2.4 Personnel qualification
The device may only be installed and commissioned by trained specialist personnel.
Specialized personnel are persons who are able to perform the work assigned to them due to their specialized training,
experience and knowledge of the country-specific regulations, applicable standards and guidelines. For explosion-
protected devices, the personnel must be trained or instructed or authorized to work on explosion-protected devices in
hazardous areas.
2.5 Signs/safety marking
The device is provided with a label. The label shows the type designation, serial number, year of manufacture, certificate
of approval number, Ex marking (including X for special conditions of use) and manufacturer.
With agency approval Ex d the device is provided with two warning label:
DO NOT OPEN WHEN ENERGIZED OR EXPLOSIVE ATMOSPHERE IS PRESENT
The operator must check the label, which is important for the use in potentially explosive atmospheres, at regular
intervals to ensure that it remains legible.
The outer packaging is labelled with the type designation, order number, item number and manufacturer's data.
2.6 Environmental protection
This device contain electrical components. The provisions of the Regulation on Registration, Evaluation, Authorization
and Restriction of Chemicals (REACH) 2006/1907/EC must be observed, the corresponding safety data sheets of the
manufacturers of the chemicals, are available for download on our website. At the end of the product life cycle, we
recommend to recycle the devices, as they are mostly made of stainless steel. Instructions for disassembly, material
separation and disposal can be found in chapters 11.1 and 0

Use in potentially explosive atmospheres according to Directive
2014/34/EU ATEX
3.1 Range of use:
Potentially explosive atmospheres Zone 0, 1 and 2, as well as 21, hazard due to gases and dry dusts.
The permissible environment has the usual oxygen content (21%), ambient pressure 80 kPa (0.8 bar) to 110 kPa (1.1
bar).
The requirements of the applicable standards EN IEC 60079-0, EN ISO 60079-1, EN 60079-31 or EN ISO 60079-11,
EN ISO 60079-26 were considered by an ignition hazard assessment. The applicable requirements of these standards
have been met.
The documentation has been filed with TÜV-Italia Gruppo TÜV Süd NB 0948 (see Declaration of Conformity).
Fluid Temperatures:
Permissible max. medium temperature in the
measuring system
≤ 70 °C
The medium temperature depends on the ignition temperature of the surrounding gas, vapours or dust, on the design
of the device, the surface, as well as the ambient temperature and other external heat sources. The device itself does
not have its own heat source.
