Mechanical Installation Overview
Because every installation site is unique, Daktronics has no single procedure for mounting Galaxy
signs. This section contains general information only and may or may not be appropria te for your
particular installation.
A qualified installer must make all decisions regarding the mounting of this sign.
Read both the mechanical and electrical installation sections of this manual before beginning
any installation procedures.
2.2
Support Structure Design
Support structure design depends on the mounting methods, sign size and weight. The structure design
is critical; only a qualified individual should mount the sign. Sign height and wind loading are also
critical factors. It is the customer’s responsibility to ensure that the structure and mounting hardware
are adequate. Daktronics is not responsible for the installations or the structural integrity of support
structures done by others.
The installer is responsible to ensure the mounting structure and hardware are capable of
supporting the sign and agrees with local codes.
Before beginning the installation process, verify the following.
•
The mounting structure provides a straight and square frame for the sign.
•
The mounting structure supports the sign without yielding at any unsupported points after
mounting.
•
Clearance: 3
″
of unobstructed space is available below the sign for ventilation. 1 ¼
″
