  • Page 2: Notes On Safety

    It gets an electric shock, short-circuited, and is likely to ignite. This controller is a controller only for the NTN parts feeder (electromagnetic type vibration part supply machine). It is not possible to use it for other usages such as a piezo-electric type parts feeders and the single phase motors.
  • Page 3 Warning It must not be used in a place where it exposes to water, oil or chemicals, or outdoors, or in a place of high temperature and humidity. There is a fear of an electric shock, a fire or a failure. Please do not scratch, pull or forcibly bend the wiring.
  • Page 4 Caution Please do not install it in the place where the vibration or the impact is acting. The controller breaks down. Please refer to the note of caution on the margin below when doing the dielectric breakdown test and megger test (measurement of the insulation resistance by the meggohmmeter). The controller breaks down when making a mistake.
