Installation Modbus TCP Module
4.2 Soft Starter Connection
The device is powered from the soft starter.
For the soft starter to accept fieldbus commands, a link must be fitted across terminals
A1-02 on the starter.
The Modbus TCP Module is not suitable for use with compact soft starters using
380/440 VAC control voltage.

4.3 Network Connection
Ethernet Ports
The device has two Ethernet ports. If only one connection is required, either port can be
used.
Cables
Use Category 5, 5e, 6 or 6e cable to connect to the device.
EMC Precautions
To minimise electromagnetic interference, Ethernet cables should be separated from motor
and mains cables by 200 mm.
If the Ethernet cable must cross motor or mains cables, the crossing should be at an angle
of 90°.
4.4 Network Establishment
The controller must establish communications directly with each device before the device
can participate in the network.
4.5 Addressing
Each device in a network is addressed using a MAC address and an IP address.
• The device can be assigned a static IP address during configuration, or can be
configured to accept a dynamic IP address (via DHCP).
• The MAC address is fixed within the device and is printed on a label on the front of
the device.
