Performing Preventive Maintenance
The UPS requires very little preventive maintenance. However, the UPS should be
inspected periodically to verify that the unit is operating normally.
Perform the following checks DAILY:
•
Check the area surrounding the UPS and environmental cabinet. Ensure the
area is not cluttered, allowing free access to the unit.
•
Ensure the air intakes (filters on right side of Environmental Cabinet) and
exhaust openings (on top of the UPS cabinet) are not blocked.
•
Ensure there is at least six inches of clearance behind the unit for proper air
circulation.
•
Ensure the operating environment is within the parameters specified in the
Product Specifications section of Chapter 16.
•
Ensure the UPS is in Normal mode (Normal status indicator is lit). If an alarm
lamp is lit or the Normal status indicator is not lit, contact Customer Support.
Perform the following checks MONTHLY:
•
Ensure all status indicator lamps are operative. (Press the
and
pushbuttons simultaneously to test the lamps.)
•
Monitor system parameters as described in Chapter 9, “Using the Monitor
Panel”.
•
Record the results of your checks and any corrective actions in a suitable log.
ANNUAL maintenance:
Annual preventive maintenance should be performed only by authorized service
personnel familiar with maintenance and servicing of the UPS system. Contact
your nearest field service office for more information about service offerings.
FILTER maintenance:
Pleated disposable filters, installed inside of three filter assemblies located on the
right side of the Environmental cabinet, eliminate particles from the air which is
used to cool the UPS system. Filters should be checked or replaced at least every
thirty days in a clean environment, and at least every seven days in a dirty
environment. The replaceable filter size is 20 inches x 20 inches x 1 inch with an
ASHRAE rating of 52.2. An AmAir 62 Plus meet these requirements. To remove
filters:
1.
Loosen captive screw at left side of filter grill.
2.
Open grill.
3.
Remove and replace filter.
4.
Close filter grill and secure with captive screw.
