Replacing Batteries
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 battery: 1) Press and
hold the Off
button until the long beep ceases (approximately five
seconds), then unplug the UPS; 2) Wait 60 seconds while the internal
processor shuts down before you disconnect the battery.
Consider all warnings, cautions, and notes before replacing batteries.

current. The following precautions should be observed: 1) Remove watches, rings,
or other metal objects; 2) Use tools with insulated handles; 3) Do not lay tools or
