Electrical Noise Reduction

This section outlines best practices that minimize the possibility of noise-related
failures as they apply specifically to Kinetix 6200 and Kinetix 6500 system
installations. For more information on the concept of high-frequency (HF)
bonding, the ground plane principle, and electrical noise reduction, refer to the

Bonding Modules

Bonding is the practice of connecting metal chassis, assemblies, frames, shields,
and enclosures to reduce the effects of electromagnetic interference (EMI).

Unless specified, most paints are not conductive and act as insulators. To achieve
a good bond between power rail and the subpanel, surfaces need to be paint-free
or plated. Bonding metal surfaces creates a low-impedance return path for high-
frequency energy.

Improper bonding of metal surfaces blocks the direct return path and allows
high-frequency energy to travel elsewhere in the cabinet. Excessive high-
frequency energy can effect the operation of other microprocessor controlled
equipment.

IMPORTANT

To improve the bond between the power rail and subpanel, construct your
subpanel out of zinc plated (paint-free) steel.
