1) It is suggested to install an external isolating device against
current backfeed between Mains input and UPS (see Fig.4-6).
After the device is installed, it 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.
For safety, please cut off the mains power switch before
installation!
