4. SIGNALS AND WIRING
Wire the power supply and main circuit as shown below so that the servo-on (RYn0) turns off as soon as alarm
occurrence is detected and power is shut off.
A no-fuse breaker (MCCB) must be used with the input cables of the power supply.
(1) For 3-phase 200 to 230VAC power supply to MR-J3-10T to MR-J3-350T

. (Factory-wired.) When using the power factor improving DC reactor, refer to section 14.11.
2. Always connect P( ) and D. (Factory-wired.) When using the regenerative option, refer to section 14.2.
3. For encoder cable, use of the option cable is recommended. Refer to section 14.1 for selection of the cable.
4. For the sink I/O interface. For the source I/O interface, refer to section 4.8.3.
5. Refer to section 4.10.
6. Configure the circuit which shuts off main circuit power with external sequence at forced stop (EMG) off.
7. Use a magnetic contactor with an operation delay time (interval between current being applied to the coil until closure of
contacts) of 80ms or less.
