Performing Preventive Maintenance
The UPS system requires very little preventive maintenance. However, the system
should be inspected periodically to verify that the units are operating normally and that
the batteries are in good condition.
9.2.1
DAILY Maintenance
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.
2.
Ensure the air intakes (vents on the front door or panels) and the exhaust
openings (on top of the UPM section) are not blocked.
3.
Ensure the operating environment is within the parameters specified in
paragraph 3.2.1 on page 3-1 and Chapter 10, “Product Specifications.”
4.
Ensure the UPS is in Online mode (Online status indicator is illuminated). If an
alarm lamp is illuminated or the Online status indicator is not illuminated, contact
an Eaton service representative.
9.2.2
MONTHLY Maintenance
Perform the following steps monthly:
1.
Monitor system parameters as described in paragraph 7.2, “Using the Control
Panel,” on page 3-1.
2.
Check the UPS air filters (located behind the front panels or door) and wash or
replace as necessary. See Figure 9‐1 or Figure 9‐2 and Figure 9‐3 or Figure 9‐4 for
filter locations, and Table 9‐1 for filter sizes. Contact an Eaton service
representative for replacement filters. To remove the filters:
