Fastening the MVCS
WARNING!
Do not fasten the MVCS by electric welding, because the welding circuit can
damage electronic circuits and integrity of the station. ABB does not assume any
liability for damages caused by electric welding.
To fasten the MVCS to the foundation, bolt the cabinet through the holes on the base of the
inverter or use the supplied attachment brackets (see figure below). Use bolts and washers
in each connection point.
