4.3 Crimp-style terminal
For I/O wiring, use crimp-style terminals of the following dimensions.
Use a crimp-style terminal in a status in which no force is applied on the cable.
4.4 Module terminal screw
Tighten the terminal screws (M3 screws) on the terminal block with a tightening
torque of 42 to 58 N⋅cm.

*4 This index indicates the degree of conductive generating substances in the
environment in which the module is used. The degree of contamination 2
indicates that contamination is caused by generation of only non-conductive
substances.
In this degree, however, temporary conduction may be caused by accidental
condensation.
