The SINEC L2 bus cable must satisfy the requirements laid down in
Section 5.3.
Connect the SINEC L2 bus cable to the RS 485 repeater as follows:
1. Cut the SINEC L2 bus cable to length.
2. Strip the ends of the SINEC L2 bus cable as shown in Fig. 6-10.
Fold back the braided shield over the end of the cable sheath. This is
necessary to ensure that the shield clamp can function as strain relief and
as a terminal for the shield.

Connect the same conductor (green/red for SINEC L2 bus cable) to the
same connections, A or B (e.g., always connect the green conductor to
terminal A and the red conductor to terminal B).
4. Tighten the shield clamps so that the naked shield is held firmly by the
clamp.
