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
6 months by plugging the UPS into a power outlet. The batteries charge
to 90% capacity in approximately 3 hours. However, it is recommended
that the batteries charge for 6 to 24 hours after long-term storage.
Check the battery recharge date on the shipping carton label. If the date
has expired and the batteries were never recharged, do not use the UPS.
Contact your service representative.
