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.
Drawing A-177150 provides instructions for power and signal connections for the
DataMaster Rate Displays, including hookup of the connections between host and
client displays. Refer to this drawing before undertaking any part of the electrical
installation.
3.2 Power and Ground Connections
Correct power and grounding installation is imperative for proper display operation.

to personnel.
Power
Daktronics DataMaster displays have been designed for easy access to components,
and the power and control signal hookup has been simplified. Front panels are
hinged to allow access to the digits, cabling, and other electronic components.
The DataMaster Rate Displays require a dedicated, 120 V circuit for incoming
power. The display itself has no breakers or fuses.
