Notes

  • *Never touch the inside of the driver or its peripheral devices. Doing so can lead to electric shock or equipment failure.
  • *Do not operate or set up the equipment with damp or wet hands. Doing so can lead to electric shock.
  • *Do not use products that are damaged or missing any components. Doing so can lead to electric shock, fire or injury.
  • *Use only the specified combinations of electric actuator and driver. Other combinations may cause damage to the actuator or driver.
  • *Be careful not to touch or get caught by the workpiece while the actuator is moving. Doing so can result in injury.
  • *Do not connect the power supply or power up the product until you have confirmed that the area of movement in which the workpiece moves is free of hazards and is safe. The movement of the workpiece may cause an accident.
  • *Do not touch the product it is powered on, nor for some time after the power has been disconnected, as it may still be very hot. The high temperature the product reaches may cause burns.
  • *Check the voltage using a voltmeter or other suitable device at least 5 minutes after powering-off when performing installation, wiring and inspection. Doing so can lead to electric shock, fire or injury.
  • *Refer to the SMC catalog for product information other than what is detailed above.
  • *The product image is a representative image only.
