Ground
The display unit contains several CPUs. While they are operating, they radiate noise, which
can interfere with radio equipment. Ground the unit to prevent interference. The grounding
wire should be 1.25 sq or larger and as short as possible. Connect the grounding wire to
ship's ground. On a fiberglass boat, it is best to install a ground plate that measures about
20 cm by 30 cm on the outside of the hull bottom to provide a ground point. If this is not
practical, the engine block can be used.
Ground the equipment to
prevent electrical shock
and mutual interference.
CAUTION
Note: Use a “closed” lug to make the ground connection at the display unit. Do not use an
“open-type” lug ( ).
