Electrical connections
Unconnected plugs do not comply with protection class IP65!
Water may enter the device.
To maintain the protection class IP65, assemble blanking plugs on all unconnected plugs.
The bus coupler has the following electrical connections:
X7E1 socket (5): fieldbus connection
X7E2 socket (6): fieldbus connection
5
X1S plug (7): 24 V DC power supply for bus coupler
Ground screw (8): functional earth

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 X7E1 (5) and X7E2 (6) fieldbus connections are designed as integrated M12 sockets, female,
4-pin, D-coded.
See Table 6 for the pin assignments for the fieldbus connections. The view shown displays the

The AES series bus coupler for EtherNet/IP has a 100 Mbit full duplex 2-port switch, so that several
EtherNet/IP devices can be connected in series. As a result, the controller can be connected to either
fieldbus connection X7E1 or X7E2. Both fieldbus connections are identical.
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 EtherNet//IP 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.
Never connect the two fieldbus connections X7E1 and X7E2 to the same switch/hub.
Make sure that you do not create a ring topology without a ring master.
