6.Carry out a thorough examination of the UPS power components and sub-assemblies, paying particular attention to the following -

Electrolytic capacitors - Check for signs of leakage, buckling etc.

Magnetic components - Check for signs of overheating, security of fixture and signs of delamination.

Cables and Connections - Check cables for chaffing, fraying or signs of overheating. Check that all printed circuit board connectors are secure.

Printed circuit boards - Check the cleanliness and integrity of the circuit boards and replace if any signs of deterioration are found.

7.Thoroughly clean inside the equipment enclosure using a vacuum cleaner and low pressure air to remove any foreign debris.

8.Reconnect the UPS input mains power.

9.Start the UPS and transfer the load to the inverter following the appropriate operating procedure.

1.If possible, check the battery autonomy time by opening the input isolator (I1) with the UPS on-load. Close the input isolator immediately the DC busbar voltage falls to 325V (note that at 320V the battery circuit breaker will trip and the load will transfer to bypass). Ensure that the available battery autonomy time meets the installation specifications.

We recommend that ALL the input/output power cables and their connections are checked periodically. As this requires the UPS to be completely shut down such a check should be carried out on an ‘opportunity’ basis but at an interval not exceeding 2 years.

The batteries used with the UPS are generally of a sealed, valve- regulated type, and the only maintenance requirement is to ensure that the cells are kept clean and dry. Maintenance procedures appropriate to both, valve-regulated and un-sealed batteries vary, and should be obtained from the battery manufacturer.
