Electrical system

The engine is equipped with a two-pole system electrical system which means that the voltage (minus) is re-

turned directly from the starter motor minus terminal with the battery negative lead. Individual components on

the system return voltage to the starter motor minus terminal via separate cables.

WARNING! Always stop the engine and break the current using the main switches before working on the

electrical system. Isolate shore current to the engine block heater, battery charger, or accessories mounted

on the engine.

Main switch

The main switch must never be turned off before the en-

gine has stopped. If the circuit between the generator and

the battery is cut off when the engine is running the gen-

erator can be seriously damaged. For the same reason

charging circuits must never be switched over while the

engine is running.

IMPORTANT! Never break the circuit with the main

switches while the engine is running.

Fuses

12/24-volt system and drive-unit

The engine and the drive-unit are ﬁtted with automatic

circuit breakers, (1) engine and (2) drive-unit. The circuit

breakers cut the power if the system is overloaded.

If it is not possible to start the engine or if the instrument

stops working while running, the circuit breaker may have

been activated. Reset by pressing in the circuit breaker.

If the fault persists, read out the ﬂash codes and take the

necessary measures.

IMPORTANT ! Always investigate the cause of the

overload!

EVC system

The EVC system is protected through the engine circuit

breakers.

IMPORTANT ! Always investigate the cause of the

overload!
