APPLICATION NOTES
Figure 1: Auto Start Protection
Auto Restart Protection
When the fan motor is locked by an external force, the device will temporarily turn o electrical power to the motor and
restart automatically when the locked rotor condition is released.
Tachometer Signal (Yellow Wire)
The tachometer signal is for detecting the rotational speed of the fan motor. The output will be a square wave when fan
is operating and logical high (Vcc) when fan motor is locked (See Figures 4~5 below). The relationship between RPM &
output pulses from the signal wire is as follows.

SAFETY CONSIDERATIONS
1. Do not use or operate this fan in excess of the limitations set forth in this specication. CUI is not responsible for the
non-performance of this fan and/or any damages resulting from its use, if it is not used or operated in accordance with
the specications.
2. CUI recommends adding a protection circuit to the product or application in which this fan is installed, such as a
thermo-fuse, or current fuse or thermo-protector. The failure to use such a device may result in smoke, re, 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,
re, 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 re.
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 ngers 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 aect 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
specied 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 aect the specications 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.
