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 / Compass

• 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.

Note: for accurate compass readings, an aluminium mast is recommended.

7.3.3 Sensors with Radar Precipitation Measurement

• Installation on the top of the mast

• Installation height at least 4.5m above the ground (if there are no moving objects in wider

circumference of the sensor, a lower installation height may be considered)

• Distance to road carriageway at least 1m

• Distance from moving objects (e.g. trees, bushes and even bridges) at least 5m at the

height of the sensor

• Minimum distance between devices with radar precipitation measurement: 8m.

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. Installation

locations where wind turbulence is to be expected, e.g. caused by buildings, should be

avoided.
