5.6Connecting the LAN Cable

All the LAN cables described in Chapter 4 are suitable for attachment to the RS-485 repeater.

Connecting the PROFIBUS Cable

Connect the PROFIBUS LAN cable to the RS-485 repeater, as follows:

1.Cut the PROFIBUS cable to the required length.

2.Strip the insulation from the PROFIBUS cable as shown in Figure 5-9.

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 cable to the RS-485 repeater:

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.
