Install U-bolts and metal plate
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 5 on the right side, 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 (opposite side of solar panel). 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.
