2.1.7 Ground circuit and protection against electrolysis
All the equipment in contact with water (pumps, engines, pipes, transmission, propeller,
toilets, …) are connected together to make a circuit, isolated from the other wires but linked
to the zinc anodes of the rudder.
This installation (green / yellow wire) represents a protection against the electrolysis :
anodes break up, but not the item being protected.
Warning : inspect anodes every 6 months.
Change anodes every year, maybe more often. Electrolysis depends on the environment of
the boat, ands especially if there is a metal boat close-by.
The Super Maramu 2000 has got in standard 2 ground plates on the rudder, used by the
SSB system.
If the boat hasn’t got any SSB, these plates are connected to the zinc anodes.
When setting up a SSB, disconnect ground plates of the anodes (behind the chart table).
When a new metallic material in contact with water is installed :
-
be sure the alimentation wires (positive and negative) are isolated,
-
link the metallic part to the ground circuit.
