APPENDIX
(b) Selection example of MCCB and fuse
Use T class fuses or molded-case circuit breaker (UL489 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 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.
