Maintaining UPS safely
As a preventive or curative measure, the maintenance of UPS is a delicate phase in the lifecycle of a data centre installation, especially because the operator has to balance speed of execution with the complexity of maintenance operations.
It is essential to ensure the continuity of supply of critical loads.
After diagnosing the problem, it should be isolated and resolved safely for the rest of the installation.
The risk of error, with sometimes dramatic consequences, is greatly increased when access to certain components is particularly tricky, or if any dismantling has to be carried out inside the UPS.
Carry out work safely
To carry out maintenance work, it is recommended to use equipment with the following characteristics:
Extracting the module for maintenance outside the UPS.
Intervention on the remote module separate from the system to eliminate any risk of affecting the critical chain.
Access to all components to make maintenance work easier and more reliable.
Ensuring the quality of the work
To ensure quality, it is recommended to observe the following measures:
- Avoid dismantling operations that require work on the critical chain.
- Test the power at a full 100% before reintroducing the module.
- Eliminate any risk of spreading if there is a problem during the procedure.
- To be free from the constraints of using and installing a test load bench.

MODULYS XL modular UPS
Equipped with a patented connection system, MODULYS XL modular UPS allows you to extract a high-power module from the critical chain in less than 5 minutes to ensure safe and smooth maintenance.
Unique to the market, the "heat-run" test function certifies the module's physical and electrical operation before it is introduced into the critical chain that protects the application.
