Do not short-circuit the conductive layer and the
terminals (A, B, C, G, and T*
1 ).
Slide black FEP (fluorinated ethylene propylene)
tubing over the inner shield drain wire C and blue
FEP tubing over outer shield drain wire G until
the tubing cannot be slid any further, and then cut
off the tubing leaving 5 mm (0.2 in.) of the drain
wires exposed.
Slide heat shrinkable tubing over the cable end so
that the tubing covers the braided shield and
overlaps both the polyethylene jacket and loose
wires A, B, C, G, and T*
1 .
Slide a short piece of heat shrinkable tubing over
each of wires A, B, C, G, and T*
1 . Install a crimp-on
terminal lug at the tip of each wire. Crimp and
solder each lug.
Attach an identification label to the end of the cable.

Strip off the outer polyethylene jacket, outer braided
shield and inner jacket, and inner braided shield as
per the dimensions as shown.
Cut of the black conductive layers(convering the
two wires) completely, as per the dimensions below.
Twist each of the conductor and drain wires so that
there are no free strands.
Strip off about 5 mm (0.2 in.) of insulation for each
of wires A, B, and T*
1 , and twist the strands of each
wire.
Slide each short piece of heat
shrinkable tubing over the crimp sleeve. Heat all
pieces of heat shrinkable tubing with a heat blower
or dryer.

NOTE
Check that the insulation resistance between each
wire including the inner shield is 10M or greater at
500V DC. Ensure that both ends of the wires are
disconnected (open-circuited) during the check.
NOTE
In case that the cable end
fi nish parts assembly is
necessary after delivery,
contact your nearest
Yokogawa sales offi ce or the
sales representative from
which you purchased the
product.
CAUTION
Do not touch the '' conductive layer"
(black area covering the signal cables
A and B) to the converter case,
terminal, and other leadwires. If it is
touched, operation of the converter
may be incorrect. When the cable is
terminated, remove the conductive
layer properly.
