Introduction

E2 can communicate directly with Eaton's Breaker
Control Bus (BCB) modules (Eaton Breaker Panel).
Communication with the E2 will enable the user to
use features such as Time Schedules, Enhanced
Lighting, and Logging. In addition, the user will gain
the added capabilities of dial-out on failure and off-
site remote connection, specifically with UltraSite32
and Site Manager to the breaker panel.
The Eaton Breaker Panel controller is a licensed
application available in the E2 300 and 400 model
controllers with a maximum of 8 breaker panel rails
allowed.

Eaton Breaker Panel

Each Eaton Breaker Panel consists of up to a total
of 42 breakers that are divided into 2 rails (up to 21
breakers per rail), identified as breakers 1 through 42.
In addition to being identified by number, the user
will have the ability to give each breaker a unique
name.

Breaker Control Bus

The Breaker Control Bus (BCB) module is de-
signed to fit in each rail of the Eaton Breaker Panel
and provides the interface between the E2 and the re-
mote controllable breakers using MODBUS. Refer to
Figure 1-2 for proper orientation of the BCB rails.

The BCB rails attach to the Eaton Breaker Panel
interior without any special connectors or modifica-
tions.
Note how the rails are positioned (Figure 1-2) in-
side each panel. Observe the correct orientation of the
BCBs for correct breaker numbering and control with
the E2.
