III. ELECTRICAL SYSTEMS
Safety and operating instructions for the electrical system
WARNING
Improper use of the DC and/or AC systems may give rise to fire or explosion hazards.
Improper use of the AC systems may give rise to electric shock hazards.
Always:
● Check the condition of the batteries (charge and electrolyte level) and the charging system
before putting to sea.
● Disconnect and remove batteries for wintering.
● Do not let battery voltage drop below 10.5 V during wintering.
● Carry spare lamps for all navigation lights and interior lighting. Respect power ratings,
particularly for navigation lights.
● Check operation of the navigational instruments.
● Check operation of navigation lights before night sailings.
You must never:
● Work on an electrical installation that is live.
● Make any modification to an installation and the relevant diagrams, unless it is carried out
by an electrician qualified in marine electrical work.
● Change or modify the breaking capacity of overload protection devices.
● Replace electrical apparatus or equipment with units exceeding the rated capacity without
uprating wiring and protection.
● Leave the boat unattended when the electrical installation is powered, with the exception
when applicable of the automatic bilge pump and the fire or theft protection circuits.
If a fuse or circuit-breaker blows continually, you should consult a specialist to determine the
cause of the short-circuit.
Fitting new equipment
Since January 1
st
1996, electrical equipment is subject to the European “electromagnetic
compatibility” directive (Ref 89/336/CEE). It is therefore necessary for any new equipment
that you may wish to install to meet the requirements of this standard and bear the CE mark.
Equipment must also be supplied with a compliance certificate and instructions for use.
In the case of 220 or 110 V installations, use only double-insulated or earthed equipment.
When such equipment is being installed, respect the fitting instructions (conductor size,
protection).
To avoid maintenance problems, make sure that any modifications that may be made to the
electrical circuit are recorded in writing in the manual.
