The wires to connect the spring clamp terminal block are described below.
Number of wires per terminal
One wiring
■Wire end treatment
Strip the cable about 10mm from the tip to connect a wire ferrule at the stripped area. Failure to do so may result in electric
shock due to the conductive part. If the wire strip length is too short, it may result in the poor contact to the spring clamp
terminal part. Depending on the thickness of the sheath, it may be difficult to insert into the insulation sleeve, so select the
wires by referring to the appearance diagram.
Strand wire/single wire
10 mm
Check the shape of the wire insertion opening with the following chart, and use the smaller wire ferrule than the described
size. Also, insert the wire with care so that the wire ferrule is in proper orientation. Failure to do so may cause the bite of the
terminal and the damage of the terminal block.

■Connection and disconnection of the cable
• Connection of the cable
Fully insert a cable whose end has been properly processed into the wire insertion opening.
If the cable cannot be inserted with this procedure, fully insert the cable while pushing the open/close button with a flathead
screwdriver having a tip width of 2.0 to 2.5mm. After fully inserting the cable, remove the screwdriver.
