Daktronics C44 - Manual (Page 18)

2-4 New Track
Installation
Electrical
All electrical equipment used in the timing system runs on standard 120 Volts AC/60 Hz.
Noise (Radio/PA)
Important: The C-44 data cables must never be run with AC (power) or PA (Public
Address) cables. The data cables may cross AC or PA cables when absolutely
necessary but only at 90-degree angles. If it is necessary to run AC or PA cables
parallel to a data able, the cables must not be closer than 24".
In addition, care must be taken to insure that radio transmitters or television high
voltage transmitters are far enough from the track to prevent noise interference. If
these transmitters are close to the track, all cable must be shielded to prevent
interference.
Care must be used to insure that the cable not be crimped or bent into too tight a
radius. If it is necessary to put bends in conduit, they should be sweeping nineties.
Grounding
All equipment used with the timing system must be properly earth grounded. Make
sure all outlets and cords are three-conductor (grounded). All extension cords or
extra wiring must be three-conductor as well.
Important: Check to be sure that the service entrance (for the power) is properly
earth grounded. If it is not grounded, have it properly grounded.
Isolated Power Circuits
Daktronics recommends that the control equipment (i.e. C-44 console) be on a
dedicated power circuit to prevent noise interference. Air conditioners, fans, or high-
powered electrical equipment may cause noise interference or a brown-out which
would reset the system.
Electrical Code
The National Electrical Code and all local codes must be followed when installing
electrical equipment. It is the responsibility of the installer to see that this is done.
Equipment damage or personal injury can occur if these codes are not followed.

This section will explain how and where the track equipment should be mounted for a 1/8th
and 1/4th mile track. The distances for track setup are national standards and should be
followed.
