3.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.

4.Tighten the cable gland and check the strain relief (pull and turn).

5.Replace the enclosure cover and hand tighten it. The sealing ring must be clean and undamaged.

6.Tighten the screw on the cover lock.

7. 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 mm2 or greater.
