Fans mounted in the bottom of the sign allow for ventilation. Maintain a minimum distance of 3
O
(7.62cm) below the sign to maintain proper airflow. Refer to the appropriate shop drawing for
additional information.
If the sign cabinet is completely enclosed:
· Provide 6 square inches of unobstructed opening per module to ensure adequate cooling.
· Make allowances to compensate for the percentage of material covering the openings in the
structure.
· For adequate cooling, the cabinet may require forced ventilation. If the enclosed cabinet must use
forced ventilation, it must ventilate at a rate of 10 cubic feet per minute per module (10.6
O x 10.6O
active area).
Failure to comply with these requirements voids the Series AB-1010 sign warranty.

Daktronics typically offers two
display configurations, single face
displays and 2V displays. Figure
6 illustrates each of these two
display types.
A 2V display consists of two
single face units, one master and
one echo. The two sided of this
display may be mounted at any
angle between 0 and 90 degrees.
An interconnect harness used to
power the echo unit is coiled up
inside the master unit. Refer to
Drawing B-139876 for your
sign’s specifications.
2.5 Lifting the Sign
The top of the sign is equipped with eyebolts that are used to lift the unit. Take special care to ensure
that the rated load of the eyebolts is not exceeded. Refer to the information at the end of this section
labeled Eyebolts to determine the allowable load of the eyebolts.
