2. Installation and connection
Notes
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.
●
We recommend keeping the temperature 40
°
C or less when storing the unit for long periods of time.
Connect the unit’s AC input plug to a wall outlet (commercial power) for at least 12 hours at the
following intervals:
- Every 6 months when storage temperature is 25
°
C or less
- Every 2 months when storage temperature is 40
°
C or less
●
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 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, copy machine, 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.
This unit is a full-time commercial power supply method uninterruptible power supply
(UPS). Do not use the unit with the types of devices described below.
●
Devices that experience problems in the event of a momentary power failure of 8 msec. (0.008 sec.) or less.
Switching time of 8 msec. or less occurs, which has the potential to cause connected devices to stop.
●
Devices that require a highly stable power supply.
Instantaneous fluctuations in the output voltage have the potential to cause connected devices to stop.
If the unit is used with an inductive device, check the operation beforehand.
●
With some types of devices, the effect of inrush current may cause this unit to stop operating properly.
●
An inductive device is one that has transformers, coils, motors, etc. built into the 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 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".
●
At the time of battery operation, the maximum voltage (peak voltage) of output (sine 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.
