Figure 6-10. Simplified Dual-Feed UPS with maintenance bypass panel
NOTE
If installing a maintenance bypass, 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
or rectifier input breaker (RIB) (if installed) and one for the maintenance bypass input. DO NOT
use a single feed or a single feeder breaker to supply both the UPS or RIB and the maintenance
bypass. If a bypass input breaker (BIB) is installed in the maintenance bypass and a single-feed
UPS is being installed, a single feed to the maintenance bypass is acceptable for supplying both
the UPS and the bypass.
