1. To prevent electric shock, note the following.
Before wiring and inspections, turn off the power and wait for 15 minutes or more until the charge lamp of
the servo amplifier is off. Otherwise, an electric shock may occur. In addition, when confirming whether
the charge lamp is off or not, always confirm it from the front of the servo amplifier.
Ground the servo amplifier and servo motor securely.
Any person who is involved in wiring and inspection should be fully competent to do the work.
Do not attempt to wire the servo amplifier and servo motor until they have been installed. Otherwise, it
may cause an electric shock.
Do not operate switches with wet hands. Otherwise, it may cause an electric shock.
The cables should not be damaged, stressed, loaded, or pinched. Otherwise, it may cause an electric
shock.
To prevent an electric shock, always connect the protective earth (PE) terminal (marked
amplifier to the protective earth (PE) of the cabinet.
To avoid an electric shock, insulate the connections of the power supply terminals.
2. To prevent fire, note the following.
Install the servo amplifier, servo motor, and regenerative resistor on incombustible material. Installing
them directly or close to combustibles will lead to a fire or smoke generation.
Always connect a magnetic contactor between the power supply and the power supply (L1, L2, and 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 a fire or smoke generation when the servo amplifier malfunctions.
In order to configure a circuit that shuts down the power supply on the side of the servo amplifier's power
supply, always connect one molded-case circuit breaker or fuse per one servo amplifier between the
power supply and the power supply (L1, L2, and L3) of a servo amplifier. If a molded-case circuit breaker
or fuse is not connected, continuous flow of a large current may cause a fire or smoke generation when
the servo amplifier malfunctions.
When using a regenerative resistor, shut off the power supply using an error signal. Not doing so may
cause a fire or smoke generation when a regenerative transistor malfunctions or the like may overheat
the regenerative transistor.
When using a regenerative option with the MR-JE-40A to MR-JE-100A servo amplifier, remove the built-
in regenerative resistor itself and wiring from the servo amplifier.
Provide adequate protection to prevent screws and other conductive matter, oil and other combustible
matter from entering the servo amplifier and servo motor.
