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.

batteries.

The EBM is heavy (54.9 kg/121 lb). A minimum of two people are required to lift the cabinet
into the rack.
To replace the EBMs:
1.
Switch all battery circuit breakers to the OFF (O) position (see
Figure 11).
2.
Unplug the EBM cable from the UPS.
If additional EBMs are installed, unplug the EBM cable from the
battery connector on each EBM.
3.
If the EBM is in a tower configuration, remove the joining brackets.
4.
If the EBM has pedestals installed, remove the pedestals and
retain.
5.
If the EBM is in a rack, attach the supplied mounting handles to the
mounting brackets on the new EBM.
6.
Replace the EBM. See “Recycling the Used Battery or UPS” on
page 24 for proper disposal.
