AUXILIARY POWER WHILE WELDING

Simultaneous welding and power loads are permitted
by following Table I. The permissible currents shown
assume that current is being drawn from either the
120V or 240V supply (not both at the same time). Also,
the "Output Control" is set at "10" for maximum auxil-
iary power.

STANDBY POWER CONNECTIONS

The RANGER® 10,000 or RANGER® 10,000 PLUS is
suitable for temporary, standby, or emergency power
using the engine manufacturerʼs recommended mainte-
nance schedule.
The RANGER® 10,000 or RANGER® 10,000 PLUS
can be permanently installed as a standby power unit
for 240V-3 wire, single phase 38 ampere service.
WARNING
Connections must be made by a licensed electri-
cian who can determine how the 120/240V power
can be adapted to the particular installation and
comply with all applicable electrical codes. The fol-
lowing information can be used as a guide by the
electrician for most applications. (Refer to the con-
nection diagram shown in Figure A.1.)

RANGER® 10,000 & RANGER® 10,000 PLUS
1. Install a double pole, double throw switch between
the power company meter and the premises
disconnect.
Switch rating must be the same or greater than
the customerʼs premises disconnect and service
overcurrent protection.
2. Take necessary steps to assure load is limited to
the capacity of the RANGER® 10,000 by installing
a 40 Amp 240V double pole circuit breaker.
Maximum rated load for the 240V auxiliary is 38
amperes. Loading above 38 amperes will reduce
output voltage below the allowable -10% of rated
voltage which may damage appliances or other
motor-driven equipment.
3. Install a 50 amp 120/240V plug (NEMA type 14-50)
to the Double Pole Circuit Breaker using a 4 con
ductor cable that is properly sized for the ampacity
and length to be used.
(The 50amp 120/240V plug is available in the
optional plug kit.)
4. Plug this cable into the 50 amp 120/240V
receptacle on the RANGER® 10,000 case front.
