Fig. 2: Electrical connections
The bus coupler has the following electrical connections:
• X7E1 socket (5): fieldbus connection
• X7E2 socket (6): fieldbus connection
• 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 (WS 7) on the ground screw is 1.25 Nm
+0.25.

Fieldbus connection

The X7E1 (5) and X7E2 (6) fieldbus connections are designed as integrated M12
sockets, female, 4-pin, D-coded.
See the table below for the pin assignment of the fieldbus connections. The
u
view shown displays the device connections. See g Table 4.

The AES series bus coupler for Ethernet POWERLINK has a 100 Mbit half-duplex 2-
port hub, so that several POWERLINK devices can be connected in series. As a re-
sult, the controller can be connected to either fieldbus connection X7E1 or X7E2.
Both fieldbus connections are identical.
Fieldbus cable
Danger caused by incorrectly assembled or damaged cables!
The bus coupler may be damaged.
Only use shielded and tested cables.

NOTICE
Faulty wiring!
Faulty wiring can lead to malfunctions as well as damage to the network.
1. Comply with the Ethernet POWERLINK specifications.
2. Only a cable that meets the fieldbus specifications as well as the connection
speed and length requirements should be used.
3. In order to assure both the protection class and the required strain relief,
cables and electrical connections must be installed professionally and in ac-
cordance with the assembly instructions.
4. Never connect the two fieldbus connections X7E1 and X7E2 to the same
hub.
5. Make sure that you do not create a ring topology without a ring master.

Power supply

Electric shock due to incorrect power pack!
Danger of injury!
1. The units are permitted to be supplied by the following voltages only:
- 24 V DC SELV or PELV power circuits, whereby each of the DC supply cir-
cuits must be provided with a DC-rated fuse which is capable of opening at
a current of 6.67 A in 120 s or less, or
- 24 V DC power circuits which fulfill the requirements of a limited-energy
circuit according to clause 9.4 of standard UL 61010-1, 3rd edition, or
- 24 V DC power circuits which fulfill the requirements of limited power
sources according to clause 2.5 of standard UL 60950-1, 2nd edition, or
- 24 V DC power circuits which fulfill the requirements of NEC Class II ac-
cording to standard UL 1310.
2. Make sure that the power supply of the power pack is always less than
300 V AC (outer conductor – neutral wire).
The X1S power supply connection (7) is an M12 plug, male, 4-pin, A-coded.
See the table below for the pin assignment of the power supply. The view
u
shown displays the device connections. See g Table 5.
