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 and that the batteries are in good condition.
Perform the following checks DAILY:
·Check the area surrounding the UPS. Ensure the area is not cluttered, allowing free access to the unit.
·Ensure the air intakes (vents on the front doors) and exhaust opening
(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 Chapter 10, “Product Specifications.”
·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 5, “Using the Monitor Panel.”
·Check the air filters (located behind the front doors) and replace them as necessary. The filter size is 16 in. x 20 in. x 1 in.
·Record the results of your checks and any corrective actions in a suitable log.
