2. Installation and connection
Notes
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 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 (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 the 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.
Do not fail to confirm the system operation beforehand if the unit is used combined
with devices which power supply frequency fluctuate widely, such as private electric
generator.
●
This 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 commercial 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 250 VDC 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 significantly shortened.
Do not fail to confirm the system operation beforehand if the unit is used other than
"Output 100V mode". (for BX50FW/BX75SW only)
●
At the time of battery operation, the maximum voltage (peak voltage) of output (rectangular wave) may be
lower than the maximum voltage at the time of usual operation (commercial power supply). For this reason,
some connected devices may fail to operate normally.
