Electrical Installation 3-2
3. Termination Panels & Termination Blocks:
Termination panels and termination blocks
connect internal power and signal wires to
wires of the same type coming into the display
from an external source. Most signal wire will
come with forked connectors crimped to the
ends of the wire. Power wires need to have
one-half inch of insulation striped from the end
of the wire prior to termination. Tighten all
screws firmly to ensure a good electrical
connection. Refer to Figure 23.
4. Phoenix -Style Connectors:
Phoenix-style connectors, which are usually green, terminate signal
on circuit boards. Refer to Figure 24. Strip one-quarter inch of
insulation from the wire prior to termination. To remove a wire, turn
the above screw counter-clockwise to loose the connectors grip on
the wire. To insert a wire, push the bare wire into the connector and
turn the above screw clockwise to lock the wire into place.
5. Mate-n-Lok Connectors:
The Mate-n-Lok connectors found in this display
are white and come in a variety of sizes. Figure
25 illustrates a four-pin Mate-n-Lok connector.
To remove the plug form the jack, squeeze the
plastics locking clasps of the side of the plug and
pull it from the jack.
6. Tab Connectors:
The tab connector, illustrated in Figure 26, is in
most Daktronics displays. Grab the connector on
the plastic terminal cover when removing. Do
NOT pull it off the tab by pulling on the wire.
3.2 Display Power Requirements
Reference Drawing:
Pwr Specs’s: 8, 16, 24, 32, 40, 48 ....................................................... Drawing A-103186
The table on Drawing A-103186 summarizes the power requirements for the various 1600 Series,
1.5-inch large matrix displays. It states power per display face.
3.3 Checking Line Voltage & 24-Hour Voltage Monitoring
Perform a two-part voltage check prior to display installation. This is a necessary step taken to
maximize lamp life. By looking-up the line voltage on the table in this sub-section, estimated lamp
life may be calculated and, if necessary, the user can take steps to extend it.
In Appendix B are two copies of the form, “Display Power Report.” Three different voltage readings
on this form are as follows.
