4.1 General instructions
Protect your instrument against moisture ingress through the following
measures:
• Use a suitable connection cable (see chapter " Connectingto
power supply")
• Tighten the cable gland or plug connector
• Lead the connection cable downward in front of the cable entry or
plug connector
This applies mainly to outdoor installations, in areas where high
humidity is expected (e.g. through cleaning processes) and on cooled
or heated vessels.
Note:
Make sure that during installation or maintenance no moisture or dirt
can get inside the instrument.
To maintain the housing protection, make sure that the housing lid is
closed during operation and locked, if necessary.
Note:
For safety reasons, the instrument must only be operated within the
permissibleprocessconditions.Youcannddetailedinformationon
the process conditions in chapter " Technical data" of the operating
instructions or on the type label.
Hence make sure before mounting that all parts of the instrument ex-
posed to the process are suitable for the existing process conditions.
These are mainly:
• Active measuring component
• Processtting
• Process seal
Process conditions in particular are:
• Process pressure
• Process temperature
• Chemical properties of the medium
• Abrasionandmechanicalinuences

4.3 Mounting preparations, mounting strap
The mounting strap is supplied unassembled (optionally) and must be
screwed to the sensor before setup with three hexagon socket screws
M5 x 10 and spring washers. Max. torque, see chapter " Technical
data".Requiredtools:Allenwrenchsize4.
Therearetwodierentvariantsofscrewingthestraptothesensor,
see following illustration:

4.4 Mounting instructions
Radar sensors for level measurement emit electromagnetic waves.
Thepolarizationisthedirectionoftheelectricalcomponentofthese
waves.
Thepolarizationdirectionismarkedbyanoseonthehousing,see
following drawing:
1
Fig. 12: Position of the polarisation
1 Nose for marking the direction of polarisation
Information:
Whenthehousingisrotated,thedirectionofpolarizationchanges
andhencetheinuenceofthefalseechoonthemeasuredvalue.
Please keep this in mind when mounting or making changes later.
Mount the instrument at least 200 mm (7.874 in) away from the vessel
wall.
