C A U T I O N
The Extended Battery Module (EBM) is heavy (see page 61). A minimum of two people are required to lift the EBM when it is replaced.
To replace the Extended Battery Modules (EBMs):
1.Unplug the EBM cable from the UPS.
NOTE For 230V models, remove the fixed cover plate, and then unplug the EBM cable from the UPS.
If additional EBMs are installed, unplug the EBM cable from the battery connector on each EBM.
2.If the EBM is in a tower configuration, remove the joining brackets.
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.
5.Replace the EBM. See “Recycling the Used Battery or UPS” on page 57 for proper disposal.
6.Reinstall the pedestals if removed in Step 3.
7.Reinstall the joining brackets if removed in Step 2.
8.Plug the EBM cable(s) into the battery connectors as shown in Figure 45.
For E/EH UPS models, remove the cover from the EBM cable and plug the EBM cable into the UPS. Attach the fixed cover plate to the EBM cable.
9.For additional EBMs, plug the EBM cable into the battery connector on the adjacent EBM.
For E/EH UPS models, remove the EBM battery connector cover. Remove the cover from the EBM cable of the second cabinet and plug the EBM cable into the battery connector on the first EBM.
