9.2Performing 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.

9.2.1DAILY 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,

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.

9.2.2MONTHLY Maintenance

Perform the following steps monthly:

1.Monitor system parameters as described in paragraph 7.2, Panel" on page 3−1.

2.Check the UPS air filters (located behind the front panels) and wash or replace as necessary. See Figure 9-1and Figure 9-2for 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. To remove the filters:

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