Service life of the fan
The average service life of the fan is 40,000 hours. In practice, however, the service life may
deviate from this value. Especially a dusty environment can block up the fan.
The fan must be replaced in good time to ensure that the converter is ready for operation.
Applies to all frame sizes
Proceed as follows to remove the fan unit:
Switch off the converter power supply before replacing the fan.
Electric shock as a result of a residual charge in power components
After the power supply has been switched off, it takes up to 5 minutes until the capacitors in
the converter have discharged so that the residual charge is at a non-hazardous level.
• Check the voltage at the converter connections before you carry out any installation
