Determining Your ControlNet Media Requirements
Application Considerations
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 518-1982. When
planning your cable system there are certain installation
considerations depending on your application. There are three
categories of conductors:

Category:
1
Includes:
• ac power lines
• high-power digital ac I/O lines
• high-power digital dc I/O lines
• power connections (conductors) from motion drives to motors
2
• analog I/O lines and dc power lines for analog circuits
• low-power digital ac/dc I/O lines
• low-power digital I/O lines
• ControlNet communication cables
3
• low-voltage dc power lines
• communication cables to connect between system components
within the same enclosure

These guidelines apply only to noise coupling.
Intrinsic safety requirements for cable mounting are
of the highest priority.
