Following installation, the wires and the terminal points should be labeled (see also
"Function identification and labeling" on page 5-5).
10.1.2
Shielded cables can be connected via IB IL SCN-6 SHIELD and
IB IL SCN 6-SHIELD-TWIN shield connectors. The IB IL SCN-6 SHIELD shield connector
is designed to connect one shielded cable. Two shielded cables can be easily connected
via the IB IL SCN 6-SHIELD-TWIN shield connector. In principle, cables are connected via
the shield connector in the same way as shown in Figure 10-2 on page 10-3 and Figure 10-3
on page 10-4.
Figure 10-2 shows the connection of a shielded cable using a remote bus cable as an
example. In this example, the cables are twisted pair cables.
Figure 10-3 shows the connection of two shielded cables, using the wiring of the
IB IL AI 2/SF-PAC terminal as an example. As two channels can be used here, the
IB IL SCN 6-SHIELD-TWIN shield connector is used.
When connecting the cables proceed as shown in Figure 10-2 and Figure 10-3:

Figure 10-2 shows the shield connection for the IB IL SCN 6-SHIELD connector. The
procedure for the IB IL SCN 6-SHIELD-TWIN connector (shown in Figure 10-3) is the same.

Inline wiring is normally done without ferrules. However, it is possible to use ferrules. If
using ferrules, make sure they are properly crimped.
When using twisted pair cables, keep the wire twisted until just before the terminal point.
For the connector pin assignment, please refer to the corresponding terminal-specific
data sheet.
Strip the outer cable sheath to the desired length (a) (detail A).
The desired length (a) depends on the connection position of the wires and whether the
wires should have a large or small amount of space between the connection point and
the shield connection.
Shorten the braided shield to 15 mm (detail A).
Fold the braided shield back over the outer sheath (detail B).
Remove the protective foil.
Strip 8 mm off the wires (detail B).
Push a screwdriver into the actuation shaft of the appropriate terminal point
(Figure 10-1 on page 10-1, detail 1), so that you can insert the wire into the spring
opening.
Phoenix Contact recommends using a SZF 1 - 0,6X3,5 screwdriver
(Order No. 12 04 51 7; see Phoenix Contact "CLIPLINE" catalog).
Insert the wire (Figure 10-1 on page 10-1, detail 2). Remove the screwdriver from the
opening. This clamps the wire.
Open the shield connection (detail C).
