• Is anything missing from the delivery? Compare the scope of delivery with the information
you specified in the order.
3.1.2 Transportation and storage
Note the following points:
• Pack the device so that is protected against impact for storage and transportation. The
original packaging provides optimum protection.
• The permitted storage temperature range is –40 to +85 °C (–40 to +185 °F); it is possible to
store the device in the borderline temperature ranges for a limited period (maximum 48
hours).
3.2 Installation
NOTICE
Overheating due to heat accumulation in the device
‣To avoid heat accumulation, please always make sure the device is sufficiently cooled.
If the device is operated in the upper temperature limit range, this reduces the operating
life of the display.
The transmitter is designed to be used in a panel.
The orientation is determined by the readability of the display. Connections and outputs are
fitted on the rear of the device. The wires are connected by means of number-coded terminals.
Ambient temperature range:–10 to +60 °C (14 to 140 °F)
3.3 Dimensions
Observe the installation depth of 150 mm (5.91 ") for the device incl. terminals and fastening
clips.
More dimensions can be found in Section "Technical data" (→ 33).
• 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.
