5 tips to keep your three-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network interface card, run a trial email, since sometimes changing email servers or domains can cause settings to be out of date.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. Keep service information up-to-date.
Nothing can be more frustrating than finding out your UPS is no longer under warranty after a problem arises. So review your service contract coverage and consider storing all contract information in one place, either physically or electronically. If you do not have a service contract, make sure your UPS is registered with the manufacturer, which will help you stay informed on any updates.
5. Make service information easy to find.
Find your Factory Authorized UPS and Battery Service number and keep it on file where it can be found quickly. Your Operators’ Manual should also be stored in a safe location for easy reference.
