installation location.

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 VESA­compatible (FDMlv1) mounting method.

• NEC strongly recommends
using size M6 screws
(10mm + thickness of
bracket in length). If using
screws longer than 10mm,
check the depth of the hole.
(Recommended Fasten
Force: 470 - 635N•cm)
NEC recommends mounting
interfaces that comply with
UL1678 standard in North
America.

• 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.

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 (10cm) 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
