Electrical connection
Plug X1 is located on the top side of the interface module, and plug X2 is located on the under-
side.
Connection Technology
You must/may use the following connection technologies when wiring the assembly:
•
Standard screw/plug connection ( RS)
•
9-pin, D-SUB connector (PROFIBUS DP connection)
When using standard screw terminals, one cable per connection point can be clamped. To
tighten the screws, use a screwdriver with a blade width of 3.5 mm.
Permissible cable cross section:
•
Flexible cable with wire end ferrule: 1 x 0.25 ... 1.5 mm
2
•
Solid cable: 1 x 0.25 ... 1.5 mm

The plug-in terminal strip combines a standard screw connection and a connector. The con-
nector is coded and therefore cannot be plugged in incorrectly.
The 9-pin D-SUB connector is secured with two screws with a "4-40 UNC" thread. To tighten
the screws, use a screwdriver with a blade width of 3.5 mm. Observe the maximum tightening
torque of 0.4 Nm.
Danger!
Device damage due to incorrect installation
Incorrect installation of cables and connection lines can endanger the function and the electri-
cal safety of the device.
•
Observe the permissible core cross section of the conductor.
•
If you are using stranded conductors, crimp the stranded conductors with wire end fer-
rules.
•
Make sure that conductors are insulated all the way up to the terminal.
•
Observe the tightening torque for the screws on the terminal. The tightening torque is
0.5 Nm.
•
Using an unsuitable tool may damage the screw heads. Use a slot-head screwdriver sized
3.5 x 0.5.
•
Connecting an alternating current can damage the device or cause the device to malfunc-
tion. Connect the device to direct current (DC).
