Daktronics CH-2024V - Manual (Page 8)

Installation 2-2
These footing recommendations are based on an allowable soil bearing pressure of 4000 psf
vertically and 400 psf/ft of depth horizontally. However, these recommendations are
suggestions only and each installation should be treated individually. Be sure that the
installation complies with local codes and is suitable for particular soil and wind conditions.
Daktronics assumes no responsibility for structures installed by others. Daktronics
recommends that W-sections of grade 36 steel be used for beams, and that 28-day (strength
4000 psi) concrete be used for footings.

Display Mounting
Reference Drawings: Display Mounting, CH-2024V ....................... Drawing A-46534
Drawing A-46534 shows the typical mounting procedure for the display.
Note: The bolts that secure the display do not go through the beams, but run along both sides
of the beams, clamping the display to the beams.
Mounting angles and 1/2" hardware are provided to mount your display.
1. Starting with the bottom display section, lift the display into place on the mounting
beams.
2. Secure the bottom of the lower display section as shown in Steps 1 through 4 in Drawing
A-46534.
3. Secure the top of the display section with the mounting angles and the 1/2" hardware.
4. Tighten all nuts securely.
5. Repeat the same procedure for the middle and upper sections, starting with the middle
section next.

Color Code, 25 Pin J-Box................ Drawing A-47207
For the display, two conductors of 24 AWG are needed. For distances up to 600 ft. or
22 AWG, up to 1000 ft. are required. Daktronics has 24 AWG direct burial cable,
Daktronics part no. W-1105 with 6 conductors, and 22 AWG cable that must be
pulled through the conduit before burial, Daktronics part no. W-1077 with 2
conductors.
At the control location, mount the signal J-box to a convenient location. Route the
cables and connect to the wires leading from the connector into the J-Box cover
according to the table below and Drawing A-47207.
At the display’s bottom section, open the bottom hinged panel covering the entrance
enclosure as shown in Drawing A-46539. Remove the cover from the entrance
enclosure. Refer to Drawing A-46545 for an illustration of the components inside
the enclosure. Signal and power cables are routed into the rear of the display. There
are two knockouts for the conduit connection in the back of the bottom section. Refer
