NOTE 1 A maximum of 22 battery strings can be installed in one configuration, including UPS
batteries (4 EBM-64 models or 3 EBM-96 models). UPS-32 models contain 2 strings;
UPS-64 models contain 4 strings; EBM-64 models contain 4 strings; and EBM-96
models contain 6 strings.
NOTE 2 For non-seismic installations, you MUST install the stabilizing bracket on all 3-high
cabinets. The stabilizing bracket is optional for 2-high cabinets.
NOTE 3 In a parallel system, each UPS should have the same number of Extended Battery
Modules (EBMs) to ensure equivalent runtimes.
To install the optional EBM:
1. Position the EBM adjacent to the next cabinet.
2. Verify that all battery circuit breakers are in the OFF position (see Figure 38).
3. Remove the two ground straps from the EBM rear panel.
4. Install one ground strap between the UPS and EBM rear panels as shown in Figure 38.
5. If additional EBMs are installed, attach another ground strap between the first and second EBM as shown
in Figure 38. Repeat for each additional EBM.
6. Plug the EBM cable into the UPS battery connector.
7. If additional EBMs are installed, plug the EBM cable of the second cabinet into the battery connector on
the first EBM. Repeat for each additional EBM.
