3Installation 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:
oPole and Footing material
oStainless steel banding and banding clips and
application tool or adjustable steel banding
for installing Battery Box & Sign
oAssorted hand tools.
oSocket set and drive handle.
oU-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.
http://www.srrb.noaa.gov/highlights/sunrise/sunrise.h
tml
Set the bracket angle using your current latitude +15
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

Shown with optional beacon cable set, see your
display installation manual for other display size
connections).
Figure 3-1. 15” Display ECS Access Panel
a. Route the supplied 5 foot conduit with DC
power wire and ground cable from the
battery box to the bottom of the ECS. It can
be installed at either the top or bottom of the
battery box, but if installed at the bottom,
extra wire (#14 Red and Black, not supplied)
will have to be spliced in to make up the
extra length used.
b. At the bottom of the ECS, remove the access
panel and route the power cord and green
ground wire through the conduit receptor
located on the access panel. Plug in the
power connector to the power connector
receptacle located inside the ECM. Connect
the ground wire to the green wire located
inside the ECS.
c. Secure the conduit to the conduit receptor.
d. Install the access panel cover.
Route solar panel wires to the battery box. See
Figure 3-2.
a. Remove the battery box cover.
b. In the battery box, remove the two right side
screws and loosen the two left side screws on
the solar charger.
c. Pull the charger away from the mounts and
allow it to hang out of the way.
d. Remove the insulation panel that was under
the charger and store it in a safe place. (This
gives access to the conduit fittings from
inside of the enclosure.)
e. Install the wires and cable from the sign and
solar panel (solar panel left, sign right)
through the provided conduit fittings, and
then tighten the conduit connectors onto the
pre-installed fittings.
f. Replace the insulation panel removed earlier,
and re-install the solar charger.
Figure 3-2. Remove Solar Charger from
Battery Box
Connect ECS wires to solar charger in battery
box. See Figure 3-3.
a. Connect the ground wire from the display to
the solar charger mounting screw.
b. Connect the ECS power cable lead with the
white stripe to the solar charger terminal
marked “LOAD +”, which is terminal 6.
c. Connect the other ECS power cable lead to
the terminal marked “LOAD –“, which is
terminal 5.
Figure 3-3. Wiring Solar Charger
in Battery Box
Install the batteries in the battery box. Install the
battery Ring Lug stubs onto the batteries first.
Then connect the batteries to their respective
connectors (one set provided per shelf) in the
harness matching orange to orange and black to
black. The operating voltage is 12VDC. At this
point the display has power.
Connect the wires to the solar panel.
a. At the solar panel, make sure the opaque
cloth is still covering the panel.

Solar N-C-S Installation Instructions 029-03748-0000 rev E

b. In multi-panel parallel solar arrays inspect
that blocking diodes are properly installed on
the solar panel terminal blocks (in the solar
panel wiring boxes) to prevent back feeding
on shaded panels.
c. Connect the battery box red wire (+) to the
panel + on the solar panel terminal block.
Connect the battery box black wire to panel
negative in the panel terminal block.
8. Connect the solar panel wires to the solar
charger in the battery box. See Figure 3-3.
a. Make sure the opaque cloth is still covering
the panel.
b. Connect the solar panel red wire to the
positive (+) terminal of the solar charger “SOLAR +”
terminal (4).
c. Connect the solar panel black wire to the
solar charger “SOLAR –“ terminal (3).
Check the panel operation and battery charging using
a volt meter. During daylight hours, if the battery
voltage rises above night levels, then the solar panel
and charger are working.
Monitor the charge process through a full charge. If
the charge voltage is excessive, then the charger may
have failed and will damage the batteries unless
action is taken to disconnect the solar panel until
repairs are made.
The charger is temperature compensated. It is
normal for the charge voltage to be higher when the
weather is cold, and lower when the weather is hot.
The normal full charge voltage varies -28mV per
degree C of deviation from 25°C.
Note: The solar panel only provides power
when illuminated by the sun. If the panel was
covered during installation, remove the cover
before performing this test.
For best results, start with a new fully charged
battery. Never mix old and new batteries. Be sure
to ground the solar panel rack and battery box
properly according to code.
