Single-axis inverters have a ground jumper access door on the back of the unit.
Two captive screws secure the jumper.

All equipment and components of a machine or process system must have a
common earth-ground point that is connected to chassis. A grounded system
provides a ground path for protection against electrical shock. Grounding your
drive modules and panels minimize the shock hazard to personnel and damage
to equipment caused by short circuits, transient overvoltages, and accidental
connection of energized conductors to the equipment chassis.
ATTENTION: The National Electrical Code contains grounding requirements,
conventions, and definitions. Follow all applicable local codes and
regulations to safely ground your system.
For CE grounding requirements, refer to

Rockwell Automation Publication 2198-UM002E-EN-P - February 2018

Benefits of Correct Configuration
• UL and EMC compliance
• Reduced electrical noise
• Most stable operation
• Reduced voltage stress on components
• Helps avoid severe equipment damage
• Reduced leakage current
