NOTE
If installing, as part of the UPS system, a maintenance bypass without a rectifier input
breaker, a minimum of two separate feeds with upstream feeder breakers, or one feed
with two upstream feeder breakers, must be provided: one for the UPS and one for the
maintenance bypass input. DO NOT use one feed or a single feeder breaker to supply both
the UPS and the maintenance bypass.
