Grounding the ADU<br />

You can ground the ADU to the ship/hull via one or more of its<br />

mounting bolts. Make sure to remove painting, dirt, grease<br />

etc. at the mounting holes in order to make good electrical<br />

contact to the hull. Use serrated washers when securing the<br />

mounting bolts and seal the joint with protective coating to<br />

avoid corrosion.<br />
