Wiring the RS 485 Modbus Connector for Data Communication

Note: Modbus support is available only for the Conext ComBox (Part Number 865-1058), and Conext Modbus Converter (Part Number 865-1059), used with Schneider Electric Conext series inverter products.

The RS 485 Modbus connector supplied with this Conext ComBox – Freedom

SW (Part Number 809-0918), is not required for operation or supported by

Xantrex technical support.

The RS 485 Modbus connector provides three terminals to wire communication cables to the Conext ComBox. The five-terminal RS 485 connector uses the first three terminals for a data cable. The cable has a size of 16–24 AWG with

1.5 mm2–0.25 mm2 wires. The cable can be shielded or non-shielded.

To wire the RS 485 Modbus connector for data communication:

1.Select a two-wire, twisted pair, shielded cable not longer than 164 feet (50 m). Refer to the local electrical code and application to select the insulation and temperature class of the cable to be used.

2.Strip 3/8 in.(10 mm) from the end of the wires to be connected and attach ferrules to the two signal wires (red and black in the following diagram).

3.Insert the ferrules and the shield wire into the connector terminals as shown in the following diagram.

4.Secure the wires by tightening the screw on the terminal.

The middle terminal is not connected internally but is provided for the shield connection of the cable.

5.If you intend to use the Dry Contact, go to “Wiring the Dry Contact Connector”. Otherwise, go to “Wiring the Conext ComBox to an Ethernet Network”.
