2 Mechanical & Electrical Installation
Mechanical Installation
Daktronics portable TI-2002 timers may simply be placed on a table, counter, or floor.
The TI-2002 also has a handle for easy transport as well as two keyholes on the rear of the
display for hanging on a wall.
Due to the variety of wall materials used in sports facilities, Daktronics cannot anticipate
every user’s individual installation needs or provide mounting hardware suitable for every
installation. Choose a method of installation that will safely support the display’s weight.
Note: Do not use the carrying handle to permanently suspend the display.
Electrical Installation
CAUTION: Only qualified individuals should access the electrical components of the
display and its associated equipment. It is the responsibility of the electrical contractor to
ensure that all electrical work meets or exceeds local and national codes.
Daktronics engineering staff must approve all changes or the warranty will be void.
Power
The display features a 120 VAC power cord with a three-prong plug. Install a grounded
receptacle near the equipment so that the power cord can easily reach it. The control
console also requires a 120 VAC receptacle. Like the display, the Daktronics controllers
use less than 1 Amp of power.
Displays operating on 240 VAC are also available, and they are shipped with a universal
power plug.
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.
Signal
Signal installation requires routing paired, shielded cable, 22 AWG minimum, between
the display location and the control location. Daktronics offers various lengths of control
cable; refer to Replacement Parts (p�8) .
1� Insert one end of the signal cable into the 1/4" phone J31 SIGNAL IN jack located on
the right side of the display.
2� Connect the other end of the signal cable into the 1/4" phone J1 , J2 , or J3 jack on
the All Sport 5000 console (or J1/J2 on the All Sport 1600 console).
