Installation
The Modbus® module is designed to be used in industrial
applications and installed in accordance with this
document. The device is intended for use in clean, dry
environments.
Mount the module
To mount the Modbus adapter to Motor Insight® or
C440-COM-ADP the following procedure must be
performed:
• Place the tabs opposite the Modbus connector
into the lower slots provided.
• Pivot the module on the lower tabs.
• Gently press the module and base together.

the Modbus adapter
Connect the Modbus RS-485 cable to the 5-position
connector located at the top of the module.
Connect 24 Vdc control power to the 5-position header.
The connector has screws for positive retention to
eliminate accidental unplugging
Use one wire per terminal.
Set the Modbus address, TX mode, and
baud rate
The Modbus address, TX mode, and baud rate are
set using DIP switches on the face of the module.
The Modbus address is in binary with the major units
numbered to the left of the switch on the side label.
Adding up the major units set to ON determines the
Modbus address.
Example: To set the Modbus address to 25, start from
the top (or 16) and set the switches to ON(16), ON(8),
OFF(4), OFF(2), ON(1) (16+8+1=25).
The baud rate is set using the configuration switches
B0 and B1.
Table 1. Configuration Switches
