Installation

MSC-3 with a DC Supply

Some models of MSC-3 may be used with a DC supply. There are a number of issues to be considered
in properly applying MSC-3 in this situation, some of which involve the characteristics of the particular
DC supply to be used.

Please consult the factory for proper application of MSC-3 on DC supply systems.
