6. UPS Maintenance

6.1 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 long battery life, keep the UPS at an ambient temperature
of 25°C (77°F)

6.2 Storing the UPS and Batteries

When the UPS is intended to store for a long period, recharge the battery every
6 months by connecting the UPS to utility power. The batteries charge to 90%
capacity in approximately 4 hours. However, it is recommended that the batteries
charge for 48 hours after long-term storage.

6.3 Time to Replace Batteries

When LCD backlight turns to red, the screen displays "bTWK" and there is a
continuous sounding, the battery may need to be replaced. Please check the
battery connection or contact your local dealer to order new battery.
