3 Display Installation
This section provides general guidelines for DB-65 display installation. Work closely with
the Project Manager on all installations. Do not modify the display or control system in
any manner without the written permission of the Project Manager. Any unauthorized
modications may void the display warranty.
Display Installation
1� Using a utility knife, carefully cut away all of the white packaging material from the
display. Pay special attention when cutting around the Multi-Direction Light Sensor
(MDLS) to avoid cutting cables. If possible, do not cut anywhere along the display
face as it can damage the LEDs and modules.
2� Remove the wood and the wood braces from the top of every display section.
3� Locate the spare parts rack in the bottom-left end bay (when viewed from the back)
and verify all installation tools and installation hardware were sent with the display.
Contact the Project Manager immediately if missing installation parts.
4� Verify that the lift-eyes are installed and the lift-eye bolts and set bolts are in place.
Refer to Figure 3. Lift eye spacing is set at Daktronics and should not be moved
without the Project Manager’s permission.
5� The angle on the lift-eye straps must be greater than 55° from horizontal. If there
are more than 2 lift-eyes, attach a spreader beam. Each lift-eye must have its own
strap. Refer to Figure 3. The table shows Daktronics recommended strap lengths for
common display sizes.

17� After hanging the display, connecting display power, and starting the display, call
Daktronics NOC and have a technician verify they can detect the video server. If
the video server is not detected, ensure the power and signal cables are securely
attached to the camera and display. Make sure the video server has power and is
connected with Cat-5e cable to the network switch on the router.
18� Work with the NOC to ensure the camera is aligned properly.

7 Electrical Installation
This section provides general guidelines for connecting power to a 65 series Daktronics
digital billboard. For display-specic power requirements, refer to the riser diagram or
contact the Project Manager.
Note: Provide the site-required power to the display as listed on the system riser drawing.
Low or poor power can result in dim content, parts of the display out, module
ickering, or display damage.
Main Disconnect
Daktronics requires using a power disconnect switch with the display. Use a disconnect
so that all ungrounded conductors can be disconnected near the point of power
connection.
Locate the disconnecting means either in a direct line of sight from the display or so it
can be locked in the open position. This ensures that power is not reconnected while
service personnel work on the display.
Electrical Installation
1� Refer to the display riser diagram for site-
required power.
2� Run conduit from the main distribution panel
(provided by customer) to the display power
entrance(s).
3� Route power to the display through a
disconnect switch.
4� Loosen the four screws that secure the power
entrance cover and lift it off of the power
entrance. Refer to Figure 28.
5� Feed power cable through the conduit into the
power entrance.
6� Connect the ground wire to the ground lug on the left
side in the power entrance box (green wire) and
tighten to 45 in-lbs with a 3/16″ hex head wrench. Refer
to Figure 29.
7� Connect power line 1 (L1) to Line 1 of the tap and use
a 3/16″ hex head wrench to tighten to 57 in-lbs.
8� Connect power line 2 (L2) to Line 2 of the tap
and use a 3/16″ Hex head wrench to tighten to
57 in-lbs, as shown in Figure 30.
9� Connect the neutral line to the neutral tap
and use a 3/16″ Hex head wrench to tighten to
57 in-lbs.
10� Verify the breakers for the control equipment
and surge suppressor are on.
