Modbus TCP Card
Installation Guide Ground Fault Protection
8 Ground Fault Protection
8.1 Overview
N O T I C E
Ground fault protection is only available on ground fault enabled option cards with soft starters running a compatible version of software. Contact the supplier for assistance.
The Modbus TCP Card can detect ground current and trip before the equipment is damaged.
Ground fault protection requires a 1000:1 or 2000:1 current transformer (not supplied). The CT should be rated 1 VA or 5 VA. The soft starter can be configured to trip at 1–50 A. If ground fault current rises above 50 A, the soft starter trips immediately.
Parameter 40-3 Ground Fault Trip Active selects when ground fault protection is active.
8.2 Connect the CT to the Ground Fault Inputs
To use ground fault protection, a common-mode current transformer (CT) must be installed around all 3 phases.
Procedure
1.
2.
Use a 1000:1 or 2000:1 CT with a rating of 1 VA or 5 VA.
Set parameter 40-5 Ground Fault CT ratio to match the CT.
3.
Connect the CT to the ground fault terminals (G1, G2, G3).
For maximum protection, the CT should be installed on the input side of the soft starter.
8.3 Configure Ground Fault Protection Settings
Ground fault protection settings must be set in the soft starter.
Parameter Description
Parameter 40-1 Ground Fault Level
Parameter 40-2 Ground Fault Delay
Sets the trip point for ground fault protection.
Shows the response of the Modbus TCP Card to ground fault variation, avoiding trips due to momentary fluctuations.
Parameter 40-3 Ground Fault Trip Active Selects when a ground fault trip can occur.
Parameter 40-4 Ground Fault Action Selects the response of the soft starter to the protection event.
Parameter 40-5 Ground Fault CT Ratio Set to match the ratio of the ground current measuring CT.

Modbus TCP Card
Installation Guide
9 Network Design
9.1 Star Topology
In a star network, all controllers and devices connect to a central network switch.
Network Design
Illustration 3: Example of Star Topology
9.2 Line Topology
In a line network, the controller connects directly to 1 port of the 1 st card. The 2 nd Ethernet port connects to another card, which in turn connects to another device until all devices are connected.
Illustration 4: Example of Line Topology
N O T I C E
The device has an integrated switch to allow data to pass through in line topology. The device must be receiving control power from the soft starter for the switch to operate.
N O T I C E
If the connection between 2 devices is interrupted, the controller cannot communicate with devices after the interruption point.

Installation Guide Network Design
N O T I C E
Each connection adds a delay to the communication with the next device. The maximum number of devices in a line network is
32. Exceeding this number may reduce the reliability of the network.
9.3 Ring Topology
In a ring topology network, the controller connects to the 1 st card via a network switch. The 2 nd Ethernet port of the card connects to another device, which in turn connects to another device until all devices are connected. The final device connects back to the switch.
The device supports beacon-based ring node configuration.
Illustration 5: Example of Ring Topology
N O T I C E
The network switch must support loss of line detection.
9.4 Combined Topologies
A single network can include both star and line components.
