Installing BDU
6.9 Grounding Stud
The BDU should be grounded. Use a heavy ground cable (Not supplied) to connect the BDU to the vessel’s
ground during normal use. A safety grounding system is necessary to protect your radio hardware from
lightning strikes and the build-up of static electricity. The grounding system must comply with the safety
standards that apply in your country.
Ground the BDU using a heavy ground cable (not included) from the Grounding Stud of the BDU back
panel to the vessel’s ground to protect the system from unwanted surges and voltage differentials.
