3. ELECTRICAL SYSTEMS
3.1. Safety and operating instructions for the electrical system
WARNING
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
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 electrics.
−
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, a specialist must be consulted to
determine the origin of the short-circuit.
3.2. Installing new equipment
Since the 1
st
January 1996, electrical equipment is subject to the European
"electromagnetic compatibility" directive (Ref 89/336/CEE). Hence it is necessary to
install new equipment meeting this standard and bearing 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, be sure to mark in the manual and modifications that
may be made to the electrical diagram.
