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.
5.10 Typical Installations
5.10.1 Internally Bypassed Installation
The VLT® Soft Starter MCD 600 is installed with a main contactor (AC3-rated). Control voltage must be supplied from the input side
of the contactor.
The main contactor is controlled by the main contactor output (13, 14).
