*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 recep-
tacle 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. None of the front
panel receptacles are powered in this voltage configura-
tion.
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 com-
plete the following checklist:
1. Check oil level, refill with proper grade oil.
2. Check coolant level, refill with 50/50 mix of deminer-
alized water and a permanent ethylene-glycol antifreeze.
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. ELECTRIC STARTING
(Normal portable use)
CAUTION: EQUIPMENT DAMAGE
DO NOT ATTEMPT TO JUMP/BOOST START THIS
UNIT. TO DO SO MAY DAMAGE THE ELECTRONIC
MICROPROCESSOR IN THE ENGINE CONTROL.
TURN THE DC BREAKER “OFF” AND RECHARGE
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. Turn the control switch to the “run” position. In this
position the unit will go into an automatic start routine.
First the glow plugs will come on and 12 seconds later
the starter will engage. The starter will automatically
disengage as the engine comes up to proper operating
speed.
8. After the engine is running at proper speed, adjust
the voltage to the desired level using the external voltage
rheostat.
9. 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.
D. REMOTE STARTING AND
CONNECTION
(Standby applications)
1. Complete the manual starting procedure above to
insure the system is set up properly.
2. Insure the start switch is in the “off” position during
installation of the remote start connections.
3. Locate the remote start terminal block. This termi-
nal block is located next to the full power connections,
behind the access door at the bottom of the control panel.
4. Locate the remote start terminals in your remote
automatic transfer switch (ATS). The ATS terminal
block and wire numbers will vary with each ATS
manufacturer. The MD25 requires a contact closure for
start.
WARNING: EQUIPMENT DAMAGE
THE REMOTE “SIGNAL” MUST BE A “DRY” (NON-
POWERED) CONTACT CLOSURE. USING A POWER
CONTACT WILL CAUSE PERMANENT DAMAGE TO
