Chloride Active and E-Series UPS User Manual 47
Chapter 16 Maintenance (E-Series)
The UPS does not require maintenance by the user. When the battery expires, the UPS or the battery must
be replaced by qualified electrical personnel.
The typical battery’s lifetime is 4 years at an ambient temperature of 25 °C. This may vary greatly depending
upon load conditions, number of outages, and environmental factors.
NOTE: Check periodically (6 to 12 months), to see whether the emergency supply time of the UPS is still
sufficient for its application (
See “Ready for Operation Check” on page 41.).

Repeat it every two months in high temperature locations.
