Replacing the 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.
