14
Check system operation beforehand if the unit is used in combination with a
device whose power supply voltage and frequency fluctuate widely, such as a
generator.
l
If the generator’s output voltage/frequency falls out of the unit's input volt-
age/frequency range, the unit will enter Battery Mode.
Do not short the output lines of the unit to each other, and do not short the
output lines to the ground.
l
The unit may fail.
In the event you transfer or sell this unit to a third party, please include all of the
documentation that came with the unit. This is to ensure that the unit is used in
line with the conditions described in the included documentation.
l
This manual contains important safety-related information. Please read and under-
stand the contents of the manual before beginning operation. If this manual is mis-
placed, contact your dealer or download the manual from our website.
Using
Before stopping the commercial power to the unit, turn OFF the power switch of
the unit.
l
The unit enters Battery Mode when commercial power is stopped.
Do not use for an application that frequently requires Battery Mode.
l
The battery will deteriorate and fail to maintain the specified backup time.
Do not connect the AC input plug of the unit to its Power Supply Output Re-
ceptacle during the Battery Mode.
l
The unit may fail.
This unit uses lead acid batteries.
l
Which are a valuable recyclable resource. Please recycle.
Pb
Before performing a withstand voltage test or insulation resistance test, re-
move 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.
l
Performing the withstand voltage test with the ground wire connected may damage
the surge absorption element built into the power supply input circuit.
Storing
Recharge the battery for at least 4 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.
l
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 be-
come shorter or the battery may become unusable.
l
We recommend keeping the temperature 25°C or less when storing the unit for long periods of time.
l
Turn OFF the unit’s power switch when storing it.
Do not install or store the unit in a place exposed to direct sunlight.
l
The rise of temperature may cause the built-in battery to deteriorate rapidly and
become unusable.
