2.3 UPS Power Connection

DANGER: In order to avoid the Mains power switch current
overload when UPS carries with rating load, the Mains power switch rating
current must be more than the bypas switch rating current.(bypass mode
max current refer to 1.4 product specification)
It is suggested to install an external isolating device against current
backfeed between Mains input and UPS (see Fig.). 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.
