Input Current Figure 1: Auto Start Protection t Run Locked Rotation Detector Signal (White Wire) The rotation detector signal is used to detect if the fan motor is operating or stopped. The output will be logical low (VL) when fan is operating and be logical high (Vcc) when fan motor is locked. (See Figures 2~3 below).

The failure to use such a device may result in smoke, fire, electric shock by insulation degradation in cases of motor lead short circuit, overload, or over voltage, and/or other failure. 3. CUI recommends installing a protection device to the product or application in which this fan is installed if there is a possibility of reverse connection between Vdc (+) and GND (-). The failue to install such a device may result in smoke, fire, and/or destruction, although these conditions may not manifest immediately. 4. This fan mush be installed and used in compliance with all applicable safety standards and regulations. 5. Use proper care when handling and/or installing this fan. Improper handling of installation of this fan may cause damage that could result in unsafe conditions. 6. Use proper care during installation and/or wiring. Failure to use proper care may cause damage to certain components of the fan including, but not limited to, the coil and lead wires, which could result in smoke and/or fire. 7. Do not use power or ground PWM to control the fan speed. If the fan speed needs to be adjusted, please contact CUI to customize the product design for your application. 8. For critical or extreme environments, including non-stop operation, please contact CUI and we will gladly provide assistance with your product selection to ensure an appropriate cooling product for your application. 9. When building your device, please examine thouroughly any variation of EMC, temperature rise, life data, quality, etc. of this product by shock/drop/vibration testing, etc. If there are any problems or accidents in connection with this product, it should be mutually discussed and examined. 10. Use proper care when handling these fans. Components such as fan holders or bearings may be damaged, if touched with fingers or other objects. Additionally, static electricity (ESD) may damage internal circuits of the fan. 11. Do not operate these fans in proximity to hazardous materials such as organic silicon, cyanogens, formalin, phenol, or corrosive gas environments including, but not limited to, H2S, SO2, NO2, or Cl2. 12. CUI recommends that you protect these fans from exposure to outside elements such as dust, condensation, humidity, or insects. Exposure of this fan to such elements may affect its performance and my cause safety hazards. CUI does not warrant against damage to the product caused by outside elements. 13. The fans must be installed properly and securely. Improper mounting may cause harsh resonance, vibration, and noise. 14. Do not store these fans in an environment with high humidity. These fans must be stored in accordance with the specified storage temperature. 15. CUI reserves the right to use components from multiple sources at its discretion. The use of components from other sources will not affect the specifications as described herein. 16. The life expectancy of these fans has not been evaluated for use in combination with any end application. Therefore, the life expectancy that relate to these fans are only for reference. cui.com For more information, please visit the product page.
