The LS-4.6 is intended for indoor, professional use only. It is not suitable outdoor use or household use.
• Ensure that the power supply units are electrically connected to earth (ground).
• Do not immerse the device in water or liquid.
• Install only in accordance with applicable building codes.
WARNING! Read the safety precautions in this section before
unpacking, installing, powering or operating this product.

Introduction
The LS-4.6 is an ultra hi-res video panel capable of displaying detailed video from a high-resolution digital video source.
The panel is made up of LED modules with 3-in-1 SMD LEDs, making it suitable for applications where both picture quality
and brightness are important. The panel offers high light output of 900 cd/m2, and a contrast ratio of 1 600:1.
With 4.6 mm pixel pitch, the panel gives the best picture resolution and quality at a viewing distance of 4 meters or more.
With a high refresh rate of 2 880 Hz, it is perfect for applications such as television, theatre, exhibitions, show production
and concerts. The screen has no fans, making it completely noiseless.
The long-life LED system and very low pixel failure rate makes the LS-4.6 very suitable for permanent installations. At the
same time, the 8.5 kg low weight easy-to-assemble panels also provide a very attractive system for touring and rental
use. The modular panels can be quickly combined to create large suspended viewing screens. The panel is IP43-rated
and is designed for indoor installation.
This manual covers installation, use and maintenance of the LED Panel. For information about installation and use of the
LED Controller, see the documentation supplied with the controller. All documentation is also available from the SGM website: http://www.sgmlight.com.

Preparing for installation
Transportation
To protect the panels from shocks that normally occur during transport, they should be packed in an SGM flight case. The
product warranty does not cover damage from due to incorrect packing.
Unpacking
To avoid damage to the panels, it is recommended to leave the panels in the flight case until needed. Lift the panels one
at a time from the flight case, using the handle on the back of the panel.
• The LEDs on the panel are fragile. Avoid exposing front and edges of
the panels to shocks.
CAUTION Risk of damage to equipment.

Before use
If the LED panel has been unused for over 3 days, it must be preheated before using it at normal (80% to 100%) brightness
in order to avoid damage from moisture condensation in the panel.
Unused for: Preheat at 30% to 50% brightness for:
3 to 7 days 4 to 8 hours
over 7 days 12 hours

Installation
• The LEDs on the panel are fragile. Avoid exposing front and edges of
the panels to shocks.
• To avoid personal injury and damage to the panels, assembly must be
performed by two persons.
WARNING! Risk of injury or damage to equipment.
Manual_LS-4.6_V0_UK_170x113,3.book Page 14 Saturday, January 11, 2014 7:13 PM

• Do not suspend more than 15 panels in each vertical column.
• When suspending more than 2 panels, a hanging boom must be used
between every second unit.

Physical rigging
1 Start the rigging process by blocking the work area below and make sure the work is performed from a stable plat-
form.
2 Attach the short rigging booms with the half couplers to the rigging structure.
3 Attach a row of long rigging booms to the short rigging booms.
4 Lift the first LED panel into place (for example in the top left corner) between the mounts in the rigging booms.
5 Fasten the panel to the rigging using the 4 bolts.
When assembling a LED screen installation, mount the panels on the rigging booms one
by one. Mount one row of panels at a time starting from the top and working downwards.

8 Fasten the panel to the rigging using the 4 bolts.
9 Repeat steps 6 to 8 to complete a full row of panels.
6 Lift an LED panel (2) into position besides the previous panel (1).
(Make sure the latches are in the open position.)
7 Carefully align the panels (left to right) and lock them in place by turning the
2 latches with and Allen wrench.

12 Fasten the panel to the rigging using the 4 bolts.
13 Repeat steps 6 to 8 to complete a full row of panels.
14 Attach a row of long rigging booms to the short rigging booms.
15 Repeat steps 10 to 13 for the rest of the rows of panels.
10 Lift an LED panel (4) into place below the first panel (1).
(Make sure the latches are in the open position.)

Signal connection
The pixel data signal is passed from the LED controller to the LED screen through the signal cable. The individual LED
panels of the screen are connected in a daisy chain pattern. The LED controller must be configured to reflect the physical
connection pattern. (See LED controller documentation for details.)
The signal indicator (green) on the back of the panel flashes quickly (approx. every second) when a correct signal connection is established. When no signal is detected, the indicator flashes slowly (approx. every 5 seconds).
It is highly recommended to use the same connection pattern for connect both signal and power. The following figure
shows an example of the recommended signal connection pattern.
Manual_LS-4.6_V0_UK_170x113,3.book Page 19 Saturday, January 11, 2014 7:13 PM

Power connection
Power is supplied to the LED panels with power link cables. Power can be passed through the panels of the screen in a
daisy chain pattern. The power indicator (red) on the back of the panel is on when power connection is established.
It is highly recommended to use the same connection pattern for connect both signal and power. The following figure
shows an example of the recommended signal connection pattern.
• Do not connect more than 15 LED panels to a single line of power.
DANGER! Risk of fire.

Dismantling and storage
Dismantling
When dismantling a LED screen installation, remove the panels from the rigging booms one by one. Remove one row of
panels at a time starting from the bottom and working upwards. As panels are removed from the vertical rigging booms,
remove the free rigging booms.
• The LEDs on the panel are fragile. Avoid exposing front and edges of
the panels to shocks.
• To avoid personal injury and damage to the panels, assembly must be
performed by two persons.
WARNING! Risk of injury or damage to equipment.

22
Storage
When not in use, it is recommended to store the LED panels in the flight case. Using the handle on the back of the panel,
carefully slide the panel down into an open slot in the flight case.
The LED panel must be stored in the environment with temperature less than 30°C (86°F) and humidity less than 60%.
