Note 1. Alphabets in the table indicate crimping tools. For crimp terminals and applicable tools, refer to (2) in this section.
2. To connect these models to a terminal block, be sure to use the screws that come with the terminal block.
3. Wires are selected based on the highest rated current among combining servo motors.
4. Be sure to use the size of 2 mm 2 when corresponding to the IEC/EN/UL/CSA standard.
