Please note the following when mounting
on wall or ceiling
• When using mounting accessories other than those that
are NEC approved, they must comply with the VESA-
compatible (FDMlv1) mounting method.
• NEC recommends mounting interfaces that comply with
UL1678 standard in North America.
• X464UN/X464UNS/X464UNV:
NEC strongly recommends
using size M6 screws
(10-12 mm + thickness
of bracket and washer in
length). If using screws
10-12 mm (X464UN/X464UNS/X464UNV)
longer than 10-12 mm,
10-14 mm (X554UN/X554UNS/X554UNV)
check the depth of the hole.
(Recommended Fasten Force:
470 - 635N•cm). Bracket hole should be under φ 8.5 mm.
• X554UN/X554UNS/X554UNV: NEC strongly recommends
using size M6 screws (10-14 mm + thickness of bracket
and washer in length). If using screws longer than
10-14 mm, check the depth of the hole. (Recommended
Fasten Force: 470 - 635N•cm). Bracket hole should be
under φ 8.5 mm.
• Prior to mounting, inspect the installation location to
insure that it is strong enough to support the weight of the
unit so that the unit will be safe from harm.
• Refer to the instructions included with the mounting
equipment for detailed information.
• Make sure there is no gap between the monitor and the
bracket.
• When used in a video wall confi guration for a longer
time, slight expansion of the displays may happen due to
temperature changes. Due to this it is recommended that
over one millimeter gap is kept between adjacent display
edges.

Orientation
• When using the display in the portrait position, the
monitor should be rotated clockwise so that the left side
is moved to the top, right side is moved to the bottom.
This will allow for proper ventilation and will extend the
lifetime of the monitor. Improper ventilation may shorten
the lifetime of the monitor.
Mounting location
• The ceiling and wall must be strong enough to support the
monitor and mounting accessories.
• DO NOT install in locations where a door or gate can hit
the unit.
• DO NOT install in areas where the unit will be subjected
to strong vibrations and dust.
• DO NOT install near where the main power supply enters
the building.
• Do not install in where people can easily grab and hang
onto the unit or the mounting apparatus.
• When mounting in a recessed area, as in a wall, leave at
least 4 inches (100 mm) of space between the monitor
and the wall for proper ventilation.
• Allow adequate ventilation or provide air conditioning
around the monitor, so that heat can properly dissipate
away from the unit and mounting apparatus.
Mounting on ceiling
• Ensure that the ceiling is sturdy enough to support the
weight of the unit and the mounting apparatus over time,
against earthquakes, unexpected vibrations, and other
external forces.
• Be sure the unit is mounted to a solid structure within
the ceiling, such as a support beam. Secure the monitor
using bolts, spring lock washers, washer and nut.
• DO NOT mount to areas that have no supporting internal
structure. DO NOT use wood screws or anchor screws for
mounting. DO NOT mount the unit to trim or to hanging
fi xtures.
Maintenance
• Periodically check for loose screws, gaps, distortions,
or other problems that may occur with the mounting
apparatus. If a problem is detected, please refer to
qualifi ed personnel for service.
• Regularly check the mounting location for signs of
damage or weakness that may occur over time.
