Generator Frequency
~ ~ 1~- -["requencyts-a-rtirecrresult-of-enginelgeneratonpeed:~-
1800 'fpm = 60 hertz
1500 nnp = 50 hertz
2. To change generator frequency, follow the steps below:
a. Reconfigure the AC output connections on the
twelve stud terminal block following the illustrations
below. Install the correctly rated AC breaker for the
Hertz selected.
c, Shut off the 20 amp DC panel breaker and move the

the hertz sglected - ON for 50 hertz, OFF for 60
. ·.hertz, Then tum the DC'breaker back on.
d. Shut off the AC breaker "and start the unit. Monitor
. the no-load AC voltage.
If
a voltage adjystment is
needed, add or remove shim material from under the
laminated steel bar of the compound transfonner.
60 hertz No-Load Voltage 121-124 volts
50 hertz No-Load Voltage 232-235 volts
e. :Close the AC breaker and load the generator and
monitor operation.
b. Properly connect the leads from the voll'!ge sensing
