How to Replace EBM Batteries

To replace the EBM batteries:

1.Switch all battery circuit breakers to the OFF (O) position (see Figure 13 on page 26).

2.Remove the cable retention clip and screws and unplug the EBM cable from the UPS.

If additional EBMs are installed, remove the cable retention clip and screws and unplug the EBM cable from the battery connector on each EBM.

3.Remove the EBM front cover (see Figure 14).

To remove the front cover, loosen the two front cover screws. Grasp the fingergrips on both sides of the cover and pull the cover forward firmly.

CAUTION

Pull the battery trays out onto a flat, stable surface. The battery trays are unsupported when you pull them out of the EBM.
