8. Maintenance
With a minimal amount of maintenance, you can expect the UPS to have a long life free of trouble. The most
critical issues for the reliability of the UPS are environmental issues. Ensure that the temperature and
humidity are always according to specifications and keep the area around the unit clean and dust free.
At a temperature of 25°C, the typical battery lifetime is 4 years.
Also check at regular intervals of 6 to 12 months whether the back-up time of the battery is adequate.
8.1 Replacing batteries
The batteries may be replaced without having to turn the UPS off or disconnecting the load due to the
hot-swappable battery feature.
WARNING!
Batteries may cause electrical shock or burn from high short circuit currents. Please observe the
following precautions: 1. Remove jewelry and metal objects such as watches and rings. 2. Use
tools that have insulated handles. 3. Keep tools and other metal objects from contacting and
away from the batteries.
ELECTRIC ENERGY HAZARD. Do not attempt to rewire, alter, or change any battery wiring or
connectors. Attempting to make such alterations can cause injury.
Replace the batteries with the same number and type as originally installed batteries.
DO NOT DISCONNECT the batteries while UPS is in Battery mode.
