5.9.5 Ground Terminations

Models MCD6-0654B~MCD6-1250B/MCD6-0590C~MCD6-1134C have a ground terminal on each side of the soft starter, near the
top back corner. Either grounding point may be used.
Models MCD6-0020B~MCD6-0579B/MCD6-0160C~MCD6-0448C do not require a protective earth connection. All internal conduc-
tive parts are fully enclosed by a non-conductive outer case.
