Electrical connections
Unconnected connections do not comply with protection class IP65!
Water may enter the device.
To maintain the protection class IP65, assemble blanking plugs on all unconnected
connections.
The bus coupler has the following electrical connections:
X7D2 plug (5): fieldbus input
X7D1 socket (6): fieldbus output
5
X1S plug (7): 24 V DC power supply for bus coupler
Ground screw (8): functional earth
7
The tightening torque for the connection plugs and sockets is 1.5 Nm +0.5.
The tightening torque for the M4x0.7 nut (SW7) on the ground screw is 1.25 Nm +0.25.
The fieldbus input X7D2 (5) is an M12 plug, male, 5-pin, A-coded.
The fieldbus output X7D1 (6) is an M12 socket, female, 5-pin, A-coded.
See Table 6 for the pin assignments for the fieldbus connections. The view shown displays the
device connections.

1)
The supply of power to the bus coupler (UL) is via X1S (7). All lines are looped through. The bus status of V+ and V– is checked
internally.
2)
If V+ and V– have been incorrectly assigned, the LED will display a fault and the device will stay in initialization status.
Ensure that V+ and V– are assigned on the bus plug.
Danger caused by incorrectly assembled or damaged cables!
The bus coupler may be damaged.
Only use shielded and tested cables.
Faulty wiring!
Faulty wiring can lead to malfunctions as well as damage to the network.
Comply with the DeviceNet specifications.
Only a cable that meets the fieldbus specifications as well as the connection speed and
length requirements should be used.
In order to assure both the protection class and the required strain relief, the cable and plug
assembly must be done professionally and in accordance with the assembly instructions.
