cause.
Battery
The HPH 20-60kVA 208V 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 charging/ discharging frequency will quickly shorten the battery life. Please
follow the suggestions below to ensure a normal battery lifetime.
1. Keep operating temperature between 59 ~ 77°F (15 ~ 25°C).
2. When the UPS needs to be stored for an extended period of time, the batteries must be
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.
