Chapter 7 Maintenance
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 21.).
7.1 Storage
For extended storage in moderate climates, the batteries should be charged for 8 hours every three months.
Repeat it every two months in high temperature locations.
1. Connect the UPS to a grounded receptacle or install the types for hard-wire connection according to
chapter 4 “Installation and Commissioning” on page 13 at an appropriate source. Switch on the input
circuit breaker at the rear of the device for hard-wired connection.
2. Pull out the mains plug after 8 hours or switch off the input circuit breaker of the UPS if hard-wired.
Then remove the connections of the UPS in an inverted sequence to what is described in chapter 4
