Specific Conditions Of Use ("X" Identification); Installation - Vega VEGAPULS 6X Series Safety Instruction

4 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 zone 0/1 (EPL Da/Db) instruments.
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 zone 0/1 (EPL Da/Db) instrument 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.
•
If grounding of the cable screening is necessary, this must be carried out acc. to the valid stand-
ards and regulations, e.g. acc. to IEC/EN 60079-14.
•
Close the housing lid (s) up to the stop before starting operating, to ensure the IP protection rat-
ing specified on the type label.
