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.
