Cautions
11.1 Cable/connector sets
Purchase the cable and connector options indicated in this section.
Before connecting any option or peripheral equipment, turn off the power and 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, when confirming whether the charge lamp is
off or not, always confirm it from the front of the servo amplifier.
Use the specified auxiliary equipment and options to prevent a malfunction or a
fire.
POINT
The IP rating indicated is the cable's or connector's protection against ingress of
dust and water when the cable or connector is connected to a servo amplifier or
servo motor. If the IP rating of the cable, connector, servo amplifier and servo
motor vary, the overall IP rating depends on the lowest IP rating of all
components.
