N.A. ON EARLIER DC-600'S, #67 TERMINAL WAS ALSO ON THE TERMINAL STRIP.
N.B. WELDING CABLES MUST BE OF PROPER CAPACITY FOR THE CURRENT AND DUTY CYCLE OF IMMEDIATE AND FUTURE APPLICATIONS.
N.C. EXTEND LEAD #21 USING #14 OR LARGER INSULATED WIRE PHYSICALLY SUITABLE FOR THE INSTALLATION. AN S-16586 - [ ] REMOTE VOLTAGE SENSING WORK
LEAD IS AVAILABLE FOR THIS PURPOSE. CONNECT IT DIRECTLY TO THE WORK PIECE KEEPING IT SEPARATE FROM THE WELDING WORK CABLE CONNECTION
TO THE WORK PIECE. FOR CONVENIENCE, THIS EXTENDED #21 LEAD SHOULD BE TAPED ALONG THE WELDING WORK CABLE.
N.D. TAPE UP BOLTED CONNECTION.
N.E. CONNECT THE NA-5 CONTROL CABLE GROUNDING LEAD TO THE FRAME TERMINAL MARKED NEAR THE POWER SOURCE TERMINAL STRIP. THE POWER
SOURCE MUST BE PROPERLY GROUNDED.
N.F. IF USING AN OLDER K-215 CONTROL CABLE: CONNECT LEAD #75 TO #75 ON TERMINAL STRIP, CONNECT LEAD #76 TO #76 ON TERMINAL STRIP, CONNECT
LEAD #77 TO #77 ON TERMINAL STRIP.
N.G. THE JUMPERS ON THE NA-5 VOLTAGE BOARD MUST BE CONNECTED AS FOLLOWS: CONNECT RED JUMPER TO PIN "S". CONNECT WHITE JUMPER TO PIN "B".
N.H. CONNECT A JUMPER FROM "N" TO "P". THERE IS NO NPS TERMINAL STRIP ON DC-600 CODES ABOVE 8200.
N.J. FOR PROPER NA-5 OPERATION, THE ELECTRODE CABLES MUST BE SNUGGED UNDER THE CLAMP BAR ON THE LEFT SIDE OF THE NA-5 CONTROL BOX.
