FAQ 

1.What is the voltage range that the 20G11TD617AN0NNNNN is compatible with for three-phase input?

The 380 – 480 VAC, voltage fluctuation allowed within ±10%, 50/60 Hz three-phase industrial power grid

2.What are the overall length, width, depth and net weight of model 20G11TD617AN0NNNNN?

Supported. The

• Overall machine dimensions (Frame 8 IP20 open-air air-cooled power unit, units: mm)
• Width: 483 mm × Height: 1041 mm × Depth: 394 mm
• Weight: 112 kg

3.For the 20G11TD617AN0NNNNN model, how many kilowatts of motors should be matched for normal load and heavy load conditions respectively?

The

• Light Load LD: 600HP / 447kW
• Medium Load ND: 500HP / 373kW
• Heavy Load HD: 400HP / 298kW

4.Does the 20G11TD617AN0NNNNN cooling fan support individual replacement? Is there a fan lifespan warning function?

The

• Using multiple sets of modular independent fan components, each set of fans can be disassembled and replaced separately, without the need to replace the entire cooling module.
• Built-in predictive maintenance algorithm can record the cumulative running time of the fan in real time; by reading specific parameters, the lifespan of the fan can be determined. When the lifespan approaches the threshold, an early warning prompt will be triggered to arrange for preventive replacement in advance.
