1. To prevent electric shock, note the following
WARNING
Before wiring or inspection, turn off the power and wait for 15 minutes or more until the charge lamp turns
off. Otherwise, an electric shock may occur. In addition, always confirm from the front of the servo
amplifier, whether the charge lamp is off or not.
Connect the servo amplifier and servo motor to ground.
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, you
may get an electric shock.
Operate the switches with dry hand to prevent an electric shock.
The cables should not be damaged, stressed, loaded, or pinched. Otherwise, you may get an electric
shock.

2. To prevent fire, note the following
CAUTION
Install the servo amplifier, servo motor and regenerative resistor on incombustible material. Installing them
directly or close to combustibles will lead to a fire.
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.
