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.
