Perform the following steps daily:
1. Check the area surrounding the UPS system. Ensure the area is not cluttered, allowing free access to the
unit.

cabinet) are not blocked.
3. Ensure the operating environment is within the parameters specified in paragraph
3.2.2 Environmental and Installation Considerations and Chapter 10 Product Specifications.

the Online status indicator is not illuminated, contact an Eaton service representative.
