For the best preventive maintenance, keep the area around the equipment 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
equipment at an ambient temperature of 25°C (77°F).
If the UPS requires any type of transportation, verify that the UPS is disconnected and turned off. The batteries
are rated for a 8 year service life. The length of service life varies, depending on the frequency of usage and
ambient temperature. Batteries used beyond expected service life will often have severely reduced runtimes.

If you store the equipment for a long period, recharge the battery every 6 months by connecting the UPS to
utility power. The internal batteries charge to 90% capacity in less than 4.7 hours. However, Eaton
recommends that the batteries charge for 48 hours after long-term storage. Check the battery recharge date on
the shipping carton label. If the date has passed and the batteries were never recharged, do not use them.
Contact your service representative.
