Connect the Kinetix 5700 Drive System Chapter 5
Ground the Drive System
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.
Ground the System Subpanel
Ground Kinetix 5700 power supplies, inverters, and accessory modules to a
bonded cabinet ground bus with a braided ground strap. Keep the braided
ground strap as short as possible for optimum bonding.
Figure 91 - Connect the Ground Terminal
Refer to the System Design for Control of Electrical Noise Reference Manual,
publication GMC-RM001
, for more information.
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 Agency Compliance
