14.3 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.
Perform the following checks 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) and exhaust opening
(on rear of the UPS cabinet) are not blocked.
3. Ensure there is at least 12 inches of clearance behind the unit for proper air
circulation.
4. Ensure the operating environment is within the parameters specified in
Chapter 15, “Product Specifications.”
5. Ensure the UPS is in Normal mode (Normal status indicator is illuminated). If
an alarm lamp is illuminated or the Normal status indicators are not illuminated,
contact Customer Support.
Perform the following checks MONTHLY:
1. Monitor system parameters as described in Chapter 8, “Using the Control
Panel.”
2. The UPS cooling air intake filter on the Powerware 9330 (10 kVA---20kVA) is
located behind the removable front panel. The UPS cooling air intake filters on
the Powerware 9330 (25 kVA---40kVA) are located behind both removable front
panels. Check the air filters and replace as necessary. The filter size is 12 in. x
12 in. x 1 in. To remove filter:
a. Remove front panel.
b. Press up on retaining clip at top of filter and remove filter.
