Testing the New Battery Module
After installing the new battery module, press the Test/Alarm Reset button. Refer to the
section, "Initiating a Self-Test," in Chapter 2 for more information on initiating a self-test.
IMPORTANT: The UPS schedules the battery test, but will not execute the test until the batteries:
•
Are at least 90 percent charged
•
Have been in float mode for 24 hours
If the installation has been successful, the Alarm LED will not be illuminated.
If the installation has not been successful, the Alarm LED turns red and the LCD menu
indicates an alarm. If this occurs, repeat the procedures in the "Replacing the Batteries"
section of this chapter, and check the battery terminal connections. If the Alarm LED is still
red, see Chapter 5, "Troubleshooting," for more information on the cause of the alarm.
IMPORTANT: The batteries will charge to 80 percent of their capacity within approximately
three hours. Compaq recommends allowing the batteries to charge for 24 hours before using the UPS
to supply backup power to devices. The load may not be fully protected for 48 hours.
