  2. Start battery port engine

  3. Combine batteries switch

  4. Service batteries

  5. Bow thruster battery

  6. Direct fuses: direct supply fuses/power switches

  7. Regular fuses

The main switch panel is located on the port side wall in the cockpit, aft of the galley (see diagram in section 4.2 Electrical system).

If you have selected optional accessories requiring a high level of power,  the heavy-duty fuses for them are located in the technical space.

Main switches

The 12 V equipment is controlled by the main switches on the main switch panel and the individual function buttons on the steering console.

  • The start main switch controls the engine functions in the steering console.

  • The combi main switch is used to combine the power of the service batteries and the start batteries, in case the start batteries do not have enough power to start the engines.

  • The bow thruster main switch controls the bow thruster and optional anchor windlass.

  • The service main switch controls all other devices.

Direct supply fuses/switches

Risk of material damage.

Devices connected to direct supply fuses can become overheated and damaged if the direct supply switches are turned off too soon.

Always keep the direct supply switches turned on, even when switching power off from the device or appliance.

The Direct fuses buttons work both as fuses and power switches for devices that need current even when the main switches are turned off. The following appliances and devices are connected to them:

  • Bilge pump

  • Fridge

  • Second fridge*

  • Heater*

  • Audio channel memory*

  • Aux for water tank or retrofits*

* Optional

When a direct supply fuse's power switch is pushed down, the switch is on. When pushed up, it is off.

Regular fuses

The regular fuses are connected to the devices that are powered by the service main switch, but fuses are also located in other areas. Positions F16-F35 are spare fuses for retrofits. 

Heavy-duty fuses

For components that require high level of power, there are heavy-duty fuses. There heavy-duty fuses are located in three difrerent locations.

Located at the front of the technical space there are two black main switch modules. The one further aft is connected to the start batteries. The start battery module is remotely controlled with the start switches on the main switch panel.

The other module in the technical space is for optional equipment requiring a high level of power.

There is an additional heavy-duty fuse panel located under front cabin bed. This panel is connected to the bow thruster and the optional front anchor windlass. The fuses for the bow thruster and anchor windlass are provided by the manufacturer.
