Terminal Block - Mitsubishi Electric MELSEC iQ-R Series User Manual

Terminal block

Precautions
• Tighten the module fixing screws and other screws within the specified torque range.
Screw type
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
applicable wire and tightening torque in 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.

Terminal blocks that have been used on MELSEC-Q series channel isolated pulse input modules can be used
just the way they are. The terminal layout is the same as that of the QD60P8-G.
The terminal blocks for MELSEC-L series terminal blocks, however, cannot be used because of the shape
difference.
