A27 V3 Series Product User Manual
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
① The wiring should be neat, horizontal and vertical, and non cable cables
must be laid with wire slots or conduits;
②
The signal line and power line are laid separately to avoid interference;
③ The wiring should consider three-phase power balance, and try to have an
equal number of display panel es for each phase of electrical load;
④ The cable head needs to be pressed with wire terminals;
⑤
Encode the wire ends, and ensure that the overall distribution diagram is
consistent with the actual wiring for easy troubleshooting in the future;
⑥ Under 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;
⑦
Long distance wiring, considering line loss voltage, to ensure that the display
terminal voltage is within the allowable range;
