● Servicing of batteries should be performed or supervised by personnel knowledgeable of
batteries and the required precautions. Keep unauthorized personnel away from batteries.
When moving the unit from a cold place to a warm place, leave it for several hours
before using it.
● If the unit is moved to a warmer place and the power is turned on soon, the unit failure may occur due to
condensation to the unit.
Charge the battery for at least 12 hours soon after purchasing the unit.
● If you do not use the unit for a long time after the purchase, the property of the battery may deteriorate and
the battery may become unusable.
● To charge a battery, connect the 100-VAC input plug of the unit to a wall outlet (commercial power).
When storing the unit, charge the battery for at least 12 hours and turn off the power
switch.
● Even if the unit is not used, the battery gradually discharges, and if it is left for a long time, it goes into an
over discharge state.
The backup time may become shorter or the battery may become unusable.
● The storable period of the built-in battery of the unit is 6 months after complete charging.
● If you want to store the battery longer than 6 months, connect the AC input plug of the unit to a commercial
power wall outlet for at least 12 hours within 6 months.
● Turn off the power switch of the unit during storage.
Do not short the output lines of the unit each other and the output lines to the ground.
● The unit may fail.
Do not connect the 100 VAC input plug of the unit to its Power Supply Output
Receptacle during the Battery Mode.
● The unit may fail.
Do not connect a page printer (laser printer, etc.) to the unit.
● The Commercial Power Mode and Battery Mode are repeated frequently, which may shorten the life of the
battery.
● As the peak current of a page printer is large, an excess of the connection capacity or a power failure due
to instantaneous voltage drop may be detected.
Do not use the unit for devices that malfunction due to an instantaneous power
failure of 10msec (0.01 second) or less.
● The connected device may stop due to switching time of 10msec or less.
Do not use the unit for inductive devices such as fluorescent lamps.
● Connected devices may stop due to a rectangular wave output.
● Inductive devices include devices incorporating transformers, coils, motors, and so on for their input.
