CONNECTING THE POWER INPUT
CABLE ASSEMBLY TO THE LN-9NE or
LN-9SE
The hand crank drive rolls will feed all the wires used
on the extension. The rolls have been stenciled for
identification.
1. Position the extension assembly cable so that the
amphenol plug with the threads on its O.D. can be
attached to the amphenol end of the power input
cable. Attach the opposite end to the wire drive
unit. See Figure A.3.
2. Attach the amphenol extension assembly control
cable (the one with threads on its O.D.) to the con-
nector on the input cable assembly.
3. Remove the screws holding the cable clamp locat-
ed near the rear of the wire reel base. Put the con-
trol cable and the electrode cable under the clamp
and install the screws. (On cables with more than
one electrode cable, leave the junction between the
cables and the single 4/0 stub behind the clamp so
that only the single electrode lead is under the
clamp.) Connect the electrode cable of the input
cable assembly to the brass block on the hand
crank.
4. Insert the connector on the conductor sheath of the
extension assembly into the brass block of the hand
crank assembly. Tighten the locking screw with a
3/16 hex allen wrench.
5. At the wire drive unit, connect the amphenol of the
extension control cable to the receptacle on the
back of the LN-9.
6. Remove the ingoing guide tube from the rear brass
block and then plug the connector of the conductor
sheath into the brass block. Tighten the locking
screw with a 3/16" hex allen wrench. The guide
tube removed is not used when the extension
assembly is installed.
