• Selection example of MCCB and fuse
Use T class fuses or molded-case circuit breaker (UL 489 Listed MCCB) as the following table. The T class fuses and
molded-case circuit breakers in the table are selected examples based on rated I/O of the servo amplifiers. When you select
a smaller capacity servo motor to connect it to the servo amplifier, you can also use smaller capacity T class fuses or molded-
case circuit breaker than ones in the table. For selecting ones other than Class T fuses and molded-case circuit breakers
below and selecting a Type E Combination motor controller, refer to the following.

• Power supply
This servo amplifier can be supplied from star-connected supply with grounded neutral point of overvoltage category 
(overvoltage category  for 1-phase servo amplifiers, MR-J4-03A6, and MR-J4W2-0303B6) set forth in IEC/EN 60664-1. For
the interface power supply, use an external 24 V DC power supply with reinforced insulation on I/O terminals.
In case of MR-J4-03A6 and MR-J4W2-0303B6, use DC power supplies of reinforced insulation type. For the main circuit
power, use UL listed (recognized) 48 V DC/24 V DC power supplies which can generate more than 1.2 A/2.4 A per axis.
