PERATING THE MAINTENANCE BYPASS SWITCH
Maintenance bypass is an optional feature. In maintenance bypass mode, the UPS output terminals
continue to supply power to the load, but the interior of the UPS is isolated from all power flows. This
enables a technician to work safely on the UPS (after turning off the battery circuit breaker or disconnecting
the battery fuse) without any interruption of power to the load.
When present, the three maintenance bypass switches are located on the Centric's rear panel.
