Mitsubishi Electric MELSERVO-J4 Series Instruction Manual page 581

The following shows representative configuration examples to conform to the IEC/EN/UL/CSA standards.
The connectors described by rectangles are safely separated from the main circuits described by circles.
The connected motors will be limited as follows.
• HG/HF/HC/HA series servo motors (Mfg.: Mitsubishi Electric)
• Using a servo motor complied with IEC 60034-1 and Mitsubishi Electric encoder (OBA, OSA)
