3.1 Installation conditions
NOTICE
Overheating due to buildup of heat in the device
‣To avoid heat buildup, please always ensure that the device is sufficiently cooled.
Operating the display in the upper temperature limit range decreases the operating life
of the display.
The transmitter is designed for use in a panel.
The orientation is determined by the readability of the display. The connections and outputs
are provided on the rear. The cables are connected via coded terminals.
Ambient temperature range: –10 to +60 °C (14 to 140 °F)
3.2 Dimensions
Observe the installation depth of 150 mm (5.91 ") for the device incl. terminals and fastening
clips.
More dimensions can be found in the "Technical data" section →  31.
• Panel cutout: 92 mm x 45 mm (3.62 in x 1.77 in).
• Panel thickness: max. 26 mm (1 in).
• Max. viewing angle range: 45° to the left and right from the central display axis.
• If the devices are arranged horizontally beside one another in the X-direction, or arranged
vertically on top of one another in the Y-direction, the mechanical distance (specified by the
housing and front section) must be observed.
