the voltage in your area compare your incoming power or
load name plates to the voltage table below.
1. 120/240 Three Phase* (Delta/Series configuration) -
This configuration will produce the following line-to-line
and line-to-neutral voltage. In this selector switch posi-
tion, all of the receptacles on the front panel are pow-
ered.
L1 - L2 - L3 240 Volts three phase
L1 - L2 240 volts single phase
L2 - L3 240 volts single phase
L1 - L3 240 volts single phase
L1 - N 120 Volts
L2 - N 120 Volts
L3 - N 208 volts
*This selector position is also used for single phase
120/240 output, using only the L1 and L2 leads. The
L3 three phase output lead is the “wild” leg in the delta
configuration and is used only for three phase loads.
2. 120/208 Three Phase (Low/Parallel WYE configura-
tion) This configuration will produce the following line-to-
line and line-to-neutral voltage. Use of this selector
switch position allows utilization of the 120 volt receptacle
only. The 240 volt receptacles cannot be used as the
voltage at them will be 208 volts, the line to line voltage.
L1 - L2 - L3 208 Volts three phase
L1 - L2 208 volts single phase
L2 - L3 208 volts single phase
L1 - L3 208 volts single phase
L1 - N 120 Volts
L2 - N 120 Volts
L3 - N 120 volts
3. 277/480 Three Phase (High/Series WYE configura-
tion) This configuration will produce the following line-to-
line and line-to-neutral outputs. The 120 volt receptacles
are the only panel receptacles powered in this voltage
configuration. They are limited to 12 Amps total.
L1 - L2 - L3 480 Volts three phase
L1 - L2 480 volts single phase
L2 - L3 480 volts single phase
L1 - L3 480 volts single phase
L1 - N 277 Volts
L2 - N 277 Volts
L3 - N 277 volts
After you have selected the correct voltage for your
application and locked the selector switch, do the same
with the main line circuit breakers. Be sure to secure the
lock bar in place. This will prevent the incorrect breaker
from being turned on.
B. STARTUP CHECKLIST
Before initial start up and each subsequent start complete
the following checklist:
1. Check oil level, refill with proper grade oil.
2. Check coolant level, refill with proper mixture of
coolant. See engine manual.
3. Check for loose bolts or hardware.
4. Check tire pressure. (35 psi)
5. Trailer level to within 15 degrees.
6. Battery securely fastened, connection clean and
tight, and proper fluid level.
7. Fuel tank filled with the proper grade of diesel
fuel.
8. Check the fan belt for tightness and excessive
wear.
9. Check hoses and clamps for leakage.
10. Check the air cleaner indicator. Service only
when indicated. Do not over-service.
11. Clean out dust cup on the air cleaner.
C. STARTING
CAUTION: EQUIPMENT DAMAGE
DO NOT ATTEMPT TO JUMP/BOOST START THIS
UNIT. TURN THE DC BREAKER “OFF” AND RE-
CHARGE THE BATTERY WITH A BATTERY
CHARGER.
1. Select the desired voltage on the voltage selector
switch and lock in place.
2. Turn off both main line circuit breakers.
3. Rotate the start switch to the “run” position. In this
position without the engine running the safety latching
relay will pop out.
4. While depressing the safety latching relay, rotate the
start switch to the start position. This will engage the
starter and the fuel solenoid allowing the engine to
start.
5. As the engine starts release the start switch but keep
the safety latching relay depressed. This will allow
the spring loaded start switch to return to the run
position.
6. After the engine has built up at least 15 psi of oil
pressure, you can release the safety latching relay. If
you release the safety latching relay before the
engine has built oil pressure, the button will pop out,
shutting the engine back down.
7. After the engine is running at proper speed, adjust the
voltage to the desired level using the external voltage
rheostat.
8. Turn on the proper main line breaker (either high or
low voltage) and padlock the lock bar to prevent the
incorrect breaker from being turned on.
9. To stop the unit simply turn the start switch to the off
position. This will disconnect the 12 Volt DC to the
fuel solenoid shutting the unit down.
