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 the risk of electrocution.
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 bulbs 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 associated circuits, 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 the 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.
Installing new equipment
Since 1 January 1996, electrical equipment is subject to the European “electromagnetic
compatibility” directive (Ref 89/336/CEE). So new equipment being installed must meet 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, be sure to enter in the manual any modifications that may
have been made to the electrical circuits.
