Mechanical Installation
Important Notes:
•
Read and understand these instructions before installing the display.
•
Properly ground the display with a ground rod at the display location.
•
Disconnect power when servicing or not using the display.
•
Do not modify the display structure or attach any panels or coverings.
2.1 Support Structure Design
FL-4000 displays are designed to be mounted into a larger sign structure. The sign must
prevent water from entering the back and sides of the display. Daktronics is not responsible
for operational failure due to water entering the sign.
Daktronics is not responsible for the support structure or for quality of the mounting
hardware used to attach the displays to the support structure. Structure and attachment must
conform to all applicable building codes.
Important Notes:
•
It is the customer’s responsibility to ensure the installation will meet local standards.
•
The mounting hardware must support all components.
•
Be sure that any sprinkler systems near the display are pointed in a direction as to
not spray the front of the display.
2.2 Ventilation and Temperature Requirements
Fuelight
™
Petroleum Price digit displays are front ventilated. The display must NOT be fully
enclosed inside a support structure or sign or behind a sign face of plastic, glass, or other
material. The front of the display must be exposed to the air to allow for convection cooling.
Fuelight
™
Petroleum digit displays are designed to operate in ambient temperatures ranging
from -40
o
F to +120
o
F. However, the overall sign structure should be designed and ventilated
in a way to keep the interior of the sign cabinet at a temperature not to exceed 140
o
F.
Items to consider when designing a sign package to house LED price displays include:
•
Solar gain from the black face of the price displays
•
Solar gain from other sign cabinet surfaces
•
Heat gain from electronics inside the displays
•
Passive or active airflow with adequate intake and exhaust areas
Daktronics is not responsible for high-temperature failure due to inadequate ventilation.
