Scheduling of UPS and battery maintenance is normally based on the manufacturers’ recommendations. Since a UPS system is vital to the operation of critical loads, it may be considered advisable to provide more inspections than those the manufacturer recommends. Certain items on the UPS should be inspected daily or weekly.
Preventive maintenance is a systematic maintenance. The objective is to minimize equipment operating problems and prevent failures by making minor or necessary repairs before major operating difficulties occur.
The general condition of the equipment needs to be evaluated periodically, and records need to be maintained for comparison at subsequent inspections. Recorded information is more reliable than a maintenance technician’s memory.
Records should be concise but completely describe equipment conditions. Inspection records should provide complete information on the following topics, preferably on separate record sheets.
