N.A. Welding cables must be of proper capacity for the current and duty cycle of immediate and future applications.

N.B. Extend lead 21 using #14 or larger insulated wire physically suit- able 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 #21 lead 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-7 meter kits which have a direct work lead jack. An LN-7 not equipped with a meter kit does not require lead 21 to be extended.)

N.C. Tape up bolted connection.

N.D. Connect the control cable ground lead to the frame terminal

marked near the power source terminal strip. The power source must be properly grounded.

N.E. Terminal strip for remote voltage control pot. when used.

N.F. Alternative 500 amp positive terminal connection provided on DC-1000 models above code 9500 only.

Above diagram shows electrode connected positive. To change polarity, turn power off, reverse the electrode and work leads at the power source and position the switch on power source to proper polarity.

N.D. Connect the LN-9 control cable ground lead to the frame terminal

marked near the power source terminal strip. The power source must be properly grounded.

N.E. If using an older automatic control cable with leads 75, 76, 77; Connect lead 75 to #75 on terminal strip, connect lead #76 to #74 on terminal strip, connect lead #77 to #73 on terminal strip.

N.F. The LN-9 voltage control jumpers must be connected as follows (Refer to LN-9 operating manual): White jumper on voltage board to pin “S”. Blue jumper on voltage board (later units only) or on start board (earlier units). To pin “B”.

Above diagram shows electrode connected positive. To change polarity, turn power off, reverse the electrode and work leads at the power source, position the positive-negative switch on the power source to correspond to the polarity of the electrode cable connection. Refer to LN-9 operating manual for required polarity connections.

N.G. Set the DC-1000 controls as follows: Set the control switch to “Output Control Remote”. For Submerged Arc Processes, set the mode switch to “C.V. Innershield”.

N.H. Alternative 500 amp positive terminal connection provided on DC-1000 models above code 9500 only.
