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.
Do not use for an application that frequently requires Battery Mode.
 The battery will deteriorate and fail to maintain the specified backup time.
Do not connect the AC input terminal of the unit to its Power Supply Output
terminal during the Battery Mode.
 The unit may fail.
This unit uses lead acid batteries.
 Which are a valuable recyclable resource. Please recycle.
Before performing a withstand voltage test or insulation resistance
test, remove 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.
 Performing the withstand voltage test with the ground wire connected may
damage the surge absorption element built into the power supply input circuit.
Storing the battery in UPS, charge for at 4 hours, then turn off the "Power"
switch of the unit.
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.
 The battery self-discharges even when it not being used, and it goes into
overdischarge state if it is left for a long period of time. 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.
 Turn OFF the unit's "Power" switch when storing it.
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.
