Replacing Tower Ebms - Eaton 9130 User Manual

8. Plug the new EBM(s) into the UPS. For reference, see page 22.
Up to 1500 VA models. Connect the EBM connector from the UPS to the EBM connector on the EBM.
Press the two parts tightly together to ensure a proper connection.
2000–3000 VA models. Connect the EBM connector from the UPS to the EBM connector on the EBM.
Connect red to red, black to black, and green to green. Press the two parts tightly together to ensure a
proper connection.
All models. To connect a second EBM, unclip the EBM connector on the first EBM and pull gently to
extend the wiring to the EBM connector on the second EBM. Repeat for any additional EBMs.
9. Verify that the EBM connections are tight and that adequate bend radius and strain relief exist for each
cable.
10. Replace the EBM front cover.
To replace the cover, verify that the EBM cables are routed through the EBM cover knockouts, then slide
the cover from the left to the right until it connects with the cover hook near the left side of the EBM
cabinet. Reinstall the two screws on the right side of the front cover. For reference, see Figure 27 on
page 50.
Repeat for each additional EBM.
11. Verify that all wiring connecting the UPS and EBM(s) is installed behind the front covers and is
inaccessible to users.

Replacing Tower EBMs

The EBM is heavy (see page 56). Lifting the cabinet requires a minimum of two people.
To replace the 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. Replace the EBM(s). See "Recycling the Used Battery or UPS" on page 52 for proper disposal.
3. For each replaced EBM, remove the cable retention clip covering the battery connector(s), as shown in
Figure 16 on page 23. Retain the clips and screws.
A small amount of arcing may occur when connecting an EBM to the UPS. This is normal and will
not harm personnel. Insert the EBM cable into the UPS battery connector quickly and firmly.
4. Plug the EBM cable(s) into the battery connector(s) as shown in Figure 16 on page 23. Up to four EBMs
may be connected to the UPS.
5. For each cable retention clip removed, rotate the clip and install it under each EBM cable connection using
the retained screws.
6. Verify that the EBM connections are tight and that adequate bend radius and strain relief exist for each
cable.
