1. Turn off engine and/or disconnect all electrical power before performing this installation.
2. HARDWARE: (LHC only)
• Disconnect the WIPER and RESISTOR wires from the M5090C rheostat in the welding machine.
• Connect the WIPER wire to the BLACK wire from the LHC remote and insulate the connection.
• Connect the RESISTOR wire to the WHITE wire from the LHC remote and insulate the connection.
• Connect the GREEN wire from the LHC remote to frame ground.
3. TWISTLOCK PLUG: (LHC only - must have field remote facilities installed.)
• Make connection by aligning plug to mating receptacle on power source, inserting plug into the receptacle and turning clockwise
as far as it will go.
4. TERMINAL STRIP: (LHC-775)
• Make connection by attaching the appropriate numbered wire to it’s mating terminal on the power source.
5. AMPHENOL PLUG: (LHC-857)
• Make connection by aligning keyway to mating receptacle on power source, inserting plug and tighten by threading collar
clockwise onto receptacle.
6. If the power source has a Contactor Switch - place it into the STANDARD or PANEL position.
7. If the power source has a Current or Voltage control switch - place it in the REMOTE position.
