6.5 Install Overframes and Power bar cover
The Overframes protect the LED Wall from any dust or other particles that could come in through
the holes on the sides and the top.
Inside the Overframes are slot nuts. The Overframes are attached to the LED Wall via screws,
which go through the Cabinet interlock anchors into the slot nuts.
Info
It is easier to install the Overframes first and later the Pixel cards. However, if the Pixel cards
are already installed, only a few Pixel cards need to be taken out to install the Overframes. The
pictures also show the procedure with installed Pixel cards.
This section is a guide through the assembly of the frame and its installation on the LED Wall.
