AUXILIARY POWER

CAUTION
Do not connect any plugs that connect to the
power receptacles in parallel.
------------------------------------------------------------------------
Start the engine and set the "IDLER" control switch to
the "High Idle" mode. Set the "CONTROL" to 10.
Voltage is now correct at the receptacles for auxiliary
power. This must be done before a tripped GFCI
receptacle can be reset properly. See the MAINTE-
NANCE section for more detailed information on test-
ing and resetting the GFCI receptacle.
The RANGER® 3 PHASE can provide both three
phase and single phase power, up to 11,500 watts of
480 volts AC, three phase 60Hz power for peak use,
and up to 10,500 watts of 480 volts AC, three phase
60Hz power for continuous use, up to 10,500 watts of
120/240 volts AC, single phase 60Hz power for peak
use, and up to 9,500 watts of 120/240 volt AC, single
phase 60Hz power for continuous use. The front of the
machine includes four receptacles for connecting the
AC power plugs; one 20 amp 480 volt 3 phase NEMA
receptacle, one 50 amp 120/240 volt NEMA 14-50R
receptacle and two 20 amp 120 volt NEMA 5-20R
receptacles. Output voltage is within +/-10% at all
loads up to rated capacity. Do not use 3 phase power
and single phase power simultaneously. All auxiliary
power is protected by cuircuit breakers.
120/240 VOLT DUAL VOLTAGE RECEPTACLE
The 120/240 volt receptacle can supply up to 40 amps
of 240 volt power to a two wire circuit, up to 40 amps
of 120 volts power from each side of a three wire cir-
cuit (up to 80 amps total). Do not connect the 120 volt
circuits in parallel. Current sensing for the automatic
idle feature is only in one leg of the three wire circuit as
shown in Figure A.1.

120 V GFCI DUPLEX RECEPTACLES
A GFCI (Ground Fault Circuit Interrupter) electrical
receptacle is a device to protect against electric shock
should a piece of defective equipment connected to it
develop a ground fault. If this situation should occur,
the GFCI will trip, removing voltage from the output of
the receptacle. If a GFCI receptacle is tripped see the
MAINTENANCE section for detailed information on
testing and resetting it. A GFCI receptacle should be
properly tested at least once every month.
The 120V auxiliary power receptacles should only be
used with three wire grounded type plugs or approved
double insulated tools with two wire plugs.
The current rating of any plug used with the system
must be at least equal to the current load through the
associated receptacle.
480 VOLT 3 PHASE RECEPTACLE WITH GROUND
The 480 volt receptacle can supply 12.6 amps of 3
phase power, or up to 15 amps of single phase power.
A NEMA L16-20P plug is required to use this recepta-
cle. The ground (GND) connection is connected to the
machine frame, it is NOT the neutral of the three phase
connection, and should under no circumstances be
connected to the neutral of any 3 phase load. Do not
connect 480V 3 phase to single phase premises
wiring.
If 480 volt single phase load is to be run, the X lead
must be one of the leads in the circuit in order for the
automatic idle to function. Using a NEMA plug L16-
20P, connect either X and Y or X and Z to the recepta-
cle, as well as the machine ground. See Figure A.2.
NOTE: Use of 3-Phase AC power is not recommend-
ed while welding.
