CONNECTING THE LN-8 OR LN-9 TO THE CV-655
(TERMINAL STRIP)
1.
Set the CV-655 POWER toggle switch to the OFF
(0) position.
2.
Disconnect main AC input power to the CV-655.
3.
Connect the wire feeder control cable leads to the
CV-655 terminal strip as shown in Figure C.4.
4.
Connect the wire feeder control cable ground lead
to the frame terminal marked .
5.
Extend wire feeder control cable lead #21 so it can
be connected directly to the work piece.
a. Make a bolted connection using AWG #14 or
larger insulated wire. Tape the bolted connec-
tion with insulating tape.
b. An S-16586- X remote voltage sensing work
lead is available for this purpose.
c. Keep the #21 lead electrically separate from
the work cable circuit and connection.
d. Tape the #21 lead to work cable for ease of
use.
6.
Connect LN-9 wire feeder control jumpers on
Voltage Control board. See LN-9 Operator’s
Manual.
NOTE: The connection diagram shown in Figure C.4
shows the electrode connected for positive
polarity. To change polarity:
a. Set the CV-655 POWER toggle switch to the
OFF (0) position.
b. Move the electrode cable to the negative (-)
output terminal.
c. Move the work cable to the positive (+) output
terminal (High inductance or low inductance
as needed).
d. Connect control cable lead #21 to “+21” on
the terminal strip.
7.
Set the OUTPUT CONTROL switch to the
“Remote” position and the OUTPUT TERMINALS
switch to the “Remote” position.
