Connecting The Cable Using Push-In Terminals - Siemens Simatic CFU Commissioning Manual

Connecting
7.5 Connect cables for sensors, actuators and power supply to the connector
Note
Ferrules
You can achieve optimum results with respect to a high-quality and durable electrical
connection with maximum conductor extraction forces through the use of crimp shapes,
preferably with smooth surfaces, as is ensured for example with rectangular and trapezoidal
crimp cross-sections.
Due to the variety of crimp shapes used in industry, we recommend other shapes on request.
Crimping dies with a pronounced wave profile are unsuitable.
7.5.3

Connecting the cable using push-in terminals

Note
Cable cross-sections
With small conductor cross-sections and stranded cables, there is a risk that the cable will be
bent when it is plugged into the terminal.
Recommendation
Use wire end ferrules to prevent contact problems or short circuits.
You can find information on preparing the cables in section "Cable cross-sections and wire
end ferrules (Page 45)".
Connecting the cable
Procedure
1. Prepare the cables.
2. In case of a stranded wire without wire end ferrule:
Press the screwdriver against the spring release.
The spring bracket opens.
3. Insert the wire into the round opening as far as it will go.
4. In case of a stranded wire without wire end ferrule:
Remove the screwdriver from the spring release.
Result
