Installation Requirements
This section describes the components, tools, and
information you must have available before
installing TraffiCalm 140Ah Solar Kit.
3.1
Equipment Requirements
In addition to the Driver Feedback Sign to be
installed, you will need the following suggested
items if you intend to follow these directions:
o
Pole and Footing material
o
Stainless steel banding and banding clips and
application tool or adjustable steel banding
for installing Battery Box & Sign
o
Assorted hand tools.
o
Socket set and drive handle.
o
U-Bolts for installing solar panel
3.2
Installation of Solar Panel
NOTE
It is the installer’s responsibility to
ensure that this installation
complies with local and national
codes.
Use a pole of proper size with an appropriate footing
for the soil and load conditions.
Consult with a
professional Civil engineer for proper pole selection
and footing design for the local area.
Assemble
the solar panel mounting bracket using directions
supplied with the mounting bracket components.
Install the mounting bracket onto the pole with user
supplied (U-Bolts).
In northern latitudes aim the bracket at true South,
not magnetic south. True South is the direction
facing the sun parallel to the shortest shadow of the
day cast by the sign pole, which occurs at “Solar
Noon”. To estimate what time solar noon will occur
in your area go to the NOAA web site with your
longitude and latitude.

Set the bracket angle using your current la15
degrees as measured from horizontal (flat) to the final
position. Example: If the latitude is 45-degrees, set
the panel angle 60-degrees away from flat. You may
be able to get a small amount of additional power by
calculating the set angle using: Latitude *0.9 +29.
This results in a steeper angle than the other method,
optimizing collection around the noon hours during
the winter months, which is when the most solar
energy is available.
Install the solar panel onto the mounting bracket.
3.3
Battery Box Installation
Note: you may wish to cover the solar panel during
daylight installation to prevent accidental short
circuit of energized panel during installation.
Attach the “I” bracket to the battery box using
the included hardware.
a.
Attach the “I” bracket to the center holes of
the battery box using two 3/8-16 x 1-1/4 inch
bolts, two 3/8-inch flat washers, and two
lock washers. (These bolts are hidden when
the battery box is mounted on the pole.)
b.
Install 3/8-16 x 1-inch bolts in the remaining
four holes of the bracket with a flat washer
and a lock washer on each bolt.
Attach the battery box to the pole with user-
supplied 3/4-inch banding and a buckle in two
places (as close to each cross arm of the bracket
as possible).
Connect battery power to the Electronic Control
System (ECS) see Figure 3-1 (15” DFB ECS
