into the UPS to avoid overheating. If necessary, use an air-gun to clean the slits and openings
to prevent any object from blocking or covering these areas.
1) Whether the UPS, LEDs, and alarm function are operating normally.
2) Whether the UPS works in bypass mode (normally, the UPS will work in normal mode). If
yes, check if any error, overload, internal fault, etc. occurs.
3) Whether battery voltage is normal. If the battery voltage is too high or too low, find the root
cause.
Battery
The HPH series UPS uses sealed lead-acid batteries. The battery life depends on the tempera-
ture, 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.
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 nor-
mally and make sure if the ventilation air can move freely around and through the UPS. If not, re-
place 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.
