3 Installation
3.1 Incoming acceptance, transport, storage
The permitted ambient and storage conditions must be observed. The precise specifications can
be found in Section "Technical data" (® ä 35).
3.1.1 Incoming acceptance
On receipt of the goods, check the following points:
• Are the packaging or contents damaged?
• 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" (® ä 35).
• 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.

3. To secure the tube in the panel, hold the device in a horizontal position and push the
installation frame (item 1), with the threaded rods screwed in, over the tube until the frame
locks into position.
4. Tighten the threaded rods to fasten the device in place.
To disassemble the device, the mounting frame can be unlocked at the locking elements (item
5) and then removed.
3.5 Post-installation check
• Is the sealing ring undamaged?
• Is the mounting frame securely engaged on the housing of the device?
