Grounding Analog I/O Lines
Overview

Analog wires must be grounded directly when entering the cabinet. You may use commercial cleats or clamps or an analog cable grounding rail. This section describes both approaches.
Principle High frequency interference can only be discharged via big surfaces and short cable lengths.
Guidelines
Follow these wiring guidelines: Use shielded, twisted-pair cabling Expose the shielding on one side (for instance, at the console exit) Make sure the track is properly grounded (seepage186) Grounding of the bus cable is determined by the bus adapter used. Look for details in your bus adapter manual .
Using Cleats or Clamps Cleats or clamps can be mounted directly on the ground rail (PE/FE rail) in the cabinet, as shown in the illustration below. Be sure the cleats or clamps make proper contact.
