    AMATRONIC LECTRONIC NDUSTRIES 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.

    AMATRONIC LECTRONIC NDUSTRIES A static switch alarm is generated if there is a significant difference between the inverter voltage and the bypass voltage. The maximum acceptable difference can be set to “regular” (20 V) or “extended” (30 V). Setting the “synchronization sensitivity” to “extended” in the static switch high level setup screen may help eliminate repeated static switch alarms, assuming that a 30 V difference upon transfer to bypass is acceptable for your critical loads.
