3.2 Installation environment requirements
1. The small spacing series requires on-site temperature and humidity testing to
ensure that the temperature is within 35 ℃and the humidity is within 70% RH;
2. When the temperature exceeds (35 ℃, 70% RH), the product cannot be
installed on site;
3.3 Precautions before installation
Before installation
1. Determine the power distribution plan:
Provide a specific power distribution plan based on the size and arrangement
order of the actual display screen, determine the specifications and quantity of
the power distribution panel , main power lines, and the number of power lines
connected to the cabinet. Determine the specifications and quantity of the
sending panel and video processor, as well as the number of network cables,
based on the total pixel points and arrangement order.
2. Power distribution precautions
①The wiring should be neat, horizontal and vertical, and non cable cables
must be laid with wire slots or conduits;
②The signal line and power line are laid separately to avoid interference;
③The wiring should consider three-phase power balance, and try to have an
equal number of display panel es for each phase of electrical load;
④The cable head needs to be pressed with wire terminals;
⑤Encode the wire ends, and ensure that the overall distribution diagram is
consistent with the actual wiring for easy troubleshooting in the future;
⑥Under the premise of considering the safe carrying capacity, lay the cables
from the distribution panel to the display screen panel based on the actual
arrangement of the panel;
⑦Long distance wiring, considering line loss voltage, to ensure that the display
terminal voltage is within the allowable range;

3. Tool preparation: commonly used tools for screen installation, including
matching and preparing models with tools such as screwdrivers, wrenches, and
multimeters.
During installation
4. Installation of distribution panel : The installation of distribution panel must
be firm and reliable. Reliable protective grounding.
5. Panel installation: equipment handling. Adequate manpower must be
provided to ensure safety. Pay attention to handling with care and avoid
damaging the appearance and function of the panel due to collision. Install the
display screen and check if the magnet legs are tightened. Confirm that the
power cord and network cable are connected in place and correctly, the
network cable is inserted in place, and the screen connection sequence is
correct.
6. Wiring sequence: First, connect the panel in series with a power cord
connected to the panel, and then connect the main power cord from the
distribution panel or socket to the bottom layer of the panel.
7. Power connection: Firstly, confirm that the power supply end is in a
"disconnected" state and must start connecting from the power consumption
end (equipment switch or distribution panel , etc.). Only after checking the
correct connection of the power supply end can the power supply end be
connected. First, connect the protective grounding, then connect the zero line,
and finally connect the phase line. After connecting to the power supply: Check
the power supply switch or equipment distribution voltage, confirm that there
are no errors, and then "disconnect" the power supply. The power cord must be
distinguished by color for ground wire, neutral wire, and phase wires such as A,
B, and C.
8. Panel adjustment: Check if the display screen is flat and clean. Perform
micro silicon adjustment on the gaps between modules and between panel es.
When installing, be sure to lock the panel tightly with screws to ensure the
smoothness of the left, right, top, and bottom between the panels.
9. Power test: Before supplying power to the entire screen and providing control
signals, please carefully check whether the power and signal lines are
connected correctly; Please carefully check the "L" line, "N" line, and "PE" line
on the AC power input port of each panel to ensure that there is no short circuit
between the three (measured with a multimeter).
10. Power on detection: Fault diagnosis, checking the appearance of the
power on detection for any broken screen and correct text output; If a fault
occurs, make a judgment based on the fault phenomenon and eliminate the

A27 V3 Series Product User Manual
17
fault.
4 Product Installation
4.1 Steel structure installation
Install layer by layer from bottom to top. First, lock the connecting screws
between the panels, and then use connecting plates and M8x55mm screws to
fix them on the square joint. Install M6x50mm "Z" axis adjustment screws on
the connecting plates.
After the installation of the panel is completed, confirm that the wires are
connected before installing the module on the panel according to its number.
