2.3 Flammable products
Atmospheric conditions:
An explosive atmosphere is a mixture of air and flammable gases, vapours, mists or dusts under
atmospheric conditions. It is defined by the following values
Tatm = -20...+60°C / -4...+140°F and Patm = 0.8...1.1 bar / 11.6...15.9 psi.
Operation outside the specified above standard atmospheric conditions is permitted only via risk
assessment of the user and additional measures, as necessary.
Operating conditions:
Outside of atmospheric conditions, the explosion protection according to directive 2014/34/EU
(ATEX) – regardless of the zone assignment – is not applicable due to the lack of key safety data.
2.4 Equipment category
Pressure transmitters are rated in the Categories II 1G or EPL Ga for use in zone 0 and II 1D or
Da for use in zone 20.

3.1 Mounting
Installation and setup must be carried out according to the applicable installation standards
(e.g. EN 60079-14 or IEC 60079-14) by qualified personnel trained in explosion protection. The
information given in the manuals and the supplementary instructions must be observed at all
times.
Install pressure transmitters so that:
•they are not in a pneumatic flow.
•excessive dust deposits (over 5 mm) and complete dust coverage are prevented.
•there is no danger from mechanical impact effects.
CAUTION!
The manufacturer is not liable for any damage resulting from improper use or use other than the
intended purpose. This applies in particular to hazards due to insufficient corrosion resistance
and suitability of the materials in contact with product.

4.1 General notes
Circuits
The circuits are designed in protection type "intrinsically safe".
The connecting cables should be selected according to the applicable installation standards (e.g.
EN 60079-14) and the maximum operating temperature. Ensure that no residual current can
form between separate intrinsically safe signal circuits.
•The connecting cables must be fixed and laid so they are sufficiently protected against
damage.
•Devices with plugs are to be mounted in that way that protection degree IP20 is maintained.
•All cores that are not used must be securely connected to the ground potential of the
hazardous area or carefully insulated against each other and against ground (test voltage ≥
500 Veff).
•Lay cables so as to ensure that there is sufficient distance between surfaces of the
measuring unit and the connecting cable.
•Supplied blind plugs / cable entries guarantee protection against foreign bodies and water
(protection category) IP66 / 67 according to EN 60529 in the temperature range
Tamb = -40...+100°C / -40...+212°F.
•The outer diameter of the connecting cable must be within the sealing range of the cable
entry (8...13 mm /0.31...0.51").
•Unused cable entries are to be closed (>IP66 / 67).
Ensure that all seals are tight.
4.2 Power supply
The pressure transmitter does not require a separate power supply. The required supply for the
built-in electronics is provided via the 4...20 mA current output.
Overvoltage protection
If the pressure transmitter is used as electrical equipment of category 1 G, then a suitable
overvoltage protection device must be connected in series (attend the valid regulations for
operating safety as well as EN60079-14).
4.3 Inputs/outputs
The terminal assignment of the built-in electrical equipment is described in the standard
documentation. The pressure transmitter signal circuits may only be connected to certified
intrinsically safe slave units or circuits. For more information refer to chapter "Electrical data".
4.4 Grounding and equipotential bonding
If the device is not sufficiently electrostatically grounded via the process cables, an additional
ground connection must be established using the ground terminal.
Any existing cable shields should be connected to ground according to applicable installation
regulations (EN 60079-14). A terminal connection in the terminal compartment permits a short
way grounding of the cable shields.

5.1 Start-up
Start-up is only permitted when the pressure transmitter:
•is correctly installed in the system and connected.
•has been checked for the proper state with regard to its installation and connection
requirements.
The user of the system must have it checked before start-up in compliance with the national
regulations for checks before startup.
5.2 Operation
Pressure transmitter must be operated in such a way that they remain within the maximum and
minimum permissible temperatures and pressures and the electrical limit values.
Pressure transmitter may only be operated if the equipment parts necessary for safety are
effective in the long run, and are not rendered inoperable during operation.
For more information refer to chapter "Dismantling".
5.3 Electrostatic charge
A caution label points out the safety measures that must be taken with regard to electrostatic
charges during operation.
In order to avoid ignition hazards due to electrostatic charge, the pressure transmitter
may not be used in areas with:
•processes that generate strong charges,
•mechanical friction and cutting processes,
•spraying of electrons (e.g. in the vicinity of electrostatic painting systems).
In order to avoid ignition hazards due to electrostatic charge, the connecting cables must be
permanently laid and the pressure transmitter may not be dry cleaned.
Figure 5-1: Warning note
Attention!
Plastic parts
There is a danger of electrostatic charge!

6.1 Maintenance
Maintenance work of a safety-relevant nature within the meaning of explosion protection may
only be carried out by the manufacturer, his authorised representative or under the supervision
of authorised inspectors.
To maintain proper condition, regular inspections are required for systems in hazardous areas.
The following checks are recommended:
•Checking the housing, the cable entries and the feed lines for corrosion and/or damage.
•Checking the measuring unit and the piping connections for leakage.
•Checking the measuring unit and the indicator for dust deposits.
•Including the pressure transmitters in the regular pressure test of the process line.
6.2 Dismantling
Removal and installation are the responsibility of the operator.
Before disconnecting the electric connecting cable of the device, make sure that all cables
leading to the indication unit are isolated from the ground of the hazardous area. This also
applies to functional earthing conductors (FE) and equipotential bonding conductors (PA).
WARNING!
• Pressurised pipes have to be depressurised before removing the measuring unit.
• In the case of environmentally critical or hazardous products, appropriate safety precautions
must be taken with regard to residual liquids in the measuring unit.
• New gaskets have to be used when re-installing the device in the piping.
