For control circuit power supply
When the wiring for the control circuit power supply (L11/L21) is thinner than that for the main circuit power supply (L1/L2/L3),
install an overcurrent protection device (molded-case circuit breaker, fuse, etc.) to protect the branch circuit.

*1 To comply with the IEC/EN/UL/CSA standards, refer to the MR-J5 Safety Instructions and Precautions for AC Servos (IB(NA)-0300391)
for selection of molded-case circuit breakers and fuses.
Using servo amplifier with DC power supply input
When using a fuse instead of the molded-case circuit breaker, use the one having the specifications given in this section.

*1 Use a molded-case circuit breaker that has operation characteristics equal to or higher than Mitsubishi Electric general-purpose
products.
*2 Use the magnetic contactor with an operation delay time (interval between current being applied to the coil until closure of contacts) of
80 ms or less.
