This manual provides installation, maintenance and troubleshooting information to help ensure the optimal
performance of the Daktronics Galaxy® AF-3220 series display. Diagnostic and parts replacement information are also
included. The back and side views of a typical display are shown in Figure 1.

1.1 Display Details
Galaxy® model numbers are described as follows:
AF-3220-RRxCCC-34-R, A, RGB-XX
AF-3220 = Outdoor Galaxy display
3220 = Series Number of Display
RR = Number of pixel rows high (16 or 24)
CCC = Number of pixel columns long (up to 96 standard
34 = Pixel pitch in millimeters
R, A, RGB =
XX = SF (Primary) or 2V (Primary/Mirror)
LED Color: R (Red), A (Amber), RGB (Full Color
– Red, Green, Blue)
The displays are offered as SF (single-face) or 2V (two-view) units. With a 2V (two-view) unit, the first display
is called the primary and the second display is referred to as the mirror. If the second display will be mounted
at a distance of more than 6 feet from the primary display, then two primary displays must be used.
A typical display system is controlled with a Windows®-based personal computer (PC) running Venus® 1500
software.
Introduction 1
Section 2: Mechanical Installation
Daktronics’ engineering staff must approve any changes that may affect the weather-tightness of the display. If
any modifications are made, detailed drawings of the changes must be submitted to Daktronics for evaluation and
approval, or the warranty may be void.
2.1 Installation Guidelines
DO:
• Inspect the display for damage caused by shipping or uncrating
• Use all lift eyes when lifting the display maintaining 90 degrees between cabinet and lifting method
• Use all clip angles or bolt locations for mounting
• Leave adequate clearance for ventilation
• Ensure mounting location allows for door to pivot open
• Provide an adequate support structure that is straight and level
DON’T:
• Drill holes into the cabinet
• Modify the display without written approval from Daktronics Engineering
• Block intake vents on the bottom of the display
• Block exhaust hoods on back of display
• Use the lift eyes for permanent mounting
2.2 Support Structure Requirements
Daktronics is not responsible for installations or the structural integrity of support structures done by
others. The customer must ensure that a qualified structural engineer approves the mounting structure and
hardware.
Because every installation site is unique, no single procedure is approved by Daktronics for mounting
Galaxy® displays. The information contained in this section is general information only and may or may not
be appropriate for this particular installation.

The installer must ensure the
installation adequately meets local
codes and standards, including
safe, adequate mounting hardware
and procedures.
Note: To maintain the structural
integrity of the display cabinet,
a 90-degree angle between the
cabinet and the lifting method must be maintained.
1. Lift the display into position on the support structure following the
guidelines in Figure 2.
Be sure the mounting location leaves adequate space to pivot the
door open, as shown in Figure 9.
Do not attempt to permanently support the display by the eyebolts.
2. Weld or use ½" Grade-5 bolts and hardware to secure ALL clip
angles, as shown in Figure 3, to the support structure as shown in
the Shop Drawing.
3. Refer to Section 4 and the appropriate communication manual for
information on routing power and signal to the display.
Figure 2: Correct/Incorrect Lifting Procedures
4. After installation is complete, carefully inspect the display for any
holes that may allow water to seep into the display and seal any
Figure 3: Clip Angle
openings with silicone.
Note: If the eyebolts on the top of the display were removed, seal the holes with bolts and/or silicone.
4 Mechanical Installation
Section 3: Power Installation
3.1 Installation Guidelines
DO:
• Route power to the display through a fused disconnect switch
• Route power conductors through conduit according to local codes
• Install an earth-ground electrode for each display face – if resistance to ground is greater than 10 ohms,
install additional grounding electrodes
• Follow local and national electrical codes
• Provide a main power disconnect for the displays
DON’T:
• Connect the display to any voltage other than that listed on the product label
• Share a circuit or neutral with any other electrical devices such as light ballasts, parking lights, etc.
• Connect the neutral to the ground at the disconnect or the display
• Use the display support structure as an earth-ground electrode
3.2 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.
3.3 Power Requirements
Important Note:
• Daktronics recommends that a separate circuit be run to the electronic display(s) to isolate it and
prevent any issues that could be caused by line voltage fluctuations or high frequency noise on the
power line caused by other types of equipment. A separate circuit also makes display maintenance and
troubleshooting easier. Daktronics assumes no liability for any issues caused by line voltage fluctuations
or other improper power conditions if these recommendations are not followed.
• Size conductors of circuits that deliver power to a Daktronics display according to local and national
electrical codes so that the power distribution system delivers full-load power to the display while
maintaining a voltage within five percent (5%) of the nominal voltage.
Power Installation 5
• Displays use single-phase power. Proper power installation is imperative for display operation.
Main Disconnect
Daktronics requires using a power disconnect switch with the display. Use a disconnect so that all
ungrounded conductors can be disconnected near the point of power connection.
The disconnecting means must be located either in a direct line of sight from the display or can be locked
in the open position. This ensures that power will not be reconnected while service personnel work on the
display.
3.4 Grounding
Install this sign according national and applicable local codes. This includes proper grounding and bonding
of the sign.
Installation with Ground and Neutral
Conductors Provided
• These displays are installed
with ground and neutral
conductors provided. The
power cable must contain
an isolated earth-ground
conductor.
• Do not connect neutral to
ground at the disconnect or
at the display. This violates
electrical codes and voids the
warranty.

earth-ground electrode;
concrete, primer, corrosion, and other factors make the support structure a poor ground.
Note: The support structure may be used as an earth-ground electrode only if designed to do so. A qualified
inspector must approve the support structure and grounding methods.
The display system must be connected to an earth ground as shown in Figure 4. Proper grounding protects
the equipment from damaging electrical disturbances and lightning. Daktronics requires a resistance to
ground of 10 ohms or less. The display must be properly grounded or the warranty will be void.
6 Power Installation
3.5 Power Connection
1. Route the power cable through conduit to the rear of the
display and into the power J-box.
2. The power J-box contains two wires plus a ground
coming from the interior of the display. These wires are
pre-terminated to the power termination panel inside the
display.
3. Inside the external power J-box, connect the power wires
to the wires coming from the display interior using wire
nuts. Refer to Figure 5 for a diagram.
Note: The following colors are used for the pre-terminated
wires:
• Line 1 – Black (Brown – 240V)
• Neutral - White (Blue – 240)
• Grounding Conductor – (Green-Yellow)
