Section 2: Mechanical Installation
The Daktronics product manager’s engineering staff must approve any changes that
may affect the weather tightness of the display. This includes, but is not limited to,
the border shrouding, back sheets, cooling fans, fan filters and filler panels. Before
making ANY modifications to the weather tightness of the display, submit detailed
drawings of the changes to our engineering staff for evaluation and approval or the
warranty will be null and void.
Appendix C contains two copies of the Installation Quality Checklist. Keep one copy
and send the other to Daktronics at the address listed on the form.
CAUTION: Fully attach backsheets to the display cabinet, with all of the screws,
prior to lifting the display with the eye bolts. The backsheets provide structural
support to the cabinet. Lifting the display with the backsheets removed may cause
the cabinet members to twist, compromising the structural integrity and/or
squareness of the display frame. If the display frame is not square, normal
waterproofing measures may prove inadequate, leading to moisture related problems
for the electronics.
2.1 Mechanical Installation Overview
Because every installation site is unique, there is no single Daktronics-approved procedure for
mounting Series 1600 large matrix displays. The information contained in this section is general
information only and may or may not be appropriate for this particular installation.
All decisions regarding the mounting of this display must conform to the specifications and
guidelines in this section.
Read both the mechanical and electrical installation sections of this manual before beginning
any installation procedures.
Series 1600 large matrix displays can be either Sectional Displays or Full Cabinet Displays.
Sectional Displays: Larger displays built and shipped in sections, which require assembly at the
installation location. The display sections bolt to a mounting structure and to each other. Display
sections must be bolted to each other horizontally and vertically to ensure uniform module spacing.
Daktronics may or may not install the display border shroud at the factory.
Full Cabinet Displays: Shipped in one piece as a complete unit.
2.2 Support Structure Selection/Design
An adequate support structure must be present if this display is to mount in a safe and stable manner.
Support structure design may be dependent on mounting method, display size and weight as well as
the size and weight of any additional signs attached to the display or mounting structure. Display
height and wind loading are also critical factors. Continuously support the bottom of the display.
It is the installer’s responsibility to ensure the mounting structure and mounting hardware is capable
of supporting the display.
