CONNECTION OF RANGER 8+ DIESEL TO LN-7 & K240 CONTACTOR KIT
WARNING: Turn the power off when making connections.
N.A. Use power source polarity switch to set for desired electrode
polarity. Position the output selector switch on the power
source to the CV position.
N.B. 3 conductor #16 power cord physically suitable for the instal-
lation and plug rated at 115 volts 15 amperes AC.
N.C. Plug into 115 volt AC receptacle on welder control panel or
other 115 volt AC supply rated at a minimum of 500 volt-
amperes.
N.D. Leads #21 and GND. do not appear on LN-7’s with codes
below 7026.
N.E. Welding cables must be of proper capacity for the current
and duty cycle of immediate and future applications.
N.F. If LN-7 is equipped with a meter kit, extend lead #21 using
#14 or larger insulated wire physically suitable for the installa-
tion. An S16586-”length” remote voltage sensing work lead

may be ordered for this purpose. Connect it directly to the
work piece independent of the welding work cable. For conve-
nience, this extended #21 lead should be taped to the welding
work lead.
N.G. Tape up bolted connection where lead #21 is extended.
N.H. Idler switch on power source must be in high idle position.
N.J. If an optional remote output control is used, connect it to this
terminal strip or 6 pin Amphenol receptacle. NOTE: Terminal
strip or 6 pin Amphenol receptacle not available on all power
sources.
CAUTION: Any speed up of the engine RPM by changing the gov-
ernor setting or over-riding the throttle linkage will cause an
increase in the AC auxiliary voltage. If this voltage goes
above 140 volts, the LN-7 control circuit will be damaged. The
engine governor setting is pre-set at the factory - do not
adjust above RPM specifications listed in engine welder oper-
ating manual.
