Siemens SIMATIC NET PROFIBUS manual Standard cable 6XV1 830-0EH10

Active Components for RS-485 Networks

Connecting the PROFIBUS Cable

Connect the PROFIBUS LAN cable to the PROFIBUS terminator, as follows:

1.Cut the PROFIBUS cable to the required length.

2.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.

e.g. standard cable
6XV1 830-0EH10
8,5	16	10

e.g. underground cable
6XV1 830-3FH10
16	16	10
8,5

Braid shield must be folded back!

3.Connect the PROFIBUS LAN cable to the PROFIBUS terminator:

Connect the same wires (green/red for the PROFIBUS LAN 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).

4.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.
