Daktronics CE-1010 - Manual (Page 13)

Mechanical Installation 2-3
Each section is labeled with an address and X-Y coordinate. Make sure that the
proper section is mounted to the Z-bracket in the proper place.
Make sure that the mounted Z-brackets have screws attached vertically to each
end to prevent the display sections from sliding off. This is discussed and
illustrated in the included install kit drawings.
2.5 Display Ventilation Requirements
Fresh air inlets and exhaust vents should not be obstructed in any way. Using the
Daktronics suggested mounting methods will ensure proper ventilation. If using a
different mounting method, consult a Daktronics sales representative for clearance
requirements regarding the particular display. If ventilation requirements are not
met, the display warranty will be void.
