Connecting the Kinetix 6000 Drive System Chapter 5
Grounding the Kinetix 6000
Drive System All equipment and components of a machine or process system should have a
common earth ground point connected to chassis. A grounded system provides a
ground path for short circuit protection. Grounding your modules and panels
minimize shock hazard to personnel and damage to equipment caused by short
circuits, transient overvoltages, and accidental connection of energized
conductors to the equipment chassis.
Ground the Power Rail to the System Subpanel
The 2094-PR x and 2094-PRS x power rail ships with a braided ground strap, 100
mm (3.9 in.), that connects to the bonded cabinet ground bus. Connect the other
end to either the power rail ground stud or mounting bracket ground stud, if
mounting brackets are used.

Instructions, publication
2094-IN003 .
ATTENTION: The National Electrical Code contains grounding
requirements, conventions, and definitions. Follow all applicable local
codes and regulations to safely ground your system.
