Eaton Breaker Panel Introduction • 1
1Introduction
E2can communicatedirectly withEaton'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.
1.1. 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.
1.2. 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.

2 Wiring
2.1. BCB Wiring
Two four-pin combination LAN/Power Connec-
tors are located on each BCB (Figure 2-1). It also has
the “Breaker Terminations” for plugging into the
Eaton Breaker Panel and the “LAN Address Switch-
es” used to set the MODBUS address (1 to 8) for com-
munication with E2. Three recessed LEDs (RUN,
LAN, PWR) are located on the BCB that indicate the
communication and power status of the BCB.
2.1.1. LAN/Power Connectors
A 24VAC transformer is needed to power the BCB
modules (see Table 2-1). One 75VA transformer can
power up to four panels, eight BCB modules, if they
are in the same area, or one 75VA transformer can be
used per panel.
The secondary leads of the 24 VAC transformer
should have one wire connected to the 24 V terminal
of the BCB modules, and the other secondary wire
connected to the 24 Com terminal of the BCB mod-
ules. The side of the 24VAC secondary connected to
the 24 Com terminals of the BCB should also be con-
nected to the chassis ground/earth bus of the panel.
It is recommended to use 16 AWG wire with 600
V isolation jacket for interconnecting BCB modules
24VAC power with a maximum length of 150 feet. If
the BCB modules are mounted in closer proximity
such that the total power length is 50 feet or less, then
18 AWG conductors may be substituted.
2.2. Power ON Indicators
2.2.1. BCB Status LEDs
Once power is applied to the Eaton Breaker Panel
and each connected BCB, the “PWR” (Power) LED
on each BCB should be illuminated red. If the Power
LED does not illuminate, verify the power supply and
theproper wiringterminations on eachBCB. Confirm
all four-pin connectors are properly wired.
PWR
The PWR LED is illuminated ON solid when the
BCB is powered up (24VAC). If the PWR LED is
OFF, the other LEDs will be OFF. Verify that the cir-
cuit breaker is functional and check wiring to ensure
that the BCB is receiving power.

TheLANLEDblinks(one-secondintervals)when
the E2 is communicating with the BCB and the BCB
is receiving data. If the LAN LED is not blinking or is
non-functional, verify the PWR LED is ON and the
power wiring is correct (no crossed wires and no wir-
ing connections that have shorted out).
RUN
The RUN LED blinks (one-second intervals)
when the BCB is wired correctly and communicating
with the E2. If the RUN LED blinks twice consecu-
tively and turns OFF for three seconds, this indicates
that the BCB is not communicating properly.
2.2.2. BCB Network Termination
Use Retail Solutions standard third-party termina-
tion:
• Terminate at E2 with all three jumpers at one end of
the network.
• At the other end of the network, terminate at the last
BCB module with 150 ohm resistor or CPC P/N
537-2711 MODBUS Termination Block.
• Standard Belden #8761 RS485 I/O Net cable recom-
mended.

3.1. Eaton Breaker Panel System
The relationship between the E2 and the Eaton
PanelBreaker can beseeninFigure 3-1. The diagram
shows four Eaton Breaker Panels with two BCB mod-
ulesper panelwith a maximumof eight BCBmodules
allowed per MODBUS port.
If the panel contains a single rail or only one BCB
module per panel, up to eight panels can be controlled
by an E2.
3.2. Breaker Control Bus Address-
ing
Assigna unique address foreach BCB on theLAN
address switches before the E2 can communicate reli-
ably. In the case of a two-rail panel, each rail has a
separate MODBUS physical address used for com-
munication: the physical address of the first rail will
be the device address visible to the user in Network
Services. The physical address of the second rail is
determined by taking the address of the first rail and
adding one. Always set the left rail as an odd number
and the right rail as an even number (odd + 1 or left
rail + 1) in order for it to display correctly in the E2.
For example, if the physical address of panel 1 is
1, (left rail = 1, right rail = 2), you will see the address
of the left rail in the Network Summary screen. In
Figure 3-1, the odd panel numbers 1,3,5, and 7 will
be visible on the Network Summary screen.

CAUTION! The same BCB model is used
for both Left and Right rails - there are
not separate BCB models for each rail. In
Figure 1-2, the BCB module for the Right rail is
mounted upside down from the Left rail, therefore
the address switch numbering and ON/OFF posi-
tions are reversed for Left and Right rail BCB
modules. Check the labeling on each BCB module
for the correct address switch numbering and
ON/OFF positions.

Network Connection to E2 using MODBUS Networking • 5
3.3. Network Connection to E2 us-
ing MODBUS
3.3.1. COM Port Associations - E2 Ver-
sions 3.xx and Below
Connecting an Eaton Breaker Panel to an E2 unit
using MODBUS requires the E2 to be version 2.82 or
above. Contact Retail Solutions for upgrade informa-
tion if the controller is a version prior to 2.82.
An E2 has up to three COM ports that can be as-
signed for MODBUS communication (COM2, an
RS485 port on the E2 power interface board, and
COM4and COM6, which are optional ports requiring
expansioncards). COMportscan onlybe used forone
function; in other words, if COM2 is set up as the I/O
network, you cannot connect MODBUS devices to
COM2. Ensure your E2 is equipped with an RS485
COM Card (P/N 637-4890) and configured in E2
General Services (, Serial tab) to en-
able COM4 or an E2 Expansion COM Card (P/N 637-
4871) to enable COM6.
Connect the MODBUS network cable to the three-
terminal connector on the COM port you wish to as-
sign as MODBUS. Wire + on E2 to LAN - on BCBs.
Wire - on E2 to LAN + on BCBs.
3.3.2. COM Port Associations - E2 Ver-
sions 4.0 and Above
3.3.3. E2 Termination
For E2 versions 3.xx and below, if the E2 will be
the first device in the network, set the port’s termina-
tion jumpers to the TERMINATED & BIASED posi-
tion (all three jumpers UP); otherwise, set all jumpers
DOWN if not the first device.
For E2 versions 4.0 and above, if the E2 is the be-
ginning of all RS485 I/O or MODBUS Networks, all
three of these jumpers should be set to the UP posi-
tion. For MODBUS, the jumpers should all be in the
top-most position (MOD). For I/O Net, the jumpers
should be in the middle position (I/O). For no termi-
nation, set the jumpers to the down position (NO).

5 Troubleshooting
5.1. Troubleshooting Eaton Break-
er Panels and the MODBUS
Network
Problem: Eaton Breaker Panel is Offline
1. Check Wiring - Verify the Eaton Breaker
Panel is properly connected to the MODBUS
cable. Verify the network polarity is correct
(MODBUS 485+ to BCB LAN- terminal,
MODBUS 485- to BCB LAN+ terminal) and
there are no loose wires. If none of the Eaton
Breaker Panels are online, check wiring con-
nections on the E2. Check the cable jackets to
make sure all network cable is Belden #8761
or equivalent.
2. Verify MODBUS Port Setup - Press +
on the E2 front panel. Verify COM2, COM4,
or COM6 is set up as a MODBUS port. If so,
verify that the MODBUS cable is connected
to the proper connectors. Verify the COM
port fields (Figure 3-8) are properly set for
ECT MODBUS (9600 baud, data size=8 bits,
Parity=NONE, stop bits=1).
3. Check Eaton Breaker Panel Selector Num-
bering - Verify that the selector matches the
“address selector” parameter under the De-
vices tab in E2.
4. Check Network Termination - The two de-
vices on either end of the MODBUS network
should be terminated, with all other devices
in the daisy chain unterminated. Check jump-
er settings for all devices on the network.
5. Verify BCB power connections - It is im-
portant to observe proper orientation of
the BCB to facilitate both physical place-
ment and logical performance. The BCB
alsohasthreestatus LEDs used toindicate
its activity and operation. Refer to Section
2.2.1. BCB Status LEDs.
5.2. Panels with UNSUPPORTED
