3.4.8 Installation with the screen downward

This display is designed to be installed with the screen downward, but certain uses can interfere with proper ventilation.
Please observe the following conditions:
1 Use plate metal that keeps all single holes clear and has dimensions no larger than those given in the following
table.
2 Leave adequate ventilation space between the display and the ceiling.
3 Use plate metal having sufficient strength (incorporating a safety factor of approximately four), and secure at the
four points indicated in the following drawing (four-point mounting). Mounting plate metal on a ceiling involves
certain hazards. Make sure you provide adequate back-up safety measures.
4 Recommended ambient operating temperatures are given in the following table. Operate the display within this
range of temperatures.
5 The ceiling should closely approximate a perfectly flat plane. Keep deformation pressures applied to the display,
such as twisting and bending, at or below 1 mm.
