Daktronics TI-2002 Portable LED Timer - Manual (Page 11)

Electrical Installation 5
Mechanical Installation
Daktronics portable timers may simply be placed on a table, counter, or floor. Model 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 a
user‟s individual installation needs or provide mounting hardware suitable for every
installation. Mounting hardware may be purchased at a local hardware store. Choose a
method of installation that will safely support the weight of the display.
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 V AC 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
requires a 120 V AC receptacle and uses less than 1 A of power.
Displays operating on 230 V AC are also available, and they are shipped equipped with a
universal power plug.
Grounding
Connect the display to earth ground. Proper grounding assures reliable equipment operation
and protects the equipment against damaging electrical disturbances and lightning.
Daktronics recommends a resistance-to-ground of 10 ohms or less. The electrical contractor
performing the electrical installation can verify ground resistance. Daktronics Sales and
Service personnel can also provide this service.
Note: The customer must properly ground the outlet according to local and national
codes. Failure to ground the outlet voids the warranty for the display.
Signal Connection
Signal installation requires routing control cable from the control console to the display. At a
minimum, use a paired, 24 AWG shielded cable.
1. Insert one end of the signal cable into the SIGNAL IN (J31) jack located on the right
side of the display.
2. Connect the other end of the signal cable into the J1, J2, or J3 jack on the All Sport
5000 console or J1/J2 on the All Sport 1600 console.
