(b) 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,
refer to section 11.10.

(c) Power supply
This servo amplifier can be supplied from star-connected supply with grounded neutral point of
overvoltage category III (overvoltage category II for MR-J4-03A6 and MR-J4W2-0303B6) set forth in
IEC/EN 60664-1. However, when you use the neutral point for single phase supply, a reinforced
insulating transformer is required in the power input section. 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
to main circuit, control circuit, and UL listed (recognized) 48 V DC/24 V DC power supplies which
can generate more than 1.2 A/2.4 A per axis.
