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.
