. Installation and Connection
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.
Check system operation beforehand 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. (If the unit is in operation, changing from com-
mercial power supply to another power supply source, such as generating equipment, will cause no
problem.)
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.
Do not perform a withstand voltage test.
● The input circuit has a built-in surge absorption device. A withstand voltage test may break it.
● When performing an insulation resistance test, use the 250VDC range.
Before stopping the commercial power to the unit, turn OFF the power switch of
the unit.
● The unit enters Battery Mode when commercial power is stopped. If you frequently use the unit in Battery
Mode, the battery life may be signifi cantly shortened.
Check the operation beforehand if the unit is used in any mode other than "Output
100V mode".
● In Battery Mode, the maximum voltage (peak voltage) of output (rectangular wave) may be lower than the
maximum voltage in Commercial Power Mode. For this reason, some connected devices may fail to oper-
ate normally.
If this unit is used with an inductive device such as a coil or motor, check the
operation beforehand.
● With some types of devices, the effect of inrush current may cause this unit to stop operating properly.
