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 eyebolts. 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 are built as Sectional Displays or Full Cabinet Displays.
Sectional Displays: Larger displays built and shipped in sections, which are assembled at the
installation location. The display sections are bolted to a mounting structure and to each other. Display
sections must be bolted to each other horizontally and vertically to ensure uniform module spacing. The
display border shroud may or may not be installed 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 be mounted 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. The bottom of the display needs to be
continuously supported.
