4.6.1 About Remote I/O System Wiring
The raceway layout of a system reflects where the different types of
I/O modules are placed in the I/O chassis. Therefore, you should
determine the I/OĆmodule placement prior to any layout and routing
of wires. When planning your I/OĆmodule placement, however,
segregate the modules based on the conductor categories
published for each I/O module. The guidelines in this section
coincide with the guidelines for the installation of electrical
equipment to minimize electrical noise inputs to controllers from
external sources in IEEE standard 518Ć1982.
To plan a raceway layout, do the following:
D categorize conductor cables
D route conductor cables
4.6.1.1 Categorizing Conductors
Segregate all wires and cables into categories as described in the
Rockwell Automation Industrial Automation Wiring and Grounding
Guidelines, publication 1770Ć4.1. See the installation data for each
I/O module that you are using for information about its classification.
4.6.1.2 Routing Conductors
To guard against coupling noise from one conductor to another,
follow the general guidelines for routing cables described in the
Rockwell Automation Industrial Automation Wiring and Grounding
Guidelines, publication 1770Ć4.1.
You should also follow the safe grounding and wiring practices
called out in the National Electrical Code (NEC, published by the
National Fire Protection Association, in Quincy, Massachusetts) and
local electrical codes.
