Verify the Grounding Configuration
Before continuing, verify that the Protective and Functional Earth grounds are connected to
the system. We recommend that you use a ground bus to reduce the electrical resistance at the
connection.
For more information on grounding the wiring to the ControlLogix chassis, refer to the
ControlLogix Chassis–Series B Installation Instructions, publication 1756-IN080
