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, press and
hold the Off
button for approximately three seconds, then unplug or
remove utility power from the UPS.
Consider all warnings, cautions, and notes before replacing batteries.
WARNING
: Batteries can present a risk of electrical shock or burn from high short-circuit
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
metal parts on top of batteries.
: ELECTRIC ENERGY HAZARD. Do not attempt to alter any battery wiring or
connectors. Attempting to alter wiring can cause injury.
How to Replace Extended Battery Modules

For 230V models, remove the fixed cover plate, and then
unplug the EBM cable from the UPS.

brackets from the top.
3. If the EBM has pedestals installed, remove the pedestals and
retain.
4. If the EBM is in a rack, install the mounting handles and
brackets on the new EBM.

for proper disposal.
