5. Allowable temperature and installation
environment
When installing the display in a narrow place (in a case embedded in a wall, etc.), leave gaps as shown in the gure below
between the display and the wall to prevent an increase in the temperature.
You may also implement suitable cooling measures.
100 mm
100 mm
30 mm
100 mm
100 mm
40°C (104°F) or less
The guaranteed ambient temperature for the display is 40°C (104°F).
When using it inside a case, take measures such as installing cooling fans in the case or air vents to keep the temperature
inside the case at a temperature of 40°C (104°F) or lower.
The display is equipped with temperature sensors and cooling fans. These fans turn on automatically when the inner
temperature is too high.
A warning is displayed in any environment that exceeds the guaranteed temperature, even when the cooling fans are
being used.
Using the display in an environment where a warning is displayed may cause a malfunction. In such a case, turn o the
main power supply.
In addition to automatic operation of the built-in cooling fans when the temperature exceeds the guaranteed temperature,
you can set the cooling fans to operate continuously under DISPLAY PROTECTION → FAN CONTROL in the OSD menu.
When using the display with an option board, some of the cooling fans may turn on automatically to cool the option board
even when the display operates within the guaranteed temperature range.
When the display is installed inside a case or when it is used with the LCD surface covered with an acrylic sheet or other
protective sheets, check the inner temperature under DISPLAY PROTECTION → HEAT STATUS in the OSD menu and then
congure the fan operation as required.

6. Wall mount brackets installation
(1) Use only mounting brackets that comply with the VESA standards.
(2) Install the display only after thoroughly checking the strength of the mounting surface.
(3) Use mounting brackets strong enough to support the display.
(4) Check the strength and other safety factors before installing the display.
(5) Refer to the mounting brackets manual for details on the mounting method and on how to guarantee the
installation safety.
(6) When using M6 screws, make screw holes of 8.5 mm or less in diameter.
When using M8 screws, make screw holes of 10 mm or less in diameter.
(7) Pay attention not to leave any gap between the installation surface of the display and the mounting brackets.

(8) When installing the display on a wall or the ceiling, install a fall protection wire rope for safety.
(9) Never attach the display to a wall or the ceiling using only the fall protection wire rope.
(10) Install the fall protection wire rope not fully stretched.
When attaching the fall protection wire rope to the handles, use the handles shown in the picture below
depending on the orientation.
When attaching the fall protection wire rope to the speaker brackets, follow the method shown in the gure
below.

(12) The display fans are located at the three locations shown in the gure below.
Do not obstruct the fan vents with the mounting brackets or other parts.
There are 3 fan vents when the option board is used, and 2 fan vents when the option board is not used.
Using the display with the fan vents obstructed may cause a malfunction.

(13) When using the NEC wall mount kit, remove the upper cushioning materials and x the display top brackets to the
display using screws.

(14) It is possible to x the display bottom brackets by passing the screw through the holes in the lower cushioning
materials.
Since it is possible to x the brackets with the display maintained by the cushioning materials in the vertical
position, there is no risk to damage the screen.

7. Multiple screens installation
(1) When installing the displays in a multiple screens conguration, turn the displays o and leave a gap of 1.0 mm
between each display.
Note that light from the back may pass through the gaps between the displays.
To prevent the light from passing through the gaps, install a plate that stops the light at the back of the displays.
This plate is not supplied by NEC.
Gap of 1 mm
Gap of 1 mm
(2) Consider the following when installing the display in a multiple screens conguration.
(a) Check that the wall to which the mounting brackets will be installed is perfectly at.
(b) Make sure that the mounting brackets used are strong enough to meet the installation requirements.
(c) Choose a structure in which load is not applied on the display top and left sides.
(d) Pay attention that the cable route does not interfere with other parts of the structure.
(e) Choose a conguration with which there is no risk that the displays bend after they have been installed.

8. Pins, spacers and plastic spacers
Some display models are supplied with pins, spacers and plastic spacers.
With multiple screens conguration, installing the pins and the spacers makes it possible to secure a constant gap between
the displays.
However, the pins can be installed only on the models that have pin holes of 6 mm in diameter in their bottom and right
sides.
The pins cannot be used with the other models.
Also, the pins, spacers and plastic spacers cannot be used for installation brackets that allow the display to move (Example:
Pantograph mechanisms, slide mechanisms).

Front side
(1) Spacers
The spacers supplied with the display can be installed in the screw holes on the top and left sides of the display.
They are useful to prevent the display from coming into contact on their weaker sides with other displays in multiple
screens conguration. Therefore, we recommend installing these spacers in this conguration.
However, it cannot be used for installation brackets that allow the display to move back and forth or left and right
(Example: Pantograph mechanisms, slide mechanisms).

(2) Plastic spacers
Plastic spacers are useful to prevent the display from coming into contact on their weaker sides with other displays.
Remove the release paper from the back of the spacer double-sided tape, and stick the spacer to the edge at the
back of the display.
However, it cannot be used for installation brackets that allow the display to move (Example: Pantograph
mechanisms, slide mechanisms).

Example: Plastic spacer installation with multiple screens conguration
* Caution: When using movable installation brackets
• If pins are installed to the display, the display cannot be moved.
• If spacers or plastic spacers are installed to the display, the display may be rubbed or touched with spacers or plastic
spacers to cause abnormal images.
• When using movable brackets for installation, do not install pins, spaces and plastic spacers.
• Example of movable installation brackets are such as pantograph mechanisms, slide mechanisms.
