Safety precautions
When moving the unit from a cold place to a warm place, leave it for several
hours before using it.
If the unit is promptly turned ON after being moved to a warmer place, condensation may form inside the
unit and cause it to fail.
Charge the battery soon after purchasing the unit.
If you do not use the unit for a long time after the purchase, the battery may deteriorate and the battery
may become unusable.
The battery can be charged once the AC input plug is connected to commercial power.
Recharge the battery for at least 12 hours every 6 months when the storage
temperature is 25°C or less, or every 2 months when the storage temperature is
40°C or less.
The battery self-discharges even when it not being used, and it goes into over-discharge state if it is left
for a long period of time. The backup time may become shorter or the battery may become unusable.
We recommend keeping the temperature 25°C or less when storing the unit for long periods of time.
Turn OFF the unit's power switch when storing it.
Before storing an additional battery unit, charge it for 24 hours long per unit.
Do not short the output lines of the unit to each other, and do not short the
output lines to the ground.
The unit may fail.
Do not connect the AC 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 (such as a laser printer) to the unit.
The unit repeatedly and frequently switches between Commercial Power Mode and Battery Mode, which
may shorten the life of the battery.
The page printer has a large peak current, so an excess of the connection capacity or a power failure due
to instantaneous voltage drop may be detected.
Use in asynchronous operation mode is recommended if the unit is used in
combination with a device whose power supply frequency fluctuates widely,
such as a personal electric generator.
The unit automatically recognizes the input power frequency when input power is supplied.If the unit is
connected when the input power frequency is not stable at the rated level, the unit may misidentify the
power supply frequency and may fail to operate normally. Synchronous/asynchronous operation setting
can be made with the setting switch 7 8 . Refer to page 29.
Do not install or store the unit in a place exposed to direct sunlight.
The rise of temperature may cause the built-in battery to deteriorate rapidly and become unusable.
Before performing a withstand voltage test or insulation resistance test, make
sure to remove the input surge protection GND screw from the back of the unit.
When in use, make sure the input surge protection GND screw is securely
fastened.
Performing the withstand voltage test with the ground wire connected may damage the surge absorption
element built into the power supply input circuit.
