Cable duct in the floor below the cabinet


A cable duct can be constructed below the 500 mm wide middle part of the cabinet. The
cabinet weight lies on the two 50 mm wide transverse sections which the floor must carry.
Prevent the cooling air flow from the cable duct to the cabinet by bottom plates. To ensure
the degree of protection for the cabinet, use the original bottom plates delivered with the
unit. With user-defined cable entries, take care of the degree of protection, fire protection
and EMC compliance.

Air inlet through the bottom (option +C128)


Drives with air intake through the bottom of the cabinet (option +C128) are intended for
installation on an air duct in the floor. Each cubicle (except top entry adapter and joining
cubicles) have an inlet through the bottom plate. The option also adds a 130 mm deep
inlet area at the back of the cubicle.
An example of the air inlets in the cabinet bottom plate is shown below. Refer also to the
dimension drawings delivered with the drive.
Support the plinth of the cabinet all round.
