3.2 General Installation Information
Mounting Conditions
The central unit LDS 6 should be placed on a location which is dust-free and as free as
possible from vibrations. The distance between the central unit and the measurement point,
i.e. the sensor, may not exceed 1000 meters (3,280 ft) for the non ATEX version and
600 m (1,970 ft) for the ATEX version.
During operation the permissible surrounding air temperature is 5 °C (41 °F) to 45 °C
(113 °F), with a relative humidity of maximum 85% non-condensing, around the central unit.
Also ensure that the unit is not exposed to direct solar radiation. If these conditions can't be
fulfilled the LDS 6 must be installed in a cabinet with controlled environment.
Note
As condensing is normally a problem when moving the device from outside to inside a
building it is recommended that the device should be adapted to room climate for a couple of
hours before starting it.
The back of the unit must be freely accessible. There should be at least 10 cm (4 ") of free
space behind the LDS 6 to accommodate the signal and hybrid cables. To meet the safety
requirements for air convection and cooling there must be a free space of at least 5 cm (2 ")
above and at least 3 cm (1 1/4 ")below LDS 6.
For detailed information on the sensor installation, please refer to the sensor manual
corresponding to your system setup.
