Safety Precautions
Refer to Safety Precautions for All Pushbutton Switches/Indicators and Safety Precautions for the A16.
Precautions for Correct Use
Mounting
• When mounting the Case onto the Socket Unit, ensure that the
orientation is correct. Perform mounting with the dimple on the
Case and the TOP mark on the Socket Unit facing in the same
direction.

Case
Screw-less Clamps
Mounting Procedure
1. Strip a length of 10 mm off the end of the wire (allowable range:
10±1 mm).
2. Bunch wire strands together and straighten them.
3. Insert the wire into the insertion hole while pressing the release
button at the side of the hole. (Using a precision screwdriver is
recommended.)
4. Let go of the release button to lock the wire into place.
5. After locking, pull on the wire gently to confirm that it is securely
locked.
Removing Procedure
Socket Unit
Wiring
• When using stranded wire, gather the ends of the strands together
before wiring.
• When wiring, insert the wire until it comes into contact with
something. After wiring is completed, pull on the wires to confirm
that they are connected securely.
• After wiring, ensure that continuous pressure is not applied to the
terminals.
• Refer to internal connections diagrams and confirm the terminal
numbers before performing wiring.
1. Remove wires by pulling them while pressing the release button.
Note: When reusing wires that have already been locked, cut off the end of the
wire and strip the wire again before using.
