Grounding Your Kinetix 3
Drive All equipment and components of a machine or process system must have a
common earth ground point connected to their chassis. A grounded system
provides a safety ground path for short circuit protection.
For CE grounding requirements, refer to Agency Compliance in Chapter 1 .
Grounding Your System to the Subpanel
If the Kinetix 3 drive is mounted on a painted subpanel, ground to a bonded
cabinet ground bus by using a braided ground strap or 4.0 mm
2
(12 AWG) solid
copper wire 100 mm (3.9 in.) long.
Figure 28 - Connecting the Braided Ground Strap Example
IMPORTANT
Grounding your drives and panels minimizes shock hazard to personnel and
damage to equipment caused by short circuits, transient overvoltages, and
accidental connection of energized conductors to the equipment chassis.
IMPORTANT
To improve the bond between the Kinetix 3 drive and subpanel, construct your
subpanel out of zinc plated (paint-free) steel.
ATTENTION: The National Electrical Code contains grounding requirements,
conventions, and definitions. Follow all applicable local codes and regulations
to safely ground your system. Refer to the illustration below for details on
grounding your Kinetix 3 drive. Refer to
Appendix A for the power wiring
diagram for your Kinetix 3 drive.
