(b) Inserting wire
Insert the open tool as follows and push down it to open the spring. While the open tool is pushed
down, insert the stripped wire into the wire insertion hole. Check the insertion depth so that the cable
insulator does not get caught by the spring.
Release the open tool to fix the wire. Pull the wire lightly to confirm that the wire is surely connected.
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.
