7114-NHR-147 ebmpapst is perfectly compatible with ABB frequency converters

Installation steps:

Power off preparation: Turn off the ACS800 power and discharge it to ensure safe operation.

Dismantling the old fan: Remove the fixing screws and power connector of the original fan, and gently remove it.

Adaptation check: Verify whether the installation holes, dimensions (usually 172 × 150 × 55mm), and voltage (24V DC) of 7114NHR-147 match ACS800.

Installation and fixation: Align the fresh air fan with the heat dissipation duct, tighten it with screws, and ensure that there is no vibration or looseness.

Wiring test: Connect the power cord to the corresponding interface of the frequency converter control board, and observe whether the fan direction and speed are normal after power on.

Advantages of 7114NHR-147 ebmpapst:

Efficient heat dissipation: Optimized blade design, air flow reaches 230m ³/h, significantly reducing IGBT module temperature rise and extending frequency converter life.

Low noise operation: using ball bearings and dynamic balancing technology, the noise is below 55dB, suitable for quiet environments.

Long life design: IP54 protection level, high temperature resistance, dust prevention, MTBF (mean time between failures) exceeding 60000 hours.

Strong compatibility: specially designed for ACS800 air duct structure, installation does not require modification, plug and play.

Energy saving and stable: With a power consumption of only 28W, it supports PWM speed regulation, intelligently matches heat dissipation requirements, and reduces energy waste.
