1 Mounting Requirements
1.1 Bearing
You can choose the potable or wall mounting method according to your needs. Wall
mounting can substantially save the space.
If you choose portable mounting, use the mounting rack or support. If you want to use a
self-made mounting rack, the bearing capacity of the rack should be at last four times of
the actual weight of the display. The bearing capacity of the mounting support must be at
least four times of the actual weight of the display to ensure steadiness of the interactive
panel.
When you choose wall mounting, the bearing capacity of the mounting surface must be at
least four times of the weight of the display. When the mounting surface is a wall or
ceiling of a building, the wall must be built with solid bricks, concrete or materials of
equal intensity. If you need to mount the display on a loose surface such as an old brick
wall, wood plank wall, solid brick wall, metal or non-metal structure wall, or a wall with a
thick decoration layer, take necessary consolidating measures to ensure that the display is
steadily mounted.
1.2 Ventilation
