Winterising Your UPS: Essential Maintenance Tips

December 2023

As the mercury dips, it’s not just us who need to brace for the winter – our technology does too! One critical component that demands our attention is the Uninterruptible Power Supply (UPS). The cold season brings its own set of challenges for UPS systems. Here’s how you can ensure they continue to function reliably:


1. Battery Check-Up: The lifeblood of any UPS is its battery, and cold weather can be tough on them. Ensure they are fully charged and inspect for any signs of wear or damage. Remember, a battery's capacity can decrease in lower temperatures, so keep them in a controlled environment.

2. Environmental Controls: UPS systems are sensitive to extreme temperatures. Make sure your UPS is housed in a location with stable temperature and humidity levels to avoid condensation and frost.

3. Inspect & Secure Connections: Cold weather can cause contraction in materials. Inspect all connections and terminals to ensure they are secure and free from corrosion.

4. Firmware Updates: With the transition of seasons, it’s a good time to check if your UPS’s firmware is up to date. This ensures optimal performance and takes advantage of any recent improvements or bug fixes.

5. Plan for Power Fluctuations: Winter storms can cause power fluctuations and outages. Ensure your UPS is set up to handle these with appropriate settings and load management.

6. Professional Assessment: If possible, have a professional perform a winter-specific check-up of your UPS systems. This can help identify potential issues that could be exacerbated by cold weather.

Let’s not let the cold freeze our operations! A well-maintained UPS system is key to ensuring our businesses run smoothly, no matter what the winter throws at us.
