Installing the Shield Contact Element
Install the shield contact element as follows:
1. Push the two bolts of the fixing bracket into the guide on the underside of the
rail. Position the fixing bracket under the modules to be wired.
2. Bolt the fixing bracket tight to the rail.
3. A slotted web is arranged at the bottom side of the terminal element. Place the
shield terminal at this position onto the edge of the fixing bracket (see
Figure 5-8). Press the shield terminals down and swing them into the desired
position.
You can attach up to four terminal elements on each of the two rows of the
shield contact element.
Shield must lie under the shield terminal

Attaching Cables
You can only attach one or two shielded cables per shield terminal (see Figure 5-8
and Table 5-6). The cable is connected by its bare cable shield. There must be at
least 20 mm of bare cable shield. If you need more than 4 shield terminals, start
wiring at the rear row of the shield contact element.
Note
Use a sufficiently long cable between the shield terminal and the front connector.
This enables you to remove the front connector without removing the shield
terminal.
