*1 When using the servo amplifier as an IEC/EN/UL/CSA standard compliant product, refer to "MR-J5 Safety Instructions and Precautions
for AC Servos".
*2 Use a magnetic contactor with an operation delay time (interval between current being applied to the coil until closure of contacts) of 80
ms or less.
*3 The molded-case circuit breaker is the same regardless of whether a power factor improving AC reactor is used.
*4 Use a molded-case circuit breaker that has operation characteristics equal to or higher than Mitsubishi Electric general-purpose
products.
