(2) Cable connection procedure
(a) Fabrication on cable insulator
Refer to table 3.1 and 3.2 for stripped length of the 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 for connection with the connectors. When using a ferrule, select a ferrule
and crimping tool listed in the table below.

(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 wire
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 CNP2 connector for 2 kW and 3 kW.
1) Push down the open tool.
3) Release the open tool to fix the wire.
2) Insert the wire.
