6. If the transfer switch has a test button use it to test
the complete system. The unit should start up and
the transfer switch should transfer the load to the
generator.
7. Compare the amperage reading from each leg on the
generator and ensure that none of the legs is ex-
ceeding the nameplate rating on the generator.
8. Upon completion of the test, leave all control mode
switches in the “AUTO” position.
9. The system is now ready to start and power the loads
should the power fail.
F. CONNECTING THE LOADS FOR STAND ALONE
OPERATION
WARNING -ALL WIRING MUST BE DONE IN ACCOR-
DANCE WITH NATIONAL ELECTRIC CODE NFPA 70
There are three ways the loads may be connected to
Mobile Diesel Generator.
. FRONT PANEL - A variety of receptacles have been
provided for your convenience on the front panel.
The 20 volt receptacles are powered when the volt-
age selector switch is in the 20/240 single and three
phase and 20/208 three phase volt position. The
240 volt receptacles are only usable in the 20/240
volt single and three phase position. In the 20/208
volt three phase position the 240 volt receptacles
have only 208 volts at them. See table on page 9 for
voltage outputs.
2. FULL POWER LOAD CONNECTION TERMINAL
BLOCK - For remote connections and connecting
load distribution boxes, heavy duty terminal blocks
have been provided. These terminal blocks are
located on the rear of the unit just below the Engine
Contol. The neutral and ground are connected to-
gether at this panel. For use with an isolated neutral,
remove the jumper strap between the neutral con-
nection block and the ground lug. This will isolate
the neutral from the ground and allow you single
point grounding at a distribution panel. When using
these terminal blocks be sure to use wire rated large
enough to carry your full load or the full rated load of
the generator.
3. FULL POWER CAM-LOCK CONNECTIONS - For
ease of connecting and disconnecting loads these
units have been equipped with Cam-Locks located
behind the right hand rear door. See page 8 The
same instructions for connection #2 applies. If you
need to run a isolated neutral system, the jumper
between the neutral and ground must be removed at
the terminal block.
4. GROUNDING THE UNIT - To comply with current
safety standards this generator set must be properly
grounded. Ground the Mobile Diesel Generator set
by driving an 8 ft. copper ground rod into the earth.
Then connect a #4 AWG ground cable from the
grounding lug on the generator to the ground rod.
G. UNIT STORAGE
Certain precautions must be taken if a Mobile Diesel
Generator set is to be stored for a long period of time.
The unit must be stored in a dry location to prevent the
generator winding from drawing moisture. The unit should
also be thoroughly cleaned prior to storage.
For engine storage procedures consult your local Isuzu
engine dealer. There are procedures that must be fol-
lowed in order to prevent engine damage, i.e. cylinder
rust and injector deterioration.
50 CYCLE (HZ) OPERATION
With a couple of minor changes these Mobile Diesel
Generators are capable of producing 50 Hz power. Two
changes must be made:
A. The engine must be reduced to 500 RPM governed
speed. Consult your local Isuzu Service Center for the
proper procedure for reducing the engine speed and set-
ting up the governor to operate at 500 RPM.
B. The automatic volt/hertz regulator must also be reset
to operate at 50 HZ instead of the standard 60 HZ. Refer
to the Stamford generator manual for instructions.
MAINTENANCE
The ultimate aim of a preventive maintenance program is
to maintain the equipment in optimum condition, for the
maximum amount of time during it's useful life. The de-
tection of faults before they develop into major problems
will decrease downtime. A regular schedule of cleaning
and inspection will help assure trouble-free operation.
Personnel responsible for maintenance should set up a
schedule for inspection, and cleaning at intervals calcu-
lated to keep the equipment in good condition. In making
up a schedule, keep the following in mind:
A. New equipment must be carefully monitored until
extended operation has demonstrated that it is perform-
ing satisfactorily.
B. Old equipment requires more frequent inspection
(and possibly servicing) than similar equipment that has
lower hours
C. Time spent in cleaning, inspecting and correcting
minor defects before they become major troubles saves
time in overhaul and repair.
