Mechanical Installation 5
Section 2: Mechanical Installation
Read the Mechanical, Power and Signal Installation sections before installing the display(s).
Daktronics’ engineering staff must approve any changes that may affect the weather-tightness of the
display. If any modifications are made, detailed drawings of the changes must be submitted to
Daktronics for evaluation and approval, or the warranty will be null and void.
Daktronics is not responsible for installations or the structural integrity of support structures done by
others. The customer is responsible for ensuring that a qualified structural engineer approves the
structure and any additional hardware.
2.1 Pre-installation Checklist
Verify the following before
installation:
• The display is in good
condition after shipping
and uncrating.
• A straight and square
mounting frame is
provided for the display.
• Height variation in any
4ft. (1.2m) horizontal
section must not exceed
1 /
4
" (6.3mm).
• Adequate support is
provided for the display
so that the structure will
not yield at any
unsupported points after
mounting.
• Leave 4" (102mm) of
unobstructed space above the display so the eyebolt can be removed.
No clearance is required once the eyebolt is removed.
• Maintain clearance around the display to allow unobstructed air flow through the
vents and fans and to allow access to internal components.
• Assure the display cabinet has no holes (accidental or intentional) that could allow
water to enter the display.
• Check that all display modules are fully latched into the display cabinet.
• All horizontal stringers are plumb. Run a plumb bob from the top horizontal stringer
down to the bottom of the display. Refer to Figure 5 for an example.
