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

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

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.
