7114-NHR-147 ebmpapst perfect fit for ABB inverter

Installation steps:

Prepare for power failure: switch off and discharge the ACS800 power supply to ensure safe operation.

Remove the old fan: Remove the fixing screws and power connector of the original fan and take it out gently.

Fit check: check whether the mounting holes, size (usually 172×150×55mm) and voltage (24V DC) of 7114NHR-147 are compatible with ACS800.

Installation fixing: Align the new air blower to the cooling duct and fasten it with screws to ensure no vibration loosening.

Wiring test: Connect the power cable to the corresponding interface of the inverter control board, and observe whether the fan steering and speed are normal after power on.

Advantages of 7114NHR-147 ebmpapst:

High-efficiency heat dissipation: optimised blade design, air volume up to 230m³/h, significantly reducing the temperature rise of the IGBT module and prolonging the life of the inverter.

Low noise operation: Adopting ball bearing and dynamic balancing technology, the noise is lower than 55dB, suitable for quiet environment.

Long life design: IP54 protection level, high temperature and dust resistance, MTBF (Mean Time Between Failure) over 60,000 hours.

Strong compatibility: designed for ACS800 duct structure, installation without modification, plug and play.

Energy-saving and stable: power consumption is only 28W, supports PWM speed regulation, intelligently matches the heat dissipation demand, and reduces energy waste.
