LN™-23P
INPUT CABLE
The standard 25 foot input cable between the LN™-
23P and the power source with Adapter Kit consists of
a six-conductor control cable and a 1/0 electrode
cable. The control cable has lugged leads on the
power source end and a polarized plug on the wire
feeder end. With the power source turned off,
install the input cable per the following instructions:
• Connect the end of the control cable with the
lugged leads to the LN™-23P Adapter Kit. Connect
the electrode cable to the negative output stud on
the power source.
NOTE: If two LN™-23P’s are connected to an
Adapter Kit, connect the feeder that will be used at
the lowest voltage setting to Feeder “A” terminal
strip. If one LN™-23P is used, connect it to Feeder
“A” terminal strip.
• Connect the input control cable polarized plug into
the mating 6 pin receptacle on the rear of the con-
trol section of the LN™-23P. Tighten the threaded
locking collar until the connector is completely
seated.
• Unclip the rubber retaining strap that holds the wire
enclosure cover in place and remove the cover.
Push the wire drive section door latch towards the
rear of the LN™-23P and open the door. Route the
electrode cable through the large rubber grommet
in the rear of the wire feed section and connect the
lug to the brass conductor block at the front of
motor-gearbox assembly using the bolt provided.
Attach the control cable strain relief hook to bracket
on the frame of the LN™-23P.
SAFETY PRECAUTIONS
ELECTRIC SHOCK can kill.
• Only qualified personnel should
perform this installation, maintenance
and troubleshooting work.
• Turn off the input power at the fuse box before
working on other equipment connected to the
welding system at the disconnect switch or fuse
box before working on this equipment.
• Do not touch electrically hot parts.

WARNING
WORK CABLE AND REMOTE VOLTAGE
SENSING WORK LEAD
• Connect a work cable of sufficient size and length,
per the following table, between the proper output
stud on the power source and the work. Be sure
the connection to the work makes tight metal to
metal contact.
Above cable sizes are based on a maximum voltage drop of
4.3 volts in the combined lengths of electrode and work
cable at 350 amps.
•
Connect a 12 AWG or larger rubber covered flexi-
ble lead physically suitable for the installation to the
voltage sensing work lead coming the Adapter Kit.
For convenience, wrap the voltage sensing lead
around the work lead and tape in place. Connect
directly to the work or to the work cable connection
on the work piece. This lead supplies the voltage to
the voltmeter in the LN™-23P and also supplies
the power to the LN™-23P drive motor.
