Product care
• All parts must be fully protected and packed in good order during transportation, storage,
etc. No external pressure shall be applied on them.
• No part of the product can come into contact with rain before or during installation. Keep
them in dry and clean places.
• All parts must be prevented from being trampled, stroke or dropped. Follow all
instructions while carrying or moving the parts. Otherwise the product can be subject to
terminal damage.
Installation
• Before installation, ensure that the supporting structure or frame has sufficient strength
to hold the LED video wall firm and safe.
• For hoist installation, the operator must follow all instructions given in this User's Manual,
including where the hoist brackets should be located, that the crane used must come with
sufficient capability to hoist the product, and that the operating ground must have the
strength to sustain the crane, etc.
• Most components of the product are heavy. Therefore high attention should be paid to
personnel safety during installation.
• All connection bolts must be fastened firmly and securely.
Power
• The LED video wall is to be powered by a 3-phase power with 4 lines. That is, it must come
with an independent neutral line and an independent ground line.
• Provide the power and power supply circuits in accordance with the power consumption
of the LED video wall. All circuits must come with protection tubes and confirm with the local
electrical safety standards.
• The LDU and PSU must be installed near the LED video wall. Cables from the LDU and PSU
to the LED video wall cannot be stretched or impaired. Power distribution from the PSU to
the LED video wall cannot exceed what is required by this User's Manual.
• The input voltage of an the LED video wall can be set from 120VAC or 220VAC. But ensure
to set it right before power connection.
• Do not attempt to fix an impaired cable. Replace it with a new one.
• A big current is produced the moment a LED video wall is powered on. Therefore an air
breaker that can sustain big currents should be used as the master power switch.
Grounding
• The LED video walls must be grounded with an INDEPENDENT ground wire.
• LED video walls to be installed independently from any architectural structure must be
equipped with an independent ground wire and, if necessary, a lightning rod. The down lead
of the lightning rod should be insulated with the frame of the LED video wall. Set the earth
electrode of the lightning rod and that of the ground wire away from each other.
