4.4 Electrical Connections
In order connect the unit to the boat's electrical system, proceed as follows:
- Before turning on the appliance, check to make sure that the voltage of the
electrical system and/or battery complies with that which is indicated on the unit's
data plate.
- Always use cables with sufficient section (see recommendations in the following
table).
- Always use normal or tinned multi-conductor copper wire, suitable for marine
environments.
- Connect the refrigerator directly to the battery or to the relative main switch and
make sure that the system is equipped with an electric device that's capable of
protecting the circuit against possible overcurrents.
If the power supply voltage is different from 12/24Vdc, install a ΔI 0.03A differential
circuit breaker. Avoid connecting the unit via the boat's control panel as this could
result in voltage drops.
- Insert a fuse upstream from the refrigerator (see the table below).
- Connect the red wire to the electrical system's positive terminal, and connect the
black wire the negative terminal. Use a pressed lug terminal that's suitable for the
cable's size.
- A separate switch that simultaneously disconnects the power cables must be
installed upstream from the refrigerator. Check to make sure that the installed switch
supports the corresponding load indicated in the table below:
