1.2 Main panel fuses / shore power
supply
If turned on, the LEDs next to the switch are shining
and indicate that the circuit is powered with 12 / 220
Volts.
-
The small green LED for shore power always
needs to be checked when connected to the
jetty. If you are plugged in shore power and
the LED is not shining, the batteries are NOT
being charged and you have to check the
main fuse.
-
Water heater is only working when connected
to the shore power. If not used you always
have to turn off the heater to prevent
damage to the electronics.
-
All boats are equipped with a power inverter
which is usually located behind the panel or
under the chart table. If used the inverter
draws electricity from the service batteries
even if there is no electronic devices
connected. If not needed the inverter has to
be switched off in order to prevent service
batteries from getting empty.
-
Voltage indicator: always make sure the
voltage does not drop below 12V
Attention! If devices are not being used always turn
off the panel switch too!
(e.g. running the bilge pump continuously, the pump
mechanism runs hot and breaks down)
1.1 Panel
While doing the check in we will
give you the basic explanations
(main important functions) of the
instruments. Panel switches are
clearly labeled.
