The cam-type switch must have 2 poles, so that "MP" and "phase" can be switched off.
If a 3-phase current system is also installed with the option of supplying from either the generator
or shore power, an additional switch must be installed to keep these systems separate.
An alternative to a manual rotating switch is an automatic power relay. When the generator is not
running, the relay remains in the shore power position. As soon as the generator is running, the
power relay switches automatically to the generator position.
Note: If the system has both single and 3-phase AC, it is CRITICAL that the two systems
remain SEPARATE!
Protection conductor
The generator is provided with a PEN safety system, as standard, which connects the 3-phase
delta centre point "N" to the safety ground strap.
If a separate ground protection cable is necessary (i.e. due to national safety regulations), the
bridge between the generator housing and ground (in the AC-Control box) must be disconnected.
Once such a ground protection cable is installed, it must be connected to the ground straps of all
on board electrical devices.
In order to monitor the electrical system, it is recommended to install a voltmeter (and, if possible,
a current meter) down line from the power source selector switch so that all respective power
sources can be monitored. A separate voltmeter for the generator, itself, is therefore not required.
Electrical fuses
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 fuses. The fuses should be
sized such that the rated current of the generator on each of the individual phases is not excee-
ded 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 fuses see Tabelle 8, “Rated current,” auf Seite 112
Required cable cross-sections
The following recommended electrical cable dimensions (cross sections) are the minimum requi-
red sizes for a safe installation. (siehe Tabelle 9, “Cable cross-section,” auf Seite 112)
