1�
Open the bottom-left panel of the lowest digit module of the display.
2�
Mount the power/signal plate in the left side of the lowest digit module of the display.
Remove both the 2" knockout and the upper 7/8" knockout from the left end of
the module. Route the power cord out of the module through the knockout and
position the plate inside, on the end. Secure the plate with two screws, inserting them
externally through the pre-drilled holes.
3�
Route the cable from the power/signal plate into the driver enclosure and connect
the 5-pin
J51
jack to the mating
P51
plug.
4�
Insert 2'' bushings into the holes between modules.
5�
Pull the power/signal cable from the lower module through the 2" hole in the top of
the cabinet up into the next module and connect the 5-pin
J51
jack to the mating
P51
plug in the driver enclosure.
6�
Repeat the connection process in
Step 5
with any other modules in the system.
7�
Connect the power cord to a 120 VAC power outlet.
8�
Replace the front panel. Insert a 2" plug in the bottom hole of the lowest module.
The hookup procedure for a 230 V display is identical; the only difference between the
two electrical systems is the power cord. Refer to
DWG-130676

Grounding
All components of a display system – including but not limited to displays, control
equipment, and connected peripheral equipment – must be electrically grounded.
Only qualified individuals may perform electrical work, including verification of ground
resistance. Daktronics is not responsible for improper grounding or damage incurred as a
result of improper grounding.
Grounding methods must meet the provisions of all applicable local and national codes.
Inspect and verify all grounding methods meet the provisions of all applicable local and
national codes.
Proper grounding is necessary for reliable equipment operation and general electrical
safety. Failure to properly ground the display system may void the warranty, disrupt
operation, damage equipment, and cause bodily harm or death.
There are two types of power installation: installation with ground and neutral conductors
provided, and installation with only a neutral conductor provided. These two power
installations differ slightly, as described in the following subsections:
Installation with Ground and Neutral Conductors Provided
For this type of installation, the power circuit must contain an isolated earth-ground
conductor. In this circumstance, do not connect neutral to ground at the disconnect or
at the display as this would violate electrical codes and void the warranty.
Use a disconnect so that all ungrounded lines can be disconnected. The local and
national electrical codes may require using a lockable power disconnect at or within
sight of the display.
