should be mount with a distance of at least 1m on the same mast. The side distance to other
objects should be greater than 2m.
We recommend to operate the Laser Precipitation Monitor in an enclosed area for human safety,
although the intensity of the invisible laser beam is considered as safe for the human eye (without
using optical instruments, Laser Class 1M according to EN 60825-1:1994 A2:2001). Pay attention
to stand to local regulations regarding laser safety.
It is not advisable to install the Laser Precipitation Monitor directly on a street, because it is, for
example, possible that water particles, whirled up by the vehicles, might lead to erroneous
measurements. In this case, we recommend to install the instrument with a respective distance and
height. At streets the alignment of the sensor should be not to the south, but at right angles with the
street (receiver head farthest away to the lane).
5.2 Mechanical Installation
Tools:
•
Allen wrench (Inbus) SW4
•
Combination wrench or ring spanner wrench SW10
•
Combination wrench SW16 und SW20
•
Tools to work in cables (for example: skinning tool, gripper for cable end sleeve)
•
Screw driver for slotted screws, blade width 2 and 6 mm
•
Tools for the shortening of straps
5.2.1 Mounting on Mast
The delivered mast holder of the Laser Precipitation Monitor is designed for a mast diameter of
48... 102 mm (1.9... 4 inch). The mast should be electro-conductive, and be connected to the
ground potential (foundation/grounding bound).Otherwise, the sensor is to be connected to the
ground potential by a cable with minimum 6mm² diameter. Due to its sensitivity the sensor is
susceptible to vibrations. Therefore, the mast diameter should be preferably large, and the mast
should be fixed on a concrete foundation by means of firmly welded-on struts. From a mast height
of approx. 2 m up the mast should be additionally fixed by three stay-wires.
Remark
: For models with supply 115VAC/230VAC
The mast should be electro-conductive, and be connected with the ground potential (base/ground
strip).Apart from that the sensor is to be connected to the ground potential by means of a cable
(>6mm²).
