Connecting the PROFIBUS cable
Connect the PROFIBUS cable to the PROFIBUS terminator, as follows:
● Cut the PROFIBUS cable to the required length.
● Strip the insulation from the PROFIBUS cable as shown in Figure 5-10.
The braid shield must be folded back on to the cable. Only then can the shield clamp
serve as strain relief and as the shield contact.

● Connect the PROFIBUS cable to the PROFIBUS terminator:
Connect the same wires (green/red for the PROFIBUS cable) to the same terminal A or B
(in other words always connect terminal A with a green wire and terminal B with a red
wire or vice versa).
● Tighten the shield clamps so that the shield makes good contact with the clamp.
Note
When installing the segment, make sure that no terminating resistor is activated on the
bus connectors if the two PROFIBUS terminators are included in the
PROFIBUS segment.
