SAFETY PRECAUTIONS

WARNING
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.
------------------------------------------------------------------------

INPUT CABLE

The standard input cable between the LN-23P and the
power source consists of a control cable and an elec-
trode cable. With the power source turned off,
install the input cable per the following instructions:
• Connect the end of the control cable into the mating
14-pin receptacle on the power source. Connect
the electrode cable to the negative output stud on
the power source.
• Connect the input control cable polarized plug into
the mating 8-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.
INSTALLATION
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 out of the 8-pin
receptacle on the control cable. 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.
