Electrical Connection
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).

side.
Connection Technology
You must/may use the following connection technologies when wiring the assembly:
•
Standard screw/plug connection (supply + 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
•
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.
