5.4 Connecting HART
1. Connect the earth conductor of the power supply to the earth terminal on the metal bracket
inside the enclosure. Adjust the cable length so that the earth conductor would be last to
disconnect if cable is pulled.
2. Tighten the cable gland and check the strain relief (pull and turn).
3. Replace the enclosure cover and hand tighten it. The sealing ring must be clean and
undamaged.
4. Tighten the screw on the cover lock.
5. Connect the external earth terminal located between the cable glands to a ground
connection at your vessel. Use a cable with a cross-section of 2.5 mm
