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 batteries
charge to 90% capacity in approximately 4 hours. However, it is
recommended that the batteries charge for 24 hours after long-term
storage.
When to Replace Batteries
When the Battery Service indicator illuminates, the batteries may need
replacing (see Figure 8 on page 10). Conduct a self-test by pressing the
button. If the indicator stays on, contact your service representative
to order new batteries.
