How to Replace EBMs
C A U T I O N
The EBM is heavy (see page 112). A minimum of two people are required to lift the cabinet
into the rack.
To replace the EBMs:
1. Switch all battery circuit breakers to the OFF (O) position (see
Figure 29 on page 47).
2. Unplug the EBM cable from the UPS.
If additional EBMs are installed, unplug the EBM cable from the
battery connector on each EBM.
3. If not already installed, install the supplied mounting brackets on the
new EBM.
4. Replace the EBM. See Recycling the Used Battery or UPS" on
page 110 for proper disposal.
5. Plug the new EBM into the UPS as shown in Figure 29 on page 47.
For additional EBMs, plug the EBM cable into the battery connector
on the adjacent EBM.
6. Remove the breaker tie from the circuit breaker on all EBMs.
7. Switch all battery circuit breakers to the ON (
| ) position.
