8. Maintenance
With a minimal amount of maintenance you can expect years of satisfactory operation
from the UPS unit. The most critical issues for the reliability of the UPS are
environmental issues. Ensure that the temperature and humidity are always in
accordance with the specifications and keep the area around the unit clean and dust free.
The typical battery lifetime is 4 years when operated at 77° (25 °C).
Check the back-up time capability of the UPS/battery at 6 to 12 month intervals to
ensure adequate support for the application.
