Connection to the foundation

Connection to the foundation
Four holes for M12 screws are provided on each cabinet panel to secure the cabinet to the
foundation. The fixing dimensions are specified in the dimension drawings.
Every cabinet panel must be attached to the ground using at least two opposing attachment
points (1 screw each in the front and rear part of the cabinet panel).
If this is not possible for reasons of accessibility, then the attachment points of the adjacent
cabinet panels must be correspondingly raised.
Generally, as many attachment points as possible should be used.
3.3.4 Changing the enclosure type, options M23 and M54
To change the type of enclosure from NEMA 1 (standard) to NEMA 1 filtered (IP23), IP43, or
NEMA 12 ventilated (IP54), filter mats are fitted to the ventilation slots in the doors and top
hats. The top hats are mounted after the enclosures have been installed.

The ventilation slots of enclosed drives with a NEMA 1 filtered enclosure are fitted with foam
filters in the air inlet (doors) and air outlet (top hats).
Enclosure IP43
The ventilation slots of enclosed drives with an IP43 enclosure are fitted with foam filters and
