NOTE

The

UPS is shown in a simplified view and does not show multiple UPMs.

NOTE

When installing an MBM, a minimum of two separate feeds with upstream feeder breakers, or a single feed with two upstream feeder breakers,

must be provided: one for the UPS and one for the maintenance bypass input. DO NOT use a single feed or a single feeder breaker to supply both the UPS
and the maintenance bypass.

NOTE

If the load requires a neutral, a bypass source neutral must be provided.
