Precautions
Tighten the module fixing screws and others within the specified torque range.
Screw type
*1
Module fixing screw (M3)
Terminal screw (M3)
Terminal block mounting screw (M3.5)
*1 The hook on the top of the module allows the module to be fixed to a base unit easily. In a place where there is a lot of vibration,
however, fixing with module fixing screws is recommended.
The following table lists an applicable solderless terminal to be connected to the terminal block. When wiring, use the wire and
tightening torque applicable to the table. Use UL listed solderless terminals and, for processing, use the tools recommended
by their manufacturer. Note that a solderless terminal with an insulation sleeve cannot be used.
