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.
Figure 2: U-Bolt installation
Loosely screw on the nuts on the ends of the U-bolts. You will tighten these later
during final mounting. Final assembly is shown in Figure 3.
