WARNING
Before installing a battery, turn off the main circuit power while keeping the control
circuit power on. Wait for 15 minutes or more until the charge lamp turns off. Then,
confirm that the voltage between P and N is safe with a voltage tester and others.
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.
POINT
The internal circuits of the servo amplifier may be damaged by static electricity.
Always take the following precautions.
