Section 2: Mechanical Installation
The Daktronics engineering staff must approve any changes made to the display. Before altering the
display, detailed drawings for the proposed modifications must be submitted to the Daktronics
engineering staff for evaluation and approval or the warranty will be rendered null and void.
Note: Daktronics does not guarantee the warranty in situations where the display is not constantly in a
stable environment.
2.1 Installation Requirements
An adequate support structure and mounting hardware must be present to mount the sign in a safe and
stable manner.
It is the installer’s responsibility to ensure the mounting structure and mounting
hardware are capable of supporting the display, and will agree with local codes.
Before beginning the installation process, verify the following:
· The mounting structure will provide a straight and square-mounting frame for the display.
· The mounting structure is capable of supporting the display and will not yield at any unsupported
points after mounting.
· Clearance: 3" of unobstructed space is available below the display for proper ventilation of the
sign. Unobstructed space is needed for eyebolt removal/clearance above the sign. Additional space
may be required depending on the mounting method used.
Correct any deficiencies before installation.
Note: Daktronics is not responsible for the support structure or structural integrity of the mounting
structure.
2.2 Ventilation Requirements
Fans are mounted in the bottom of the sign for ventilation. Maintain a minimum distance of
3" (7.62-cm) below the sign to maintain proper airflow.
If the sign cabinet is completely enclosed:
· 12 square inches of unobstructed opening per module must be provided to ensure adequate
cooling.
· Allowances must be made to compensate for the percentage of material covering the openings in
the structure.
· For adequate cooling, forced ventilation may be required. If air is forced into the enclosed cabinet,
19 cubic feet per minute must be provided per module (12.48" x 12.48 " active area).
If these requirements are not met, the Galaxy sign warranty may be void.
