System Grounding - GE VersaMax IC200PWR001 User 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. 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.
