Omron POWLI Instruction Manual page 12

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 for at least 8 hours 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.
● To charge a battery, connect the AC input plug of the unit to a wall outlet (commercial power).
When storing the unit, charge the battery for at least 8 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 25°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 8 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 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.
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
commercial power supply to another power supply source, such as generating equipment, will cause no
problem. Set the generator's frequency to the same level as that of the commercial power supply.)
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 400V DC 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.
