What are the requirements for the installation space of the fan?

If the installation location is too narrow, it will affect the performance of the fan, and if it is too wide, it will reduce the space utilization rate and the ventilation and heat dissipation effect. So what is the specific installation range?

How to connect the terminals of the EC new fan and the new fan?

we talked about that the input port and output port of the old model are separated, and the input end is divided into analog input and digital input. The biggest difference between the new model and the old model is that the new model combines the input and output settings together. There are three IO ports, namely IO1, IO2 and IO3. I represents input (IN) and O represents output (OUT). So what are the specific functions of these three IO ports?
