The recommended installation sequence is:
1. Mount the bracket to the pole using
either M16 bolts (torque 52 lb-ft
(70 Nm)), 5/8” bolts (torque 50 lb-ft
(68 Nm)) or straps taking into account
orientation guidelines described in RCU
location and orientation.
2. On the ground, assemble the bird roost
guard and the U-channel to the bracket
using the screws provided leaving the
screws loose.
3. Mount the panel on the U-channel and
orientate. Fit the M8 bolts and torque to
11 lb-ft (15 Nm). The solar panel can be
installed at two different angles. The
best angle of the panel depends upon
the latitude of the site as follows:
a. For latitudes <30°, install solar
panel at 30° angle to the
horizontal.
b. For latitudes >30° and <45°, install
the solar panel at 45° angle to the
horizontal.
Most of the U.S. is located between 30°
and 45°. Southern areas (southern
portions of Texas, Louisiana, Florida and
all of Hawaii) are less than 30°.
Northern states (e.g., Washington to
Maine and Alaska) have latitudes of over
45°.
4. Tighten all bolts and screws.
5. Connect grounding wires as required in
Grounding section on page 35.
6. Connect the panel output leads to the
RCU.
