 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.
