Batteries
The DPH series UPS uses the lead-acid batteries or the lithium-ion batteries. Make sure to
replace the batteries according to battery life. However, the actual battery life depends on
the environment temperature, usage, and charging/ discharging frequency. High temperature
environments and high charging/ discharging frequency will quickly shorten the battery life; thus,
battery inspection and maintenance are required periodically. Please follow the suggestions
below to ensure normal battery life.
1. Keep usage temperature between 15°C~25°C (59°F~77°F).
2. When the UPS needs to be stored for an extended period of time, the lead-acid batteries
must be recharged once every three months and the charging time must not be less than 24
hours each time. As for the lithium-ion batteries, please contact your battery supplier for the
charging frequency and charging duration.

Fans
Higher temperatures shorten fan life. When the UPS is running, please check if all of the fans
work normally and make sure if the 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.
