UPS and Battery Care

For the best preventive maintenance, keep the area around the UPS clean and dust-free. If the atmosphere is very dusty, clean the outside of the system with a vacuum cleaner.

For full battery life, keep the UPS at an ambient temperature of 25°C (77°F).

Storing the UPS and Batteries

If you store the UPS for a long period, recharge the battery every

12 months by plugging the UPS into a power outlet. The UPS charges to 90% in approximately 4 hours. However, it is recommended that the UPS charge for 24 hours after long storage.

When to Replace Batteries

When the Battery Service indicator illuminates, the batteries may need replacing (see Figure 10 on page 12). Conduct a self-test by pressing the button. If the indicator stays on, contact your service representative to order new batteries.
