xiiiWARNING Wiring and inspections must be performed only by qualified engineers.There is a risk of electric shock or product failure. Check all wiring and power supplies carefully.Incorrect wiring or incorrect voltage application to the input circuits or output circuits may causeshort-circuit failures. Short-circuit failures can result in equipment damage or personal injury. Connect the power supply input (+24 V and 0 V) to the CN3 connector (power supply input con-nector) on the SERVOPACK.There is a risk of failure or fire.CAUTION Even after you shut OFF the power supply, voltage may still remain in the SERVOPACK. Do nottouch the SERVOPACK until the power indicator goes OFF.There is a risk of electric shock. Observe the precautions and instructions for wiring and trial operation precisely as described inthis document.Failures caused by incorrect voltage application may cause the SERVOPACK to fail, damage theequipment, or result in personal injury. Check the wiring to be sure it has been performed correctly.There is a risk of failure or malfunction. Use the tools recommended by the connector manufacturer if you make any cables yourself.Insufficient crimping may cause wires and connectors to generate heat due to faulty contact, possi-bly resulting in fire. Turn ON the power supply to the SERVOPACK only after all wiring has been completed. Install molded-case circuit breakers and other safety measures to provide protection againstshort circuits in external wiring.There is a risk of fire or failure.NOTICE Whenever possible, use the Cables specified by Yaskawa.If you use any other cables, confirm the rated current and application environment of your modeland use the wiring materials specified by Yaskawa or equivalent materials. Insert cable connectors firmly until the lock mechanisms lock into place.There is a risk of cable disconnection during operation. Do not bundle Power Supply Input Cables or Servomotor Power Cables together with I/O SignalCables or Encoder Cables or run them through the same duct. If you do not place the abovecables in separate ducts, separate them by at least 30 cm.If the cables are too close to each other, malfunctions may occur due to noise entering on the I/OSignal Cables or Encoder Cables.
