12.3 Performing Preventive Maintenance

The UPS system requires very little preventive maintenance. However, the system should be inspected periodically to verity 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 bottom) and exhaust opening (on the top of the cabinet) are not blocked.

3.Ensure the operating environment is within the parameters specified in Chapter 13, “Product Specifications.”

4.Ensure the UPS is in Normal mode. (Proper LED indicators are illuminated and the LCD display shows “LOAD PROTECTED”). If the alarm LED is illuminated or the Normal status LEDs are not illuminated, contact Customer Service.

Perform the following check MONTHLY:

1.Review the Event Log for any operational issues that need attention.

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.

BATTERY Test:

The battery test takes approximately 3 minutes and should be performed only if:

There are no alarm conditions

The battery is fully charged

Utility supply is present and normal

The battery testing can be carried out independently of the operation mode (OFF-LINE or ON-LINE) and whether or not the load is connected. The battery test procedure can be performed from the UPS front panel. See Chapter 7, “Using the Control Panel”.

BATTERY Maintenance:

Contact your nearest field service office for battery maintenance. Only authorized service personnel should perform Battery replacement and maintenance.
