Do not short - circuit the conductive layer and the
terminals.
Insert black FEP insulation tubing over inner shield
until it stops inside the braided shield.
Cut the tubing off leaving only 5mm(0.2in) of the
inner shield exposed.
Remove 5mm(0.2in) of insulation from the tips of
the two wires.
Insert the heat-shrinkable tubes as shown.
Put heat-shrinkable tubes on yellow
(*1)
, red, white,
black.
Crimp the chip to each wire end and then solder.
Shrink the heat-shrinkable tubes by heating with a
drier etc.
Affix the label as shown.
Confirm that the insulation resistance between each
wire including the inner shield is 10Mohm or greater
at 500VDC. Maintain both ends of the wires
disconnected(open - circuited) during the insulation
resistance test.

Remove the outer polyethylene jacket, outer
braided shield and inner jacket, inner braided shield
as per the dimensions below.
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.
Remove the red and white insulation as per the
dimensions below. Twist the outer drain wire and
the inner drain wire each other.

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.
