Operation and Maintenance Tips

Tip No. 1

UPS manufacturers often propose a regular maintenance schedule to maintain performance. The battery requires special attention, as UPS failure is often caused by a battery-related problem and not by the UPS's electronics.

Tip No. 2

Make sure that ventilation keeps the equipment at the operating temperature range specified by the manufacturer. Install dedicated air conditioning if necessary.

Tip No. 3

Periodically compare the load and type of load with the UPS specification to make sure the system is still able to meet changes in demand.

Tip No. 4

Standby (offline) UPSs have an automated switching system that brings the UPS online. Periodically test the switching system.
