5.1 Electrical system

The electrical system of your boat consists of a state-of-the-art power package which covers your power needs onshore and offshore.

Risk of electric shock, fire or explosion.

Remember that water and electricity are a bad combination.

Let only a competent marine electrical technician carry out any installation, alteration or maintenance work to the electrical system.

Risk of death, electric shock or injury.

Working on the electrical installation while the system is energized can cause an electric shock.

Never work on the electrical installation while the system is energized.

Risk of electric shock or damage to the equipment.

Never alter or modify the rated current amperage of overcurrent protective devices.

The power package is a combination of batteries, shore power and the components of the generator replacement system. The NMEA network connects the different components of your power package. You can monitor the operation of the power package with the CZone application on the chartplotter.

The less you use the electrical equipment on your boat, the longer the system can give you power.

  • Main switches and indicators
    The fuse panel contains main switches and indicators for the equipment on your boat. Heavy-duty fuse panels and air conditioning fuse panel are located at the aft of the boat.
  • Fuses
    The fuse panel on your boat contains separate fuses for the 12 V battery power and for the 110 V or 230 V shore power. A heavy-duty fuse panels and the air-conditioning fuse panel at the aft of the boat contain ANL fuses and air-conditioning fuse.
  • Batteries
    The batteries give your boat 12 V DC power when used offshore.
  • Shore power
    When onshore, you can run your boat’s equipment and charge the batteries with the 110 V or 230 V alternative current (AC) shore power.
  • Generator replacement system
    The optional generator replacement system gives you extended use of 110 V or 230 V power to run the electrical appliances and equipment on your boat when you have no access to shore power.
