Insert the wire all the way to the back of the wire insertion opening.
Check that the sheath of the wire is inserted into the wire insertion opening, and that the end of
the conductor has passed through the connection part.
3
Insert a screwdriver into the reset opening and pull back the operation lever lightly.
A click will be heard and the operation lever will return to its normal position.
4
Lightly pull the wire to confirm that it is connected properly.
Precautions for Correct Use
To remove a wire, push in the operation lever, check that the operation lever has locked, and
then pull out the wire. Also, after removing the wire, always return the operation lever to its
normal position.
For SmartClick Connectors, insert the Connector all the way and turn it approx. 1/8 of a turn. Torque
management is not required.
For screw connections to M12 connectors, tighten the lock on the M12 connection sufficiently with your
hands (tightening torque: 0.39 to 0.49 N·m).
If the lock is not tightened sufficiently, the degree of protection may not be achieved and the connector
may become loose due to vibration. Never use pliers or other tools to tighten the lock. Doing so may
damage the connector.
