Warning Before wiring and inspections, 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, when confirming whether the charge lamp is
off or not, always confirm it from the front of the servo amplifier.
Warning Any person who is involved in wiring and inspection should
be fully competent to do the work.
