Battery
The HPH series UPS uses sealed lead-acid batteries. The battery life depends on the temperature,
the usage, and the charging/ discharging frequency. High temperature environments and high

recharged once every three months and the charging time must not be less than 24 hours each
time.
Fan
Higher temperatures shorten fan life. When the UPS is running, please check if all fans work
normally and make sure if the ventilation air can move freely around and through the UPS. If not,
replace the fans.
NOTE:
Please ask your local dealer or customer service for more maintenance information. Do not
perform maintenance if you are not trained for it.
