NOTE: Terminal 3 must be connected to earth ground in each actuator for field unit surge
suppression.

NOTE: Ground each segment of the cabling at each field device unit. See Section 2.2.4.1 and
2.2.5.1. Verify the actuator is properly grounded.

7. Connect the cable shields to each other inside the unit. Do not connect them to the unit in any

way. The network shield should be grounded at the end of each segment. For surge suppression,
Terminal 3 must be tied to earth ground in both DP and PA applications.
