When to Replace Batteries
When the indicator flashes, the batteries may need replacing.
Conduct a self-test by pressing and holding the button for three
seconds. After the test is complete, the indicator should turn off (it
may take a few seconds to turn off). If the indicator continues to
flash, contact your service representative to order new batteries.
How to Replace Extended Battery Modules
NOTE DO NOT DISCONNECT the batteries while the UPS is in Battery mode.
With the hot-swappable battery feature, UPS batteries can be replaced
easily without turning the UPS off or disconnecting the load.
If you prefer to remove input power to change the batteries, see
“Turning the UPS Off” in the UPS user’s guide.
Consider all warnings, cautions, and notes before replacing batteries.
