Maintenance: Electrical system
Electrical installations
Leakage current from the electrical system can be
caused by incorrect installation of electrical equip-
ment. Leakage current can knock out the galvanic
protection of components such as the drive, propeller,
propeller shaft, rudder stock and keel and cause
damage by electrolytic corrosion.
IMPORTANT! Work on the boat’s low tension
circuit should only be carried out by qualified or
experienced persons. Installation or work on the
shore power equipment must only be carried out
by electricians authorized to work with high-
voltage installations.
The following should always be observed:
1.
If shore power is connected, the protector ground
should be ashore, never in the boat. Shore power
should always have a ground fault circuit breaker.
Shore power units (transformer, rectifier, battery
chargers etc.) must be intended for marine usage
and the high tension circuit must be galvani-
cally separated from the low tension circuit.
2.
3.
Route and clamp electric cables so that they will
not be exposed to rubbing, damp or bilge water in
the keelson.
The S-drive is electrically isolated (A) from the
engine and must never be used as a ground.
IMPORTANT! The S-drive must never be
used as a ground or be electrically connected
to other equipment such as the radio, naviga-
tional equipment, the rudder, bathing steps
etc.
C
A
Protective grounds for the radio, navigational
equipment, rudder, bathing steps or other equip-
ment with separate ground leads must be con-
nected to a common ground terminal (B).
B
4.
There must be a main switch (C) connected to the
starter battery positive (+) terminal. The main
switch should cut off power to all power consum-
ing equipment and should be switched off when
the boat is not in use.
