An Uninterruptible Power Supply (UPS) is essential for protecting critical electrical and electronic equipment from power failures, voltage fluctuations, and surges.
Regular preventive maintenance ensures reliable performance, extended battery life, and uninterrupted operation during power outages.

Key UPS Maintenance Guidelines

1. Clean Regularly
Use a soft brush or air blower to remove dust and debris from the UPS unit and batteries.
Regular cleaning prevents overheating and improves airflow efficiency.

2. Inspect Electrical Connections
Ensure all cable joints and terminals are tight, corrosion-free, and meet manufacturer specifications.

3. Check for Corrosion
Inspect batteries, terminals, racks, and cabinets for any signs of rust, corrosion, or deterioration.

4. Examine for Damage
Look for cracks, leaks, or swelling in batteries and replace damaged components promptly.

5. Monitor Temperature
Keep the UPS in a well-ventilated environment with controlled temperature and humidity levels.

6. Test Performance
Perform regular tests to confirm that the UPS delivers backup power and switches automatically during outages.

7. Maintain Proper Storage Conditions
Store the UPS in a cool, dry, and dust-free area — away from sunlight, radiators, or vents.

8. Verify Grounding
Ensure proper grounding according to local electrical codes to prevent electrical hazards.

9. Stable Placement
Place the UPS on a flat, stable surface, away from heat sources, water, and vibration.
