Specific conditions of use ("X" identification)
The following list describes the special operating conditions of VEGAPULS 6X.
•
In the application the following applies to the radar sensors VEGAPULS 6X in the versions with
Aluminium/Titanium:
– Installation must be carried out in such a way that the generation of sparks as a result of impact
and friction processes between Aluminium/Titanium and steel is excluded. This excludes stain
-
less steel without rust particles.
•
Certain components of the radar sensor VEGAPULS 6X can charge electrostatically. These
include: Plastic housings, non-grounded metal parts, plastic antennas. For details, refer to chap-
ter "
Electrostatic charge (ESD)
" of these safety instructions.
•
To avoid the risk of electrostatic charging of metal parts, the VEGAPULS 6X must be connected
to the potential equalization (transition resistance ≤ 1 MΩ).
•
All parts of VEGAPULS 6X in contact with the medium must only be used in such a medium
against which the materials are sufficiently resistant.
•
VEGAPULS 6X with rinsing connection: It must be ensured that the IP67 degree of protection
is provided at the connection to the reflux valve when used as category 1/2G equipment. After
removing the reflux valve or the rinsing facility on the refölux valve, the opening must be closed
with a suitable screw plug so that the IP67 degree of protection is maintained.
•
VEGAPULS 6X with swivelling holder: It must be ensured that the IP67 degree of protection is
maintained when operating as category 1/2G equipment after aligning the antenna using the
swivelling holder and after screwing on the tension flange.
•
Ambient temperature

You can find the details in chapter "
Thermal data
" of these safety instructions.

Installation
•
The installation of the device must only be carried out by qualified personel.
•
The staff must be trained in explosion protection and familiar with the relevant valid regulations.
•
Make sure when working on the instrument that there is no explosive atmosphere present. The
supply circuits should be voltage-free, if possible.
•
Install the instrument in accordance with the manufacturer specification and the applicable
national regulations, e.g. planning and installation in accordance with IEC/EN 60079-14.
•
The devices must be integrated into the local potential equalization.
