The lead battery used in the unit has a limited lifespan.
(The life varies depending on your storage/use environment and backup frequency.)
The nearer the end of the life is, the more rapidly deterioration proceeds.
1. Battery life expectancy (* Not a guaranteed performance)
2. Methods for checking the battery
There are two methods for checking the battery.
• Perform a self-diagnostic test. (See page 30.)
• Measure the backup time. (See page 34.)
By measuring the backup time, the battery life can be determined more accurately.
If the measured value is equal to the "initial value of the backup time" or less than half the value
obtained from the graph of "Estimated backup time" on page 35, replace the battery.
• When you compare the "initial value of the backup time" you measured and the current
backup time, make the capacity of devices connected to the UPS same as when you mea-
sured the initial value to make judgment accurately.
When maintaining the connected equipment, turn OFF the unit’s power
switch to stop the output, and stop the supply of commercial power.
●
Even if commercial power to the UPS is stopped while it is in operation, the power output of this
unit does not stop and power is supplied from the receptacle.
Do not disassemble, repair, or modify the unit.
