Chapter 4 Maintenance
Using Avansys iTrust series UPS in specified ambient environment
(see Section 2.2.1) can reduce maintenance.
I. Fan
The fan is expected to be able to run for 20000~40000 hours
continuously. The higher the ambient temperature, the shorter the
fan life. During system operation, please regularly check whether all
fans are operating normally and there is air blowing out from inside.
II. Battery Maintenance
The internal battery of iTrust series UPS is sealed, lead-acid,
maintenance-free battery. The battery life depends on the ambient
temperature, charge and discharge times. High ambient
temperature and deep discharge will shorten battery life.
To ensure battery life, the battery should be maintained regularly:
Keep the ambient temperature between 15
and 25 .
To prevent small current discharge, continuous battery
discharge time exceeding 24 hours is strictly prohibited.
When the UPS hasn’t been used for a long time, and the battery
hasn’t been charged for 3 months at specified ambient
temperature, or 2 months at high ambient temperature, please
charge it for at least 12 hours.
