3.12 Power line circuit of the MR-J2S-11KB to MR-J2S-22KB
CAUTION
Always connect a magnetic contactor (MC) between the main circuit power supply
and L1, L2, and L3 of the servo amplifier, and configure the wiring to be able to
shut down the power supply on the side of the servo amplifier’s power supply. If a
magnetic contactor (MC) is not connected, continuous flow of a large current may
cause a fire when the servo amplifier malfunctions.
