5.3.1 Install wind vane
Push the wind vane onto the shaft on the top of the sensor, until it stops moving further, as shown in figure 1.
Tighten the set screw, with a Philips screwdriver (size PH0), until the wind van cannot be removed from the axle, as
shown in figure 2. Make sure the wind vane spin freely. The wind vane’s movement has a small amount of friction,
which is helpful in providing steady wind direction measurements.
Figure 1 Figure 2
There are four alphabet letters of “N”,” E”,” S” and “W” around the wind direction, representing for the direction of
North, East, South and West. Wind direction sensor must be adjusted so that the directions on the sensor are matching
with your real location. Permanent wind direction error will be installation. when the wind direction sensor is not
positioned correctly during installation.
5.3.2 Install wind cups
Push the wind speed into the shaft as shown in Figure 3.
Tighten the set screw with as shown in figure 4. Make sure the wind speed can spin freely.

5.3.3 Install U-bolts
Installation of the U-bolts, which are in turn used to mount the sensor package on a pole, requires installation of an
included metal plate to receive the U-bolt ends. The metal plate, visible in

has four holes through which the ends of the two U-Bolts will fit. The plate itself is inserted in a groove on the bottom of
the unit. Note that one side of the plate has a straight edge (which goes into the groove), the other side is bent at a 90-
degree angle and has a curved profile (which will end up “hugging” the mounting pole). Once the metal plate is inserted,
remove nuts from the U-Bolts and insert both U-bolts through the respective holes of the metal plate as shown in Figure
5.
