13.2 Performing Preventive Maintenance
The UPS system requires very little preventive maintenance. However, inspect the
UPS system periodically to verify that the units are operating normally and that the
batteries are in good condition.
13.2.1 Daily Maintenance
Perform the following steps daily:
1. Check the area surrounding the UPS system. Ensure that the area is not
cluttered, allowing free access to the unit.
2. Ensure that the air intakes (vents on the front doors) and exhaust opening (on top
of the UPS cabinets) are not blocked.
3. Ensure that the operating environment is within the parameters specified in
Chapter 14, “Product Specifications,” and Drawing 164201603-2 starting on
page A-3.
4. Ensure that the UPS is in Normal mode (Normal status indicator is illuminated). If
an alarm lamp is illuminated or the Normal status indicators are not illuminated,
contact your Eaton service representative.
13.2.2 Monthly Maintenance
Perform the following steps monthly:
1. Monitor system parameters as described in Chapter 8, “Using the Control
Panel.”
2. Check the air filters (located behind the front doors) and replace them as
necessary. The left filter size is 16”
30” 1” and the right filter size is
14” 30” 1”.
To remove filters:
a. Open the front door latch and swing the doors open.
b. Slide each filter up and remove from the cabinet.
c. Slide the new filters into the brackets until seated on the bottom brackets.
d. Close the doors and secure the latch.
3. Record the results of your checks and any corrective actions in a suitable log.
13.2.3 Annual Maintenance
Annual preventive maintenance should be performed only by authorized service
personnel familiar with maintenance and servicing of the UPS system. Contact your
Eaton service representative for more information about service offerings.
