NOTE DO NOT DISCONNECT the batteries while the UPS is in Battery mode.

Consider all warnings, cautions, and notes before replacing batteries.

W A R N I N G

: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.

NOTE An EBM charges to 90% capacity in approximately 3 hours. However, it is recommended that the batteries charge for 24 hours after installation or long-term storage.

NOTE If more than two EBMs are installed, an external battery charger is recommended for faster recharge times.

Use the following procedure to replace EBMs:

1.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 UPS is in a tower configuration, remove the EBM brackets.

3.If the UPS is in a rack, install the mounting handles and brackets on the new EBM.

4.Replace the EBM. See “Recycling the Used Battery” on page 18 for proper disposal.

5.Reinstall the EBM brackets if removed in Step 2.

6.Plug the new EBM into the UPS as shown in Figure 7.

For additional EBMs, plug the EBM cable into the battery connector on the adjacent EBM.
