(1)
Never short-circuit the output terminals.
Doing so causes preventing output with protective functions to activate, or the circuit breakers to
trip.
(2)
Unsuitable load devices
Do not connect laser printers, plain paper fax machines, copy machines, or overhead projectors,
cleaners, or hair-dryer as load devices. Such devices are subject to high transient current surges This
may cause an overload that could prevent battery backup operation when an outage occurs, and
could damage the UPS.
(3)
Power supply environment
If the UPS is used in an environment subject to long and frequent power outages (more than once a
week), the batteries may not receive sufficient charge, which could result in foreshortened battery
life and premature battery failure
(4)
If the UPS is not operated for a long period, the batteries may require recharging. If the batteries in
the UPS are left uncharged, their service life will be greatly foreshortened. Recharge (refresh charge)
in accordance with the UPS storage environment as shown in the table below. See §9.2 “UPS Charge”
to recharge the UPS.

(5)
Insulation testing
Before testing indoor wiring insulation, shut down the UPS and disconnect the input and output
cables. Conducting an insulation test with the UPS connected may damage electronic components
such as the built-in arrester.
(6)
Rack support rails (not supplied) are required to mount the UPS on a rack. For details, contact your
supplier or SANYO DENKI representative.
