A27 V3 Series Product User Manual
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
