2.5 The electric installation
2.5.1 The AC-installation (230 Volt)
The yacht has got a shore connection (option) by which it can be supplied with electric power from ashore
when being berthed in a port. The plug box (meeting the CEE-norm) is installed at the starboard locker seat
of the yacht. The power is supplied into a shore connection unit, placed under the chart table.
2.5.2 The DC–board net (12 Volt)
All electric devices aboard are supplied with the 12 V DC. A main-switch is installed in the electric panel
under the chart table. Power distribution is effected by a switchboard above the chart table. The lettering next
to each switch refers to the corresponding consumer-group.
You can find all the switches for the 12 V consumers at the switchboard. By this you can operate different
consumer-groups, being marked with logos or lettering, separately. Some of the switches are designed for an
installation of additional electric devices. The motor vehicle flatconnectors are arranged on the back of the
panel.
2.5.3 Operating the installation and specific features
The combination of an AC- with a DC installation offers a clearly higher comfort but requires some special
knowledge.
Charging the batteries
All batteries are maintenance–poor and drain-protected. They are charged via a buffer diode by the motor-
generator. Charging the starter battery always takes priority to ensure a safe start of the engine.
AC–consumers
The only fixed link is the one to the battery charger. The safety contact plug-box at the electric panel is
designed for electric tools to be used for small repair work.
DC–consumers
The essential consumers are:
-
navigation lights
-bilge pumps
-
engine displays
-tank display
-
VHF-radio wiring (option)
-electronic devices
-
devices for comfort
Navigation lights have absolute priority. In case of a lack of capacity all other consumers have to be switched
off first. By a stand-by operation of the engine, even when under sail, the batteries can be brought up rather
quickly. After a while you can switch on the other consumers again.
•
Make sure that your standardized CEE plug is compatible with
the phases of the land plug socket.
•
Control and renew regularly the wear condition of the
underwater anode of the potential equalization.
