CONNECTING THE LN-7 TO THE
IDEALARC CV-400 (TERMINAL STRIP)
1. Set the CV-400 POWER toggle switch to the OFF (0)
position.
2. Disconnect main AC input power to the CV-400.
3. Connect the wire feeder control cable leads to the
CV-400 terminal strip as shown in Figure C.4.
4. Connect the wire feeder control cable ground lead to
the frame terminal marked .
NOTE: The CV-400 must be properly grounded.
5. PERFORM THIS STEP ONLY IF THE LN-7 IS
EQUIPPED WITH A METER KIT.
NOTE: If the work cable length is less than 25 feet
and the connections to the work piece are secure,
then wire feeder control cable lead #21 can be con-
nected directly to the CV-400 terminal strip.
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 larg-
er insulated wire. Tape the bolted connection 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 the work cable for ease of
use.
6. Set voltmeter toggle switch to match electrode polar-
ity.
NOTE: The connection diagram shown in Figure C-
4 shows the electrode connected for positive polari-
ty. To change polarity:
a. Set the CV-400 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 ter-
minal.
d. Set the VOLTMETER toggle switch to negative (-).
