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 and panel) and the exhaust opening (on top of the UPS
cabinet) are not blocked.
3. Ensure the operating environment is within the parameters specified in paragraph 3.2.2 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 LCD Control Panel”.
2. Check the UPS air filters (located behind the front panels) and wash or replace as necessary. See
Figure 9-1 for filter locations. The ISBM filter size is 12
"
x 20
"
x 0.25" and the UPM filter size is
20" x 44" x 0.25". Contact an Eaton service representative for replacement filters. To remove the filters:
a. Remove one top screw and two bottom screws securing the UPM front panel (see Figure 4-1). Lift
the panel straight up to remove it from the panel hanger bracket at the top of the cabinet.
b. Remove one top screw and two bottom screws securing the ISBM left front panel (see Figure 4-2 on
page 4-4). Lift the panel straight up to remove it from the panel hanger bracket at the top of the
cabinet.
c. Unfasten the front door latch and swing the door open (see Figure 4-2).
d. Pull the foam filters over the screw heads on the cabinet mounted studs and remove the filters from
the cabinet.
