(1) Never short-circuit the output circuits.
Doing so will cause the protective functions of the UPS to activate or the breaker to trip, preventing
output.
(2) Unsuitable load devices
Do not connect laser printers, plain paper fax machines, copy machines, overhead projectors, vacuum
cleaners or hair dryers to the UPS. Since such devices are subject to high transient current surges,
the UPS will detect current surges and the battery backup operation will become no longer possible
when a power outage occurs. There is also the danger of the UPS malfunctioning.
(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 stored without being 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
the batteries in accordance with the UPS storage environment as shown in the table below.
For the time required to recharge the batteries, see §7.2 "Charging UPS."

(5) Insulation testing
Before testing the 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) The UPS can be mounted on a rack (L-shaped support rails are required). For the information of the
needed parts, how to install and more, contact your supplier or SANYO DENKI representative.
