Daktronics Galaxy AF-3400 34 mm Monochrome/RGB - Manual (Page 17)

Section 3: Power Installation
Read the Mechanical, Power and Signal Installation sections
before installing the display(s).
Only a qualified individual should terminate power and signal cable at this Daktronics
display.
All proposed changes must be approved by Daktronics engineering staff or the warranty will
be rendered null and void.
3.1 Conduit
Daktronics does not include the conduit. Separate conduit must be used to route:
• power
• signal IN wires to the signal termination enclosure, when applicable
• signal OUT wires (if not using the provided interconnect cable)
The power J-box is provided with 3/4” threaded holes for use with 3/4” conduit.
Unthreaded 1/2" knockout holes are provided in the signal enclosures used with the display.
If not using the provided enclosures, use the knockout/ drill holes provided in the display
cabinet.
3.2 Overview of Power/ Signal Connection
Following is a brief summary of the power and signal connections to the display.
1. Enclosures are provided with the display for termination of both signal and power.
If the installation of the display does not allow for the use of these enclosures, refer to
Section 3.5 for diagrams on internal wiring for the power.
2. Possible methods for signal termination are shown in the manual for the specific
communication type.
3. Route power to the display through a fused disconnect switch capable of opening all
ungrounded power conductors. Install this disconnect within the line-of-sight of any
personnel performing maintenance on the display. If the disconnect is located out of
sight of the display, it must be capable of being locked in the open position.
Note for 1 and 2 circuit power termination panels: Displays are equipped with
supplemental protection devices that carry a UL1077 (IEC 60947, VDE 660) rating. These
devices are only intended to protect the components within the display. Suitable devices
must be used for the equipment and feeders supplying power to the display.
4. Power conductors from the disconnect to the display should be routed through
conduit in agreement with local code.
5. Display power will terminate at the power termination panel, either through the J-
box or directly. If the display has two faces, power will need to be connected to both
the primary and the mirror displays separately.
