Note: Terminate the shield at the outside of the FIP cabinet (ground). Where this is not possible, the shield must be
terminated to physical ground immediately adjacent to cable entry. Between Field modules, connect shields
together outside of their respective enclosures. Make sure that the shield is only grounded at the FIP and not
at the modules or annunciators. Do not ground both ends of the shield; one end should be left floating.
