The electrical equipment of the engine comprises a series ofcomponents provided separately from the engine to enablean easy and diversified installation, according to the Yard'sdesign choices. The need to make accessible, at sea orunderway, the controls to the electrical components and to

the connector for diagnostics contained in the relay box maybe met through different installation arrangements.

Together with the coupling of all the wiring connectorsnecessary to carry out the connection wiring (3) for water in fuel sensor (4), the power network and connection of the accumulator with the engine wiringorder to complete the installation In order to activate function which stops the engine in case of excitation, necessary to connect the JECCM andJECCFconnectors weach other.
