9.2 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 Normal mode (Normal status indicator is illuminated). If an
alarm lamp is illuminated or the Normal 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) and wash or replace as
necessary. See Figure 9-1 and Figure 9-2 for filter locations. The ISBM section
filter sizes are 12"
20" 0.25" and the UPM section filter sizes are
20" 44" 0.25". Contact an Eaton service representative for replacement filters.

a. Remove one top screw and two bottom screws securing each UPM section
front panel (see Figure 4-3 on page 4−4). Lift the panel straight up to remove
it from the panel hanger bracket at the top of the cabinet.

front panel (see Figure 4-2 on page 4−3). Lift the panel straight up to remove
it from the panel hanger bracket at the top of the cabinet.
