2. RISK OF VOLTAGE BACKFEED. The system has its own power source (the battery). Isolate the UPS
and check for hazardous voltage upstream and downstream during lockout-tagout operation. Terminal
blocks might be energized even if the system is disconnected from the AC power source.
3. Although the UPS does not contain anti-backfeed (ABF) relays, some backfeed protection is provided.
For example, if some components are damaged in battery mode, the output voltage may feed back
to the input. In this case, a current transformer (CT) is used to detect the bypass current feedback
voltage. If a current backfeed fault condition is detected, the UPS will terminate the inverter output to
avoid personal injury.
