System Grounding - GE VersaMax Manual

System Grounding

All components of a control system and the devices it controls must be properly grounded.
Ground conductors should be connected in a star fashion, with all branches routed to a
central earth ground point as shown below. This ensures that no ground conductor carries
current from any other branch.

Device
The control panel and enclosure should also be bonded to the plant system ground per
code. Inadequate grounding may compromise system integrity in the presence of power
switching transients and surges.
