The 12 V system consists of engine driven alternators, battery chargers for shore-side electricity, batteries and equipment. The power is supplied to the batteries via diodes from either the engine alternator or the shore power charger.
To activate the circuits in the 12V system, the main switches for the corresponding circuits need to be activated and the fuses intact. When the electronic circuit is switched on, the equipment can be operated from the main switch panel.
-
Never switch off the main switch when the engine is running, because this may cause damage to the alternator.
-
Never carry out electrical installations when the power is switched on.
-
Never modify the boat’s electrical system or diagrams. Service and maintenance must be carried out by a qualified electrician.
-
Never alter or modify the rated amperage of the overcurrent protective devices.
-
Never install or replace electrical equipment with components that cause the circuit’s nominal rated amperage to be exceeded.
-
Never leave the boat unattended with the electrical system energized, except automatic bilge pump, fire protection, and alarm circuits.
-
Maintain any damaged equipment before taking it back to use.
