5. Maintenance and inspection

5-1 Checking the battery

The sealed lead-acid battery mounted in the UPS has its own life. (The life of the battery varies depending on
storage conditions, the operating environment, and backup frequency.) As the end of the battery life draws
near, deterioration takes place much faster. Check the battery regularly.
1. Battery life (standard replacement period)
Ambient temperature
20°C
30°C
* The battery deteriorates even in storage. The higher the temperature is, the shorter the life
becomes. Include storage time in the life expectancy period above.
2. How to check the battery
Obtain the back-up time according to "4-1 Measuring method of the backup time" on page 36.
If the measured value is half of the "initial value of the backup time," the battery needs replacing.
3. Guideline and frequency for checking the battery (measuring the backup time)
Ambient temperature
20°C

5-2 Replacing the battery

You can replace the battery of the UPS by yourself.
Battery replacement for the UPS can be done under usual operating conditions (when power is
being output). The battery can also be replaced while the UPS is off (no power is being output). You
can choose either of the methods, whichever is more convenient.
* When replacing the battery during operation, if a power failure or other failures occur while the
battery is not connected, the UPS will shut down without going into Battery mode.
If there is liquid coming from the replaced battery pack, do not touch it.
● If touched, the liquid (dilute sulfuric acid) may cause burn injury or blindness.
When replacing the battery, do not insert anything metal into the battery.
● An electric shock or short may occur.
