3.3.1 Wiring wind sensors WAA151 and WAV151

Usually both WAA151 and WAV151 wind sensors are connected to the junction box of the cross
arm WAC151 simultaneously.

The following figure shows the standard wiring diagram for WAA151 and WAV151. The
thermostat switch in the upper left corner is always included for temperature control of the

shaft heating power.
