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, propel-

ler, 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 galvanical-

ly separated from the low tension circuit.

2. Route and clamp electric cables so that they will

not be exposed to rubbing, damp or bilge water in

the keelson.

3. The drive/reverse gear and flywheel cover are

electrically insulated (A) from the engine and must

never be used as a ground.

IMPORTANT! The drive/reverse gear and

flywheel cover must never be used as a

ground or be electrically connected to other

equipment such as the radio, navigational

equipment, the rudder, bathing steps etc.

Protective grounds for the radio, navigational

equipment, rudder, bathing steps or other

equipment with separate ground leads must be

connected to a common ground terminal (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.
