N.C. Tape up bolted connection if lead #21 is extended. N.D. Connect the control cable ground lead to the frame terminal
marked near the power source terminal strip. The power source grounding terminal (marked and located near the power source input power connections) must be properly connected to electrical ground per the power source operating manual.
N.A. Welding cables must be of proper capacity for the current and

N.G. If lead #21 is to be connected to the terminal strip, connect to 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".
remote voltage sensing work lead may be ordered for this purpose. N.B. Extend lead #21 from control cable with terminal strip connectors or from 14-pin receptacle using #14 AWG or larger insulated wire

Connect it directly to the work piece keeping it electrically convenience, this extended #21 lead should be taped to the welding work lead. (If the length of work lead circuit is short, and connections can be expected to be reliable, then control cable lead #21 does not need to be extended and can be directly connected to terminal #21 on the terminal strip. Note that this is not the preferred connection because it adds error separate from the welding work lead circuit and connection.
