Connection of converter unit and servo amplifier (MR-J4 series)

When introducing a fuse to the DC power supply wiring between the converter unit and the servo amplifier,
use a wire size that takes the protection coordination between the wires and the fuse into consideration.
The following shows the wires used for wiring. Use the wires given in this section or equivalent wires.
