Electrical Connection
Figure 3.2
Electrical connection
Plug X1 is located on the top side of the interface module, and plug X2 is located on the
underside.
Connection Technology
You must/may use the following connection technology when wiring the module:
■
Standard screw/plug connection ( RS)
■
9-pin D-SUB connector (CANopen 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
2
The plug-in terminal strip combines a standard screw connection and a plug connector. The
plug connector 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
electrical safety of the device.
■
Note the permissible core cross section of the conductor.
■
If you are using stranded conductors, crimp the stranded conductors with wire end
ferrules.
■
Make sure that the insulation on the conductors extends all the way to the terminal.
■
Observe the tightening torque for the screws on the terminal. The tightening torque is
0.5 Nm.
■
Using an inappropriate tool may damage the screw heads. Use a slot-head screwdriver of
size 3.5 x 0.5.
■
Connecting an alternating current can damage the device or cause the device to
malfunction. Connect the device to direct current (DC).
