Section 2: Mechanical and Electrical
Installation
Mechanical installation typically consists of installing concrete footings and steel beams and
mounting the display and any accompanying panels to the beams.
Electrical installation consists of the following processes:
Providing power and ground to a disconnect near the display.
Routing power and ground from the main disconnect to the display driver/power
enclosure.
Connecting the display ground to a grounding electrode at the sign location.
Routing the control signal cable from the control location to the sign location.

While Data Master outdoor digit displays are designed for wall or pole mounting, every
installation will be different. Actual site demands will dictate the appropriate mounting
method. Most DataMaster models have finished exteriors, for example, but other
models are designed to be inserted into an existing sign cabinet and require a custom
installation. Lottery displays have a fully finished cabinet, but they are designed to be
used as part of larger sign or billboard.
The engineering drawings referenced above describe several mounting methods, from a
single display on a single column support to multiple displays stacked above one
another in a two-pole installation. The drawings include welding and hardware notes
that will be applicable for most installations.
Note: The drawings suggest mounting methods and are not to be considered as
specifications for construction. The actual mounting hardware and structural design
must be specified by a qualified engineer.
Lifting the Display
DataMaster Lottery displays are shipped equipped with 1 /
2
" eyebolts that are used for
lifting and positioning the modules. Eyebolts are located along the top outer edges of
the cabinet.
Daktronics strongly recommends using a spreader bar, or lifting bar, to lift the
display. Using a spreader bar ensures that the force on the eyebolts is straight up,
minimizing lifting stress.
