Incorrect operation of the system, e.g. due to instruction errors, can lead to personal injury or
damage to the system.
a) Access to the user manual by the operating and maintenance personnel must be absolutely
ensured at all times.
b) A copy of the system documentation including the user manual must therefore be kept
either on the system or in a suitable and accessible location.
NOTICE

2 Description
2.1 Intended use
The intended use of the Tapping point EM75 is the removal of a gas from a system. In this pro-
cess, the outlet pressure or the flow rate can be adjusted.
Tapping points of type EM75 are suitable for flammable gases, non-flammable gases, non-cor-
rosive gases and for oxygen up to gas quality 6.0.
The permissible gas types and pressure ranges are each specified on the label (see "Identifica-
tion / label").
The equipment versions of the Tapping points without electrical components may be used in an
explosion hazard zone as they do not have separate ignition sources (ignition hazard assess-
ment according to DIN EN ISO 80079-36).
Tapping points with electrical components that are suitable for use in an explosion hazard zone
are marked on the label according to EU Directive 2014/34/EU.
To be able to use the Tapping points as intended, all persons working with it must comply with
the specifications of the relevant user manual.
The area in which hazards can occur when used as intended is the area around the Tapping
points. The danger zone changes depending on the system status and use.
2.2 Misuse
Any improper use constitutes misuse. Tapping points may only be used for the specified gases
and in the specified pressure range. Tapping points with electrical components without marking
according to EU Directive 2014/34/EU may not be used in an explosion hazard zone.
Furthermore, the following operating conditions are regarded as misuse:
– Use for gases in their liquid phase
– Failure to carry out inspection and maintenance work
– Pressurisation in reverse (opposite to the flow direction)
– Operation with gases that are not specified on the label
– Operation outside the permissible technical limit values
– Failure to heed and comply with any applicable legal regulations and other provisions
– Non-observance of the user manual
– Failure to heed the information on the label and in the product data sheet
2.3 Identification / label
The label is located on theon the mounting plate of the Tapping point.
The label provides the following details:

2.4 Environment
2.4.1 Temperatures
Normal temperatures expected in a production area are assumed when operating the system:
-20°C to +60°C.
The air humidity must be below 60 % rel. humidity to prevent condensation. The operating tem-
perature depends on the gas used.
2.4.2 Degree of cleanliness
Access to the system and to the escape and rescue routes must not be blocked.
The product should be kept clean (dust-free).
A suitable purge gas must be used, taking into account the quality and properties of the process
gas.
Compressed air must be used for the control air at least class 5 according to ISO 8573-1.
2.4.3 Emissions
The A-rated sound pressure level does not exceed the value of 70 dB(A). It is not necessary to
wear hearing protection.
The waste gas line or a burst disc line must not end in areas where the escaping process gas
poses a hazard to persons or the environment.
Further emissions in the form of vibrations, radiation, vapours, dusts and waste water do not oc-
cur in the regular operation of the product.
2.5 Standards and laws
The design and construction of the Tapping point is subject to the following standards and dir-
ectives:
2006/42/EC Machinery Directive
2014/68/EU Pressure Equipment Directive
2014/34/EU ATEX directives
DIN EN ISO 12100:2010 Safety of Machinery
Safety data sheet for the gases used Process gas and auxiliary media
Various additional laws, regulations and guidelines must be complied with when handling pres-
surised gases. Find out about the laws, regulations and guidelines that apply in your location.
