S
Proper disposal of batteries is required. Refer to your local codes for disposal
requirements.

Do not dispose of batteries in a fire. Batteries may explode when exposed to
flame.
S
Do not open or mutilate batteries. Released electrolyte is harmful to the skin and
eyes. It may be toxic.
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 UPS cabinet) 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.

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 for filter locations. The ISBM filter sizes are
12" 20" 0.25" and the UPM filter sizes are 20" 44" 0.25". Contact an Eaton
service representative for a replacement filter. To remove the filters:
a. Remove one top screw and two bottom screws securing each UPM front
panel (see Figure 4‐1 on page 4-3). Lift each panel straight up to remove it
from the panel hanger bracket at the top of the cabinet.
b. Remove ISBM left panel.
c. Unfasten the front door latch and swing the door open (see Figure 4‐2 on
page 4-4).
d. Pull the foam filters over the screw heads on the cabinet mounted studs and
remove the filters from the cabinet.
