Information
Since the data is a typical lifetime (L
10
), it is recommended that the fan be
replaced already when 70% the service life has been reached, in order to
avoid an unexpected failure during the running process.

Replacing the fan
The fan is located on the top of the module. To change the fan, the fan cover
on the top of the control must be removed.
For ordering information on the fan cover, see chapter "Accessories".
Caution
Operation without fan is not permitted since this could overheat the module
and destroy it.
