1. If you are not using an assembled line, correctly assign your the pins for your electrical
connections (see Table 6 on page 86).
2. Connect the incoming bus line to fieldbus input X7C2 (5).
3. Connect the outgoing bus line to the next module via fieldbus output X7C1 (6).
4. Ensure that the plug housing is securely fitted to the bus coupler housing.

Electric shock due to incorrect power pack!
Danger of injury!
The units are permitted to be supplied by the following voltages only:
– 24 V DC SELV or PELV circuits, whereby each of the 24 V DC supply circuits 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 circuits which fulfill the requirements of limited-energy circuits according
to clause 9.4 of standard UL 61010-1, 3rd edition, or
– 24 V DC 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 circuits which fulfill the requirements of NEC Class II according to standard
UL 1310.
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 Table 7 for the pin assignments of the power supply. The view shown displays the device
connections.
Table 7: Power supply pin assignments
Pin X1S plug
Pin 1 24 V DC sensor/electronics power supply (UL)
Pin 2 24 V DC actuator voltage (UA)
Pin 3 0 V DC sensor/electronics power supply (UL)
Pin 4 0 V DC actuator voltage (UA)
The voltage tolerance for the electronic components is 24 V DC ±25%.
The voltage tolerance for the actuator voltage is 24 V DC ±10%.
The maximum current for both power supplies is 4 A.
The power supplies are equipped with internal electrical isolation.
