5 tips to keep your single-phase UPS healthy year-round

Ensuring the ongoing optimal performance of your uninterruptible power system (UPS) requires just a few minutes of your time --- but can be critical to avoiding unexpected downtime. Just like an annual visit to your physician’s office will help identify any potential health concerns, your UPS should receive a yearly check-up, as well. The following checklist will help you get a pulse on how your UPS is feeling.
1. Make sure your batteries are in good health.
Batteries are the No. 1 cause of UPS failure, so at least once a year, you should note their age (and plan a replacement if they are 4 years or older); run a UPS battery self-test; and remove the front bezel and make sure there are no signs of swelling or damage.
2. Perform spring cleaning.
Clutter, dust and general disorganization can cause unwanted issues and decrease the reliability of your system. Make sure nothing is blocking the air flow in your IT environment, since heat is one of the biggest reducers of battery life. Visually inspect electrical connections. And don’t forget to dust, since caked-on grime can damage fans and cause electronics board damage. A simple wipe down is often all you need.
3. Verify communication.
Properly configured UPS communications ensure that IT managers can respond to alerts and take corrective actions. If your UPS is equipped with an network interface card, run a trial email, since sometimes changing email servers or domains can cause settings to be out of date. Also check the software to be sure the UPS and network interface card both have the most up-to-date versions.
4. Make sure your UPS is registered with the manufacturer.
Proper UPS registration will help you stay informed on any updates and allows the manufacturer to respond quickly if an issue does arise.
5. Reevaluate your level of power protection.
Since your equipment and power needs may have grown since you first installed your UPS, it’s important to ensure that your unit is not operating over capacity. Advances in scalability and energy efficiency have resulted in a range of new modular UPS solutions capable of expanding with your changing needs. Consider joining a professional discussion forum or contacting a UPS manufacturer to learn more.
