SAFETY CONSIDERATIONS
1.
Do not use or operate this fan in excess of the limitations set forth in this specification. 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 specifications.
N
UE
D
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, 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.
TI
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.
ON
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.
SC
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.
DI
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.
