(1) Tightening torque
Tighten the terminal block screws within the following specified torque range.
Tightening the screws too much may damage the module case.
The following table shows applicable solderless terminals to be connected to the terminal block. For wiring, use
the wire and tightening torque as specified in the table below. Use UL-listed solderless terminals, and for
processing, use the tool recommended by their manufacturers. Note that a solderless terminal with an insulation
sleeve cannot be used.
Screw type Tightening torque range
Terminal screw (M3) 0.43 to 0.57N⋅m
Terminal block mounting screw (M3.5) 0.68 to 0.92N⋅m
