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 o C.
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 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.
