UPS manufacturers usually recommend that UPS maintenance should be carried out within the first year of installation, and then annually from there on out as a minimum. However, if you notice any issues with your UPS system beforehand, then you should always contact your power supply partner as soon as possible to rectify them, and to ensure that UPS repairs are carried out swiftly and efficiently. The right check up could be the difference between business continuity and costly downtime, so UPS maintenance is always worth the time and effort.
