This allows Maintenance bypass for system repair or maintenance.The critical load is NOT protected in the Maintenance bypass mode.• Three breaker configuration (used with single-feed systems): Maintenance Bypass (MBP) andMaintenance Isolation (MIS) breakers, and a Bypass Input Breaker (BIB) enable power to completelybypass the UPS. The UPS can then be safely serviced or replaced without interrupting power to criticalsystems.• Four breaker configuration (used with dual-feed systems): Maintenance Bypass (MBP) and MaintenanceIsolation (MIS) breakers, and a Bypass Input Breaker (BIB) enable power to completely bypass the UPS. ARectifier Input Breaker (RIB) provides a convenient method for removing power from the UPS when usingthe maintenance bypass to supply the load. The UPS can then be safely serviced or replaced withoutinterrupting power to critical systems.Figure 1 shows the SIAC-B.
