2.2.15.6 Cabinets, Internal Cables
2.2.15.7 External Cables
When you are selecting suitable cables to use and when the cables are placed in the plant,
be aware that there are some restrictions and rules to be followed which involve, among other
things:
• The distance between Advant OCS cables and non-Advant OCS cables.
• The routing of communication cables.
• Mixing of signals and signal types within cables.
• The need for shielded cables.
See the electrical installation rules given in the sections above and the general document
Interference-Free Electronics Design and Applications, which also gives examples of the
available cables.
