The majority of the service and maintenance work must be done by service
personnel qualified by Eaton. Only the actions described in
Section 8.3.1 Daily
and
Section 8.3.2 Monthly maintenance
can be done by the user.
8.3.1
Daily maintenance
Do the following steps every day:
1.
Examine the area surrounding the UPS system. Make sure that the area is
not cluttered, allowing free access to the unit.
2.
Examine that the air intakes (vents on the front doors) and exhaust opening
(the back of the UPS cabinet sections) are not blocked.
3.
Make sure that the operating environment is within the parameters specified
in
Sections 4.4.1 Environmental considerations
and
and
Chapter 9.1 About technical data
.
4.
Examine that the UPS is in the normal operation mode (the green status
indicator for normal operation is illuminated). If the red alarm status indicator
is lit or the green status indicator for normal operation is not lit, contact your
service representative.
8.3.2
Monthly maintenance
Do the following steps once a month:
1.
Examine the system parameters on the control panel (see
Section

doors) and wash or replace them, if needed. Contact your service
representative for replacement filters. To replace the filters:
a.
Open the UPS front door.

Replace the filters.
c.
Close the UPS front door.
