■ Be sure to follow the precautions listed below when handling the battery. Not
following the precautions may result in extremely hazardous conditions such as
excess heat generation, and a possible explosion of the battery.
- Do not throw the battery into fire or expose it to high temperature.
- Do not allow the connector terminals of the battery to short circuit.
- Use the battery only for RC420 Controller.

Turning ON the Controller will automatically charge the UPS battery.
It takes approximately 80 minutes to completely charge a discharged UPS battery. To
charge the battery fully, turn ON the Controller and keep it energized continuously.

10.5.3 Life Cycle of Battery

The life cycle of the battery depends on the ambient temperature, number of backup
cycles, current-carrying capacity during backup, and backup time.
To prolong the life cycle of the battery, please follow the points shown below:
- The ambient temperature of the Controller should be 5 to 30 deg.C.
Refer to the relation between the ambient temperature and the life cycle of battery as
shown below:
Suppose that the life cycle of battery is 100% when the ambient temperature is 20
deg.C.
When the ambient temperature is 30 deg.C: approximately 70%
When the ambient temperature is 40 deg.C: approximately 40%
- Do not turn OFF the power while Windows is operating.
- Keep the total current-carrying capacity of optional boards under the following range.
- Complete the shutdown of Windows within three minutes.
