7.3 Selecting the Installation Location
In order to guarantee long service life and correct equipment operation, please pay attention
to the following points when selecting the installation location.
7.3.1 General Instructions
 Stable subsurface for installing the mast
 Free access to the equipment for maintenance works
 Reliable power supply for permanent operation
 Good network coverage when transmitting over a mobile communications network
Note: The computed measurements specifically apply to the equipment location only. No
conclusions can be drawn with regard to the wider environment or a complete road section.
ATTENTION:
 Only approved and tested appliances (conductors, risers etc.) should be used to install the
device on the mast.
 All relevant regulations for working at this height must be observed.
 The mast must be sized and anchored appropriately.
 The mast must be earthed in accordance with regulations.
 The corresponding safety regulations for working at road side and in the vicinity of the
road carriageway must be observed.
If the equipment is installed incorrectly
 It may not function.
 It may be permanently damaged.
 Danger of injury may exist if the equipment is allowed to fall.
7.3.2 Sensors with Wind Measurement
 Installation at the top of the mast
 Installation height at least 2m above the ground
 Free field around the sensor
Note: Buildings, bridges, embankments and trees may corrupt the wind measurement.
Equally, passing traffic may cause gusts which may influence the wind measurement.
7.3.3 Sensors with Precipitation Measurement
 Installation on the top of the mast
 Installation height at least 4.5m above the ground
 Distance to road carriageway at least 10m
 Distance from moving objects (e.g. trees, bushes and even bridges) at least 10m at the
height of the sensor
Note: Falling or moving objects, e.g. falling leaves or leaves blowing in the wind, may cause
false measurements and/or precipitation types.
Note: Strong wind can influence the accuracy of the precipitation measurement.
Note: When selecting the installation location please take care to position the device at a
suitable distance from other systems incorporating a 24GHz radar sensor, such as traffic
counting devices on overhead gantry signs. Otherwise cross effects and system
malfunctions may occur. In the final analysis, the distance to other measuring systems also
depends on their range of coverage and signal strength.
