COLISEUM GENERATOR
AC VOLTAGE CONNECTIONS
The frnme ground wire (green) must be properly positioned
when changing the AC output configuration of the AC
terminal block. For making connections to the AC breaker,
use terminal ends for 114 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
1. Frequency is a direct result of engine/generator speed:
1800
rpm
= 60 hertz; 1500 rpm = 50 hertz.
2. 1b change generator frequency, follow the steps below:
Connect the AC leads to the AC breaker and isolation
posts as the illustrations show for the hertzlvoltage
desired. Ensure that the case ground wire is connected
to the correct isolation post neutral ground stud.
3. Remove or install the jumper on the automatic regulator
(depending on the frequency).
NOTE:
The
green growui wire
may
be removed in those
instal1ations where the AC circuit hos a separate neutral
and
growui circuit.
This
will prevent the unit from being a
growui source in the vesseL
4. Open the AC circuit breaker.
S. Start the generator and adjust the engine speed to the
correct
no-load hertz, then adjust the voltage rheostat on
the regulator to the corresponding AC output.
