Figure 6-7. Typical maintenance bypass panel
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.
