(b) 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-J4-200B(-RJ) and MR-J4-
350B(-RJ).
1) Push down the open tool.
3) Release the open tool to fix the wire.
2) Insert the wire.

3.4 Connectors and pin assignment
POINT
The pin assignment of the connectors is as viewed from the cable connector
wiring section.
For the STO I/O signal connector (CN8), refer to chapter 13.
For the CN3 connector, securely connect the external conductor of the shielded
cable to the ground plate and fix it to the connector shell.

The servo amplifier front view shown is that of the MR-J4-20B or less. Refer to chapter 9 DIMENSIONS for
the appearances and connector layouts of the other servo amplifiers.
The frames of the CN2 and CN3 connectors are connected to the protective earth terminal in the servo
amplifier.
