POWER OUTPUT
WARNING: ELECTRIC SHOCK can kill;
MOVING PARTS can cause serious injury;
IMPROPER AIR FLOW AND EXPOSURE TO
ENVIRONMENT can damage internal parts.
•
Do not touch live electrical parts.
•
Stop the engine and disconnect negative (−)
battery cable from battery before making in-
ternal inspection or reconnection.
•
Ground generator as required by any applica-
ble national, state, and local electrical codes.
The generator neutral is connected to the frame;
therefore, the equipment grounding terminal
must be connected to a proper earth ground.
•
Do not connect to any electrical distribution
system normally supplied by utility power un-
less a proper transfer switch and grounding
procedure are employed.
•
Keep away from moving parts such as fans,
belts, and rotors.
•
Keep all covers and panels in place while op-
erating.
Warranty is void if unit is operated with any por-
tion of the outer enclosure removed.
ELECTRIC SPARKS can cause fire.
•
Disconnect weld cables when using auxiliary
power.
The weld output terminals are electrically ener-
gized when the engine is running and the con-
tactor (if applicable) is energized.
•
Watch for fire.
•
Have a fire extinguisher nearby, and know
how to use it.
LOW VOLTAGE AND FREQUENCY can dam-
age electrical equipment.
•
Turn off or unplug all electrical equipment
connected to auxiliary power before starting
or stopping the engine.
When starting or stopping, the engine has low
speed which causes low voltage and frequency.
5-1. GENERAL
Calculate load requirements before connecting equip-
ment to the auxiliary power terminals on terminal strip
3T. For best performance (voltage and frequency regu-
lation), limit connected load to approximately 90% of
generator capability.
A brief period (less than 5 seconds) of large current draw
is required for starting motor-driven equipment. This
generator can supply 25% of rated current output at the
terminal strip for motor starting. Disconnect motor from
generator before starting engine. Use adequate size
cords so that voltage drop at the motor is not excessive.
Voltage drops significantly when starting motor-driven
equipment.
Ground fault circuit interrupters (GFCI) may be re-
quired. Check local and state codes, and the latest issue
of the National Electrical Code.

Figure 4-2)
WARNING: ELECTRIC SHOCK can kill.
•
Do not touch live electrical parts.
•
Stop engine, and disconnect negative (−)
battery cable from battery before beginning
this installation.
MOVING PARTS can cause serious injury.
•
Keep away from moving parts such as fans,
belts, and rotors.
HOT SURFACES can cause severe burns.
•
Wear protective gloves and clothing when
working near a hot engine.
•
Allow components to cool completely be-
fore touching.
IMPORTANT: All directions, such as left or right, are
with respect to the operator facing the welding generator
front panel. Retain all hardware removed during this
procedure for reinstallation unless specifically told
otherwise.
