Cable connection procedure
■Fabrication on cable insulator
Refer to the following for stripped length of cable insulator. The appropriate stripped length of cables depends on their type,
etc. Set the length considering their status.

Twist strands lightly and straighten them as follows.
Loose and bent strands
Twist and straighten
the strands.
You can also use a ferrule to connect with the connectors. When using a ferrule, select a ferrule and crimping tool listed in the
table below.

■Inserting wire
Insert only one wire or ferrule to each wire insertion hole.
Insert the open tool as follows and push it down to open the spring. While the open tool is pushed down, insert the stripped
wire into the wire insertion hole. Check the wire insertion depth, and make sure that the cable insulator will not be caught by
the spring and that the conductive part of the stripped wire will not be exposed.
Release the open tool to fix the wire. Pull the wire lightly to confirm that the wire is surely connected.
In addition, make sure that no conductor wire sticks out of the connector.
The following shows a connection example of the CNP3 connector for MR-J4-200GF(-RJ) and MR-J4-350GF(-RJ).
1) Push down the open tool.
3) Release the open tool to fix the wire.
2) Insert the wire.
