3.3.10Maintenance Bypass

Maintenance Bypass switchgear (cabinet, panelboard, switchboard or custom switchgear) allows you to totally isolate the UPS system from all power sources, while you maintain power to the critical load.

Your installation may have a two-breaker, three-breaker or four-breaker maintenance bypass or none at all. The main differences are the locations of the Rectifier Input Breaker and the Bypass Input Breaker (BIB).

Another option that may be present at your site is an alternate power source (generator) and an auto- matic transfer switch (ATS).

Note that to totally isolate the UPS system from all power sources, the Main Input switchgear and battery circuit breakers must also be opened
