Miscellaneous
 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
drive. With user-defined cable entries, take care of the degree of protection, fire protection
and EMC compliance.
 Arc welding
ABB does not recommend attaching of the cabinet by arc welding. However, if arc welding
is the only mounting option, proceed as follows: Connect the return conductor of the
welding equipment to the cabinet frame at the bottom within 0.5 meters (1.5 ft) of the
welding point.
Note: The thickness of the zinc coating of the cabinet frame is 100 to 200 micrometers.
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.
