2.5.3 AC/DC Power Supply and Power Supply Input Capacitor
2-14
The following table shows the fuse or the molded-case circuit breaker specifications.
The SGDJ SERVOPACK does not include a protective grounding circuit. Install a ground-fault protector to
protect the system against overload and short-circuit or protective grounding combined with the molded-case
circuit breaker.
2.5.3 AC/DC Power Supply and Power Supply Input Capacitor
The SGDJ SERVOPACK requires DC power supply. Select an AC/DC power supply that corresponds with the
voltage of the SERVOPACK. The following table shows the recommended power supply and the power supply
input capacitor.
* Use a power supply with double insulation that is certified and meets safety standards (UL1950 or EN 60950).
Note: To limit the voltage variation of the power supply that results from changes in the load of the servomotor,
insert the power supply input capacitor as close as possible to the SERVOPACK so that it is parallel to the
output side of the AC/DC power supply.
