Battery use and distribution
•
All work carried out on a battery must only be carried out by someone qualified
to do so. Whenever working on a battery, wear safety goggles and protective
clothing.
•
Never smoke or produce a spark near a battery: this may cause an explosion.
•
If any acid accidentally splashes on your skin or in your eyes, rinse it off
immediately and thoroughly with fresh water. See a doctor immediately.
•
Never touch the battery terminals: you may suffer an electric shock.
•
It is essential that you disconnect the battery charger before disconnecting the
battery terminals for maintenance (either by disconnecting the AC shore power
socket or by cutting the AC circuit breaker of the battery charger).
•
Refer to the manufacturer's instructions for use and maintenance.
General points
•
The boat is equipped with a direct current electrical system.
•
The boat's electrical system comprises service batteries and the engine battery or batteries.
The service batteries serve as the power supply for all the boat's electrical components.
The "engine" battery is used only for powering the electric starter of the propulsion engine.
•
The boat may also be equipped with:
- a generator powered by its own battery;
- a bow thruster, powered by its own battery bank.
•
the batteries are charged either by a load distributor or:
- by the alternator linked to the engine when the engine is running,
- by the battery charger (where installed).
•
It is essential that a professional engineer connects the batteries when the boat is first
launched.
•
Always check the condition of the batteries and charge system before putting to sea.
•
The battery banks are isolated from one another by a charge divider (see below).
