7.2 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.
Majority of the work must be performed by Eaton authorized service personnel. Only the actions
described in
Chapter 7.2.1 DAILY maintenance on page 73 and Chapter 7.2.2 MONTHLY
maintenance on page 73 are allowed for the user.
7.2.1 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 (the back of the UPS
cabinet sections) are not blocked.
3.
Ensure the operating environment is within the parameters specified in Chapter 3.2.1
Environmental and installation considerations on page 25 and Chapter 8 Technical data on page
76.
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.
7.2.2 MONTHLY maintenance
Perform the following steps monthly:
1.
Monitor system parameters on the control panel ( Chapter 6.2 Steps to operate the UPS on page
61).
2. If the optional air filters are installed, check them (located behind the front doors) and wash or
replace as necessary. Contact your service representative for replacement filters. To replace the
filters:
a. Open the front door latch and swing the doors open.
b. Replace the filters.
c. Close the doors and secure the latch.
3. Record the check results and any corrective actions in a suitable log.
7.2.3 PERIODIC maintenance
Periodic inspections of the UPS should be made to determine if components, wiring, and connections
exhibit evidence of overheating. Particular attention should be given to bolted connections.
Maintenance procedures should specify that the bolted connections be re-torqued.
