Special installation (Ceiling suspension (using wires))
3.4.4 Ceiling suspension (using wires)
When suspending the display by wires, use a combination of two mounting rows, as shown in the diagram above (rows
A - B or C - D, from rows A - D). This is done to safeguard against subjecting the display to twisting forces. Use a
minimum of four mounting points.
Use the following metal fixture to keep load from centering on the two mounting points at the top. As discussed in
3.4.1 Fixing on a struc, avoid blocking any ventilation holes other than those in the shaded ( ).
When attaching cables to the ceiling, install two cables at two independent points for safety.

If the display is
suspended close to a
wall, provide at least
300 mm clearance
between that wall
and the display.
Use mounting screws with minimum strength equal to that of mild steel cable, or stronger screws with hexagonal
socket heads.
The cable must be capable of supporting a load four times as heavy as the total weight of the display (30.8 kg
<31.6 kg>) plus the weight of the metal fixture, if one is used.
Provide auxiliary back-up cables to safeguard against breakage of main cables due to earthquakes etc..
