NOTE 1: The frame ground wire must be moved when changing from 110 volts 50 hertz to
110/220 volts 50 hertz. For making connections to the AC terminal block, use terminal ends
for #10 studs that will accept #6 multi-strand wire when the generator is wired for 120 volts,
or use #8 when the generator is wired for 120/240 volts. Use an approved cable clamp to
protect and secure the wire from chafing where it exits the generator housing.
NOTE 2: The neutral and frame ground (-), which are normally combined, can be separated
for those systems requiring a separate neutral from common ground. The generator's frame
must
be connected to the vessel's common ground for safety reasons.
Generator Frequency
1. Frequency is a direct result of engine/generator speed: 1800 rpm
=
60 hertz; 1500 rpm
=
50 hertz.
2. To change generator frequency follow the steps below.
A.
Connect the AC output leads to the AC terminal block, following the illustrations on the preceding page.
B. Adjust the engine's speed to obtain the frequency corresponding to the voltage selected.
C. Adjust the no-load voltage if it is needed by the compound transformer.
D. Load the generator to the new amperage rating and reposition the loaded voltage tap to position X, V,
or Z as needed to maintain acceptable voltage output at full rated amperage output.
NOTE: Volts x Amperage
=
Kilowatts
Engine speed is increased or decreased by adjusting the length of the linkage between the throttle arm and
solenoid plunger with the plunger completely bottomed in the solenoid.
