Packing
(1)
Please pass Cap, Clamping member, and Rubber
bush through the cable.
Please peel off the cable covering from
the verge by the length of 85mm.
(2)
Please make the shield line asunder.
Please wrap an asunder shield line
as shown in left figure.
(3)
Please pass Shield-ring through the cable.
Please peel off the cover of the core wire by 5mm.
Please use solderless terminal with insulating
coating of Stick-type by three (brown, yellow, and
white) core wires.
A green core wire must use the pressure terminal of
R type(R1.25-4).
(4)
Please pass Body and Packing through the cable, and
install it so that the shield line may surely come
in contact with the Shield-ring.
