IEC/EN 62368: A product may fall, causing serious personal injury or death. Many injuries, particularly to children, can be avoided
by taking simple precautions such as:
• ALWAYS use cabinets or stands or installation methods recommended by the manufacturer of the product set.
• ALWAYS use furniture that can safely support the product.
• ALWAYS ensure the product is not overhanging the edge of the supporting furniture.
• ALWAYS educate children about the dangers of climbing on furniture to reach the product or its controls.
• ALWAYS route cords and cables connected to your product so they cannot be tripped over, pulled or grabbed.
• NEVER place a product in an unstable location.
• NEVER place the product on tall furniture (for example, cupboards or bookcases) without anchoring both the furniture and the
product to a suitable support.
• NEVER place the product on cloth or other materials that may be located between the product and supporting furniture.
• NEVER place items that might tempt children to climb, such as toys and remote controls, on the top of the product or furniture
on which the product is placed.
If the existing product is going to be retained and relocated, the same considerations as above should be applied.

(B)
WARNING - THIS APPLIANCE MUST BE EARTHED.
Important:
This apparatus is supplied with an approved moulded 13A plug. To change a fuse in this
type of plug proceed as follows:+
1. Remove fuse cover and fuse.
2. Fit new fuse which should be a BS 1362 5A,A.S.T.A. or BSI approved type.
3. Retthefusecover.
Ifthettedplugisnotsuitableforyoursocketoutlets,itshouldbecutoandan
appropriate3-pinplugttedinitsplace.
If the mains plug contains a fuse, this should have a value of 5A. If a plug without a
fuse is used, the fuse at the distribution board should not be greater than 5A.
NOTE: The severed plug must be destroyed to avoid a possible shock hazard should it
be inserted into a 13A socket elsewhere.
How to connect a plug
The wires in the mains lead are coloured in accordance with the following code:
BLUE - “NEUTRAL” (“N”)
BROWN - “LIVE” (“L”)
GREEN & YELLOW - “EARTH” (“E”)
1. The GREEN & YELLOW wire must be connected to the terminal in the plug which is
marked with the letter “E” or by the Earth symbol or coloured GREEN or GREEN &
YELLOW.
2. The BLUE wire must be connected to the terminal which is marked with the letter “N”
or coloured BLACK.
3. The BROWN wire must be connected to the terminal which marked with the letter “L”
or coloured RED.
Before replacing the plug cover, make certain that the cord grip is clamped over the
sheath of the lead - not simply over the three wires.

5. Installation
Precautions when handling the cabinets:
• Do not drop or apply shock/vibration to the product. Strong impacts may damage the component inside.
• Onlyaqualiedservicetechnicianshouldperforminstallation.
• Only use approved cabinets.
• Be careful not to damage the corners of the cabinet.
• Install the display in a well-ventilated area.
• Always wear anti-static gloves when touching the display.
• Provide air conditioning around the LED display to allow heat dissipation away from the display.
• To maintain proper ventilation, keep clear space from the mounted displays to the wall. (Refer to the diagram below for the
recommended distance between the LED display and wall). Installing the product in poorly ventilated spaces may damage the
LED.
A wall mount kit (in some regions sold separately or available from third party vendors) allows you to mount the LED display on
the wall. For detailed information on installing the wall mount, see the instructions provided with the wall mount. Wall mounting
can only be performed from the front side of cabinets.

The mounting interface should be strong enough to bear the weight of the display. Ensure that your wall mount bracket has
the mounting holes accurately drilled at proper position.

Step 2.
Move up to install the next row. Install the connecting plates on the bracket. Rotate the hex key clockwise until the screw bolts
are inserted. Do not tighten the screw bolts yet, as this will cause unevenness of the connecting plates.

Step 3.
Align the cabinet with the connecting plate and secure the cabinet to the holes on the connecting plate. Rotate the hex key
clockwise until the screw bolts are inserted. Do not over tighten the screw bolts yet as you may need to adjust the connecting
plates again.
Step 4.
Tighten the screw bolts (
1
). Move up to install the next row. Install the connecting plates on the bracket. Rotate the hex key
clockwise until the screw bolts are inserted (

Step 5.
When mounting two cabinets one on top of the other, hold the cabinet at both side edges and slide it down vertically. If the
cabinet seems to be tilting to one side, adjust it until the display becomes level.
Step 6.
Align the second cabinet with the connecting plate and secure the cabinet to the holes on the connecting plate. Rotate the hex
key clockwise until the screw bolts are inserted. Do not over tighten the screw bolts yet as you may need to adjust the connecting
plates again.

Step 8. (for 180° angle installation)
For 180° angle installation, appropriate clearance between two cabinets must be considered. Follow the installation steps below.
Tighten the screw bolts (
1
). Repeat the above steps until all cabinets are mounted onto the bracket.
Use the feeler gauges to ensure accurate gap is reserved between the cascaded cabinets. Insert 2 pieces of 1mm feeler gauge into
the gap between two parts as illustrated below (
2
).
The feeler gauges are not provided with the product.
