Installation Instructions
The generator is equipped with a PEN protective conductor system as standard (this means that the neutral conductor
is also used as protective conductor).
If a separate protective conductor is necessary (i. e. according to national safety regulations), the bridge circuit at the
generator and the AC-Control box between null and generator housing has to be removed. Afterwards a separate
protective conductor has to be installed and connected to all the system’s attached metallic housings.
It is recommended to provide a voltage indication (voltmeter) and also a power indication, if applicable, in the installation
system. The voltmeter (and power indication, if applicable) has to be installed behind the selector switch so
that the voltage for every possible voltage source may be indicated. A separate voltmeter for the generator itself, is
therefore not required.
5.12.5.2 Electrical fuse
It is absolutely essential that the electrical system installation is inspected by a qualified electrical technician. The
generator should have its own AC input electrical fuse. This fuse should be sized so that the rated current of the generator
on each of the individual phases is not exceeded by more than 25%.
Data for gensets with power output greater than 30 kW on request!
The fuses must be of the slow type. A 3-way motor protection switch must be installed to protect the electrical motor.
Required fuse see Tabelle 9.6-1, “Nennströme,” auf Seite 219
5.12.5.3 Required cable crosssections
The following recommended electrical cable dimensions (cross sections) are the minimum required sizes for a safe
installation. (see “Cable cross section” on page 208.)
5.12.5.4 Disconnector - power source selector (three way cam switch)
A power source selector switch must be installed between the generator (or if applicable, AC-Control box)
and the ship's electrical supply system. This switch must ensure that all AC consumers can be switched off
at once. This switch should also be installed to keep the generator and shore (grid) power systems sepa-
