4．Product Cabling
Preparation before cabling
Before applying power and signal source to the screen, please check power and data
cables connections carefully and make sure they are wired correctly. Use a multimeter to
test the L, N and PE lines in AC power input port and make sure the three lines are not
short-circuited.
Power cord connection instructions: Please calculate and select the appropriate model of
distribution box or socket according to the maximum power consumption. Please consult
your electrician or distribution cabinet manufacturer for specific selection scheme. The
input voltage of the cabinet is 100-240V/AC. The 3X1.5mm2/16awg power cable is used
from the distribution box to the cabinet. Please confirm the input voltage, The number of
cabinets loaded on each power cable will be different upon different voltages and product
models. (Please feel free to contact our after-sales service department if you cannot
confirm).

A27 Plus Series User Manual - 18 -
Taking a [4x4] A2715 Plus screen for example, data and power wiring schematics are
shown below:
4.1 Power Supply Wiring
When the input voltage is 220V, each power cable can carry up to 14 cabinets. When the
input voltage is 110V, each power cable can carry up to 7 cabinets. The 16 cabinets of
A2715 Plus are loaded with two main power cables, and each main power cable carries
2*4=8 cabinets. First, the cabinets are connected with power cables of connecting
cabinets, and then connect the distribution box or socket to the bottom of cabinet with 3 x
1.5mm2/16awg power cables.
4.2 Signal Cable Wiring
4.2.1 Signal cable connection of standard product version
The signal cable of standard version uses RJ45 CAT5 network cable, and the network
cable interface of the cabinet can be used for input and output. For the "S" type of up-
down connection, please calculate the resolution according to the pixels of each cabinet
and connect the signal cables according to the loading range of the sending card.
Note: The range of loaded pixels of each net port cannot exceed 655360 points (as
shown in the following figure)
