8.2 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.
8.2.1 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 doors) and exhaust opening (on top of the UPS
cabinet sections) are not blocked.
3. Ensure the operating environment is within the parameters specified in paragraph 2.2.1 on
page 10 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 your service representative.
8.2.2 MONTHLY maintenance
Perform the following steps monthly:
1. Monitor system parameters as described in paragraph 5.2, “Using the Control Panel” on
page 49.
2. Check the air filters (located behind the front doors) and wash or replace as necessary. The
left (ISBM) filter size is 12”Ч20”Ч1” and the right (UPM) filter sizes are 19.5”Ч21.5”Ч0.5”.
Contact your service representative for replacement filters. To remove the filters:
a. Open the front door latch and swing the doors open.
b. Grasp foam filters and remove filters from cabinet mounted studs.
c. Push the washed or new filters onto the cabinet mounted studs until seated against
cabinet.
d. Close the doors and secure the latch.
3. Record the check results and any corrective actions in a suitable log.
8.2.3 ANNUAL maintenance
Annual preventive maintenance should be performed only by authorized service personnel
familiar with maintenance and servicing of the UPS system. Contact your service representative
for more information about service offerings.
8.2.4 BATTERY maintenance
Contact your service representative for battery maintenance. Battery replacement and
maintenance should be performed only by authorized service personnel.
8.2.5 Maintenance training
A basic training course, available from Eaton Corporation, gives you a competent working
knowledge of the UPS system operation and teaches you how to perform first level corrective
maintenance. For more information about training and other services, contact the Eaton Help
Desk for Powerware products.
