Wiring

18-point screw terminal block type module

Precautions
• When wiring the terminal block, be sure to use a solderless terminal with a width of 0.8mm or less. In addition, one terminal
part allows connection of up to two solderless terminals.
• A solderless terminal with an insulation sleeve cannot be used for the terminal block. To prevent a short-circuit due to a
loose terminal block screw, coating the wire connection part with a mark tube or insulation tube is recommended.
• For the wire to be connected to the terminal block, use the following.
Applicable wire size
0.3 to 0.75 (22 to 18 AWG) (stranded wire)
Outside diameter: 2.8mm or less
• Use the UL listed solderless terminal, R1.25-3.
• Tighten the terminal block screws within the following specified torque range.
Screw
Terminal screw (M3)
Terminal block mounting screw (M3.5)
*1 Use the wire of 0.75 or smaller. If the wire of larger than 0.75 is used, the sideways overhang of wiring becomes large, contacts
with the terminal block or connector of an adjacent module, and results in applying stress to the module. Note that the wire of 0.3 to
1.5 (22 to 16 AWG) can be used when a spring clamp terminal block (Q6TE-18SN) is used instead. To use a wire of larger size than
the one described in the above table, take a measure by using FA goods of Mitsubishi Electric Engineering Co., Ltd. (such as FA-
TB161AC+ FA-CBL20D).
