CONTROLLER GROUNDING REQUIREMENTS
NOTE – For the controller to function properly it is very important to
provide proper building ground connections to the controller.
Examples of a proper building-to-controller ground connection is
to attach the ground cable to:
The street side of the incoming water main.
To a grounding rod that has been driven into the pit flooring.
The controller has a common ground bus terminal connection.
All grounds need to land at this common point including building,
motor, transformer, and filter grounds. This prevents ground loops,
and will limit the impedance between the grounds and noise will
be channeled back to building ground.
Providing a proper ground is mandatory and will improve the
performance of the controller.
