Chapter 7 UPS Maintenance 7.1 Equipment Care 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 and then disconnect the UPS internal battery connector . 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. 7.2 Storing the Equipment 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.
