Installing a New Battery Pack
To install a new battery pack, reverse the steps in “Removing the Battery Pack,” in this
chapter.
Testing the New Battery Pack
After installing the new battery pack, press the Test/Alarm Reset button. For information on
initiating a self-test, refer to the section, “Initiating a Self-Test,” in Chapter 2.
IMPORTANT:
The UPS does not execute a self-test until the batteries are 90 percent charged.
If the installation has been successful, the Bad Battery/Low Battery LED and the Bad Battery
LED are not illuminated.
If the installation has not been successful, an audible alarm may sound, the On Battery/Low
Battery LED illuminates solid amber, and the Bad Battery LED flashes red. If this occurs,
remove and reinstall the battery pack, and check the battery terminal connections. If both
LEDs remain in the alarm condition, refer to Chapter 5, “Troubleshooting,” for more
information on the cause of the alarm.
IMPORTANT:
The batteries charge to 90 percent of their capacity within less than 3 hours. Allow 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 24 hours.
