Chapter 3 General Wiring Considerations
Shield-contact Plate
Connections Shielded cabling is fed in from below so that the shielding can be
connected to the shield-contact plate by using a clip. Remove about 2
cm (0.79 in.) of the outer cable insulation so that the mesh is exposed
at the point where the cable is clipped to the plate. Position the clip
over the uninsulated cable shielding and push it into the slots of the
shield contact plate until it fits firmly in place, as shown below.
Detailed Wiring
Information For detailed wiring information by product, see the table below.
To be sure that GuardPLC controllers and I/O modules are used in a
safety-related manner (SIL3 in accordance to IEC 61508), the whole
system, including connected sensors and encoders, must satisfy the
safety requirements described in the GuardPLC Controllers Safety
Reference Manual, publication
1753-RM002 .
IMPORTANT
Make sure that the mesh comes in direct contact with the
shield-contact plate. If the mesh does not touch the plate, the
cable is not grounded.
