Ground Your Chassis

To properly ground your I/O chassis:
verify grounding configuration
install a central ground bus
connect equipment grounding conductor
connect equipment grounding conductor to ground bus
connect ground bus to grounding-electrode system
Verify Grounding Configuration
This figure shows you how to run ground connections from the chassis to the
ground bus. Two acceptable grounding methods are shown; we recommend
using a ground bus because it reduces the electrical resistance at the connection.
