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.

Arc welding
ABB does not recommend attaching the cabinet by arc welding. However, if arc welding is
the only option, connect the return conductor of the welding equipment to the cabinet frame
at the bottom within 0.5 meters (1’6”) of the welding point.
Note:
The thickness of the zinc plating of the cabinet frame is 100…200 micrometers
(4…8 mil).
WARNING!
Make sure that the return wire is connected correctly. Welding current must not
return via any component or cabling of the drive. If the welding return wire is
connected improperly, the welding circuit can damage electronic circuits in the
cabinet.
WARNING!
Do not inhale the welding fumes.

Air inlet through the bottom of cabinet (C128)
Drives with air intake through the bottom of the cabinet (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.
