Connecting the CH Breaker
Gateway to the Breaker Pan-
els

The Cutler-Hammer breaker panels connect to the

Gateway by MODBUS network connection. MODBUS is

a two-wire, polarity-sensitive network physically similar to
RS485. Using shielded, two-conductor 22AWG wire

(Belden #8761 or equivalent), connect all panels in a single

daisy-chain network configuration leading from the Gate-
way to each of the breaker panels in series.

Figure 4-1

shows how to connect the wires to the

MODBUS connectors.

IMPORTANT!

The polarity of the PRC100MOD con-

nectors is the opposite of the Gateway board’s connector.

The wire color connected to the positive (+) terminal of the
Gateway board should be wired to the negative (-) terminal

on the breaker panels, and vice-versa.

4.1.1. Terminating the MODBUS Net-

work

The two devices at the ends of the MODBUS network

must be terminated. If the Gateway board is one of the end

devices, terminate the network using the three termination

jumpers located next to the Gateway MODBUS Connector

(

Figure 4-2

). PRC100MOD boards have no on-board ter-

mination and must be terminated with a 150-ohm resistor
across the + and - terminals

(Figure 4-2)

4.1.2. Setting the PRC100MOD Address

The PRC100MOD controllers on the Cutler-Hammer

breaker panels have a switch used to set the MODBUS ad-

dress. This switch must be used to give each PRC100MOD
a unique address from 1 through 4.

Figure 4-3

shows the

switch location and positions for each MODBUS address.
