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

.

TIP

Keep wire lengths as short as possible.
