CAUTION:

If the UPS does not have an automatic protection device against current backfeed, install an

external isolating device. After the device is installed, you must add a warning label with the following

wording or the equivalent on the external AC contactor: RISK OF VOLTAGE BACKFEED. Isolate the UPS before

operating on this circuit, then check for hazardous voltage between all terminals.

NOTE:

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 the personal injury.
