The screen of O
VER
V
IEW
D can be viewed at angles greater than 45 degrees without problems. The vertical view-
ing angle has been designed such that there is no difference whether the observer is standing or sitting.
In addition to the viewing angles, the room illumination should also be considered when installing O
VER
V
IEW
D.
Diffuse ambient light measured horizontally up to 300 lux and vertically up to 500 lux is no problem if the dis-
played image has a sufficiently high contrast.

Room ventilation
The room must be ventilated such that the room temperature is in the specified range. The electrical power con-
sumption of typically 210 W (cold standby) or 350 Watts (hot standby) per illumination unit 120W can be used as
a measure for the heat dissipation of O
VER
V
IEW
D into the room. (With illumination unit 100W, the respective
values are 190 W (cold standby) or 285 W (hot standby)
It is favorable to pass fresh and clean air through ventilation ducts in the floor below the structure. The inlets
should be provided with replaceable dust filters.
The electronic boards are very sensitive against being soiled with particles of e. g. carbon. Carbon dust is taken
up by the circuit boards thus causing short-circuits. When installing O
VER
V
IEW
D in critical environments like coal-
fired power stations etc. please make sure that there are no coal particles suspended in the air.
