Data Distributor Electrical Installation
If the display has a data distributor, follow these steps to complete power, signal and internal
temperature monitoring system connections. For a description of the difference between a display
with a line receiver and a data distributor refer to Section 1.3.
Connecting Power to the Data Distributor
Whenever possible, Daktronics runs power from the display or section panelboard to the data
distributor prior to shipment. However, certain situations may require running this power in the
field.
Power should run in conduit to the base of the data distributor enclosure. On the bottom of the
enclosure are knockouts for conduit attachment. Conduit and labor to pull the power cable is the
responsibility of the customer or contractor unless otherwise stated.
Having removed the front cover of the data distributor, pull the power cable to the power
termination block in the upper-left hand corner of the enclosure. Figure 30 illustrates the upper-
left hand corner of the data distributor.
This termination block has a protective plate; remove this plate to connect the hot, neutral and
ground wires. Strip and connect the incoming wires in agreement with the labels beside the
termination block.
