Grounding Your 1394 System We recommend that all equipment and components of a machine or
process system have a common earth ground point connected to their
chassis. A grounded system provides a safety ground path for short
circuit protection. Grounding your modules and panels minimizes
shock hazards to personnel and damage to equipment caused by short
circuits, transient overvoltages, and accidental connection of
energized conductors to the equipment chassis.
Grounding your System to the Subpanel
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 system and axis modules. Refer
to Appendix B for interconnect information.
