N.A. USE POWER SOURCE POLARITY SWITCH TO SET FOR DESIRED ELECTRODE POLARITY. POSITION THE OUTPUT SELECTOR SWITCH ON THE POWER SOURCE TO THE CV POSITION.

N.B. 3 CONDUCTOR #16 POWER CORD PHYSICALLY SUITABLE FOR THE INSTALLATION AND PLUG RATED AT 115 VOLTS 15 AMPERES AC.

N.C. PLUG INTO 115 VOLT AC RECEPTACLE ON WELDER CONTROL PANEL OR OTHER 115 VOLT AC SUPPLY RATED AT A MINIMUM OF 500 VOLT AMPERES.

N.D. LEADS #21 AND GND. DO NOT APPEAR ON LN-7’S WITH CODES BELOW 7026.

N.E. WELDING CABLES MUST BE OF PROPER CAPACITY FOR THE CURRENT AND DUTY CYCLE OF IMMEDIATE AND FUTURE APPLICATIONS. (SEE OPERATOR’S MANUAL.)

N.F. IF LN-7 IS EQUIPPED WITH A METER KIT, EXTEND LEAD #21 USING #14 OR LARGER INSULATED WIRE PHYSICALLY SUITABLE FOR THE INSTALLATION. AN S16586-"LENGTH" REMOTE VOLTAGE SENSING WORK LEAD MAY BE ORDERED FOR THIS PURPOSE. CONNECT IT DIRECTLY TO THE WORK PIECE INDEPENDENT OF THE WELDING WORK CABLE. FOR CONVENIENCE, THIS EXTENDED #21 LEAD SHOULD BE TAPED TO THE WELDING WORK LEAD.

N.G. TAPE UP BOLTED CONNECTION WHERE LEAD #21 IS EXTENDED.

N.H. IDLER SWITCH ON POWER SOURCE MUST BE IN HIGH IDLE POSITION.

N.J. IF AN OPTIONAL K857 REMOTE OUTPUT CONTROL IS USED, CONNECT IT TO THE RANGER 300 D AMPHENOL CONNECTOR.

NOTE: PLACE OUTPUT CONTROL SWITCH IN "OUTPUT CONTROL REMOTE" POSITION WHEN REMOTE OUTPUT CONTROL IS USED.

CAUTION: ANY SPEED UP OF THE ENGINE RPM BY CHANGING THE GOVERNOR SETTING OR OVERRIDING THE THROTTLE LINKAGE WILL CAUSE AN INCREASE IN THE AC AUXILIARY VOLTAGE. IF THIS VOLTAGE GOES ABOVE 140 VOLTS, THE LN-7 CONTROL CIRCUIT WILL BE DAMAGED. THE ENGINE GOVERNOR SETTING IS PRE-SET AT THE FACTORY - DO NOT ADJUST ABOVE RPM SPECIFICATIONS LISTED IN ENGINE WELDER OPERATING MANUAL.
