- Page 7 Precautions: (1) Please be careful not to connect the wrong wiring sequence, the wrong wiring will cause the equipment to burn (2) The voltage/current positive output is an active output. Never connect the voltage/current positive output to the positive position of the power supply, which will definitely cause burnout.
- Page 8 2.4Installation method Flange installation is adopted. The threaded flange connection makes the lower pipe fitting of the wind direction sensor firmly fixed on the flange. Four mounting holes are opened on the circumference of the chassis, and bolts are used to tightly fix it on the bracket to keep the entire instrument on The best levelness ensures the accuracy of the wind direction data, the flange connection is convenient to use and can...
