CONTROL CABLE
N.B.
CONNECT THE LN-8 CONTROL CABLE GROUND LEAD TO THE FRAME TERMINAL MARKED NEAR THE POWER SOURCE TERMINAL STRIP
OR TO AN UNPAINTED FRAME SCREW. THE POWER SOURCE MUST BE PROPERLY GROUNDED.
N.A. EXTEND LEAD #21 USING #14 OR LARGER INSULATED WIRE PHYSICALLY SUITABLE FOR THE INSTALLATION. AN S16586-[ ]
REMOTE VOLTAGE SENSING WORK LEAD IS AVAILABLE FOR THIS PURPOSE. CONNECT IT DIRECTLY TO THE WORK PIECE, KEEPING IT
ELECTRICALLY SEPARATE FROM THE WELDING WORK LEAD CIRCUIT AND CONNECTION. FOR CONVENIENCE, THIS EXTENDED LEAD #21
SHOULD BE TAPED TO THE WELDING WORK LEAD. (THIS EXTENDED #21 LEAD CONNECTION REPLACES THE NEED TO EMPLOY THE
REMOTE WORK LEAD ACCESSORY ON LN-8 METER KITS WHICH HAVE A DIRECT WORK LEAD JACK).
N.B. IF USING AN OLDER LN-8 CONTROL CABLE (PRIOR TO USE OF A, B, AND C MARKING): CONNECT LEAD #76 TO #76 ON TERMINAL
STRIP, CONNECT LEAD #77 TO #75 ON THE TERMINAL STRIP, AND TAPE UP LEAD #75.
