UPS MAINTENANCE
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 69.
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.

The EBM is heavy (see page 78). 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 73 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 33. 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 33. Up to four EBMs may be connected to the UPS.
