5.2.1 Install U-bolts and mounting pole
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 Figure 2, 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 2.
