Note
Replacing the filter mats
If you do not replace dirty filter mats, this can cause a premature thermal shutdown of the
drive.
Ordering data are available in the spare parts lists.
Preparatory steps
● Disconnect the cabinet from the power supply (do not forget the external power supplies).
● Allow unimpeded access to the grille area of the doors.
Note
The cabinet must be disconnected from the power supply to prevent the fans from drawing in
contaminated external air. If an external power supply for the fans is used, take the coasting-
down period of the fan into account or switch off the power supply.
