Precautions for Safe Use
When you insert a flat-blade screwdriver into a release hole, press it down with a force of 30
N max. Applying excessive force may damage the terminal block.
Do not tilt or twist the flat-blade screwdriver while it is pressed into the release hole. Doing so
may break the terminal block.
Make sure that all wiring is correct.
Do not bend the cable forcibly. Doing so may sever the cable.
The angle at which you insert a screwdriver in the release holes on the screwless clamping
terminal blocks of the CPU Unit is different from that on the screwless clamping terminal
blocks of NX Units. Check the wiring method for the NX Unit and perform wiring correctly.
Refer to the user’s manual of the specific NX Unit for how to wire an NX Unit.

It is necessary to secure wires to the screwless clamping terminal block depending on the wire types
that are used or the current flows on the wires.
The following table gives the necessity for securing wires.
Use the following procedure to secure the wires.
