Chapter 4 Connect the Kinetix 350 Drive System
Grounding Your Kinetix 350
Drive System
All equipment and components of a machine or process system must have a
common earth ground point that is connected to their chassis. A grounded
system provides a safety 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. For CE
grounding requirements, refer to CE Requirements
in Chapter 1.
Ground Your Drive to the System Subpanel
If the Kinetix 350 drive is mounted on a painted subpanel, ground the drive to
a bonded cabinet ground bus by using a braided ground strap or 4.0 mm
(12 AWG) solid copper wire 100 mm (3.9 in.) long.
Figure 33 - Connecting the Braided Ground Strap Example
For drive dimensions, refer to Product Dimensions in Kinetix Servo Drives
Specifications Technical Data, publication KNX-TD003
.
IMPORTANT To improve the bond between the Kinetix 350 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 ground your system safely. See the Figure 33
for details on
grounding your Kinetix 350 drive. See Appendix A
for the power wiring
diagram for your Kinetix 350 drive.
