28 Planning the cabinet assembly

Grounding of mounting structures

Make sure all cross-members or shelves on which drive system components are
mounted are properly grounded and the connecting surfaces left unpainted.
Note: Ensure that the components are properly grounded through their fastening
points to the installation base.
Note: It is recommended that the EMC filter (if present) and the drive module be
mounted on the same mounting plate.

Planning the fastening of the cabinet

WARNING! Do not fasten the cabinet by electric welding. ABB does not
assume any liability for damages caused by electric welding as the welding
circuit may damage electronic circuits in the cabinet.
