Daktronics Rear-Ventilated GalaxyPro GP3 Series - Manual (Page 8)

3 Installation Preparation
Section 2: Installation Preparation
This section explains what to consider before installing a Daktronics GalaxyPro ® GP3 display.
Follow all guidelines and safety precautions in this manual when installing the display. Do not modify
the display or control system in any manner without the written permission of Daktronics’ engineering
staff.
Any unauthorized modifications will nullify the display warranty.
2.1 Pre-Installation Checklist
• The display was not damaged during shipping
• The mounting structure will provide a straight and square mounting frame for the display
• The support structure can carry the weight of the display and meets local and national codes
• There is clearance at the back of the display to allow unobstructed airflow – refer to shop
drawing for ventilation specifications
• Ensure proper power is available at sign structure – refer to shop drawing for display power
requirements
• The display cabinet has no holes (accidental or intentional) that will allow water to enter the
display
• All display modules are fully latched into the display cabinet
2.2 Structure Requirements
Support structure design depends on mounting method, installation height, display size, and
weight. Because every installation site is unique, Daktronics approves no single procedure for
mounting displays.
Things to consider prior to installation:
• Display structure and mounting must not obstruct airflow - refer to shop drawing for
ventilation space requirements
• All T-clips must be used for mounting to structure
• Light sensor must not be obstructed to maintain proper display dimming
For additional questions about display mounting requirements and specifications, refer to the
display shop drawing or contact Daktronics Technical Support at 800-DAKTRONICS (800-325-
8766).
2.3 Electrical Requirements
Important Note: Size circuits according to local and national codes so the power distribution
system delivers full-load power to the display while maintaining a voltage within 5 percent of the
nominal voltage.
