GENERATOR AC VOLTAGE CONNECTIONS
AC VOLTAGE CONNECTIONS
The frame ground wire (green) must be properly positioned
when changing the AC output configuration of the AC
terminal block. For making connections to the AC terminal
block, use terminal ends for l/4 inch studs that will accept
multi strand copper wire sized for the amperage rating from
the hot lead connection. The frame ground green wire
connects between the neutral stud and the generator frame.
Generator Frequency
I. Frequency is a direct result of engine/generator speed:
1800 rpm = 60 hertz; 1500 rmp = 50 hertz.
2. To change generator frequency, follow the steps below:
120/240V 60Hz
230V 50Hz

120V 60Hz
NOTE: When changing from 60 Hz
to 60 Hz see operator·. manual.
Configure the AC terminal block for the desired voltage
frequency as shown. Ensure that the case ground wire is
connected to the correct terminal block neutral ground
stud.

regulator.
3. Remove or install the jumper on the automatic regulator
(depending on frequency). Refer to BE GENERATOR.
NOTE:
The green ground wire may be removed in those
installations where the AC circuit has a separate neutral
and ground circuit. This will prevent the unit from being
a ground source in the vessel.
