them directly or close to combustibles will lead to smoke or a fire.
Always connect a magnetic contactor between the power supply and the power supply (L1/L2/L3) of the
servo amplifier, in order to configure a circuit that shuts down the power supply on the side of the servo
amplifier’s power supply. If a magnetic contactor is not connected, continuous flow of a large current may
cause smoke or a fire when the servo amplifier malfunctions.
Always connect a molded-case circuit breaker, or a fuse to each servo amplifier between the power
supply and the power supply (L1/L2/L3) of the servo amplifier, in order to configure a circuit that shuts
down the power supply on the side of the servo amplifier’s power supply. If a molded-case circuit breaker
or fuse is not connected, continuous flow of a large current may cause smoke or a fire when the servo
amplifier malfunctions.
When using the regenerative resistor, switch power off with the alarm signal. Otherwise, a regenerative
transistor malfunction or the like may overheat the regenerative resistor, causing smoke or a fire.
When you use a regenerative option with an MR-JE-40C to MR-JE-100C, remove the built-in
regenerative resistor and wiring from the servo amplifier.
