Safety Conventions - Endress+Hauser Proline Promass 40 Brief Operating Instructions

Safety instructions
• All parts of the measuring device must be included in the potential matching of the system.
• Cables, tested cable glands and tested dummy plugs must be suitable for the prevailing
operating conditions, e.g. temperature range of the process. Housing openings which have not
been used must be sealed with dummy plugs.
• The measuring device must only be used with fluids, against which all wetted parts of the
measuring device are sufficiently resistant. With regard to special fluids, including fluids used
for cleaning, Endress+Hauser will be happy to assist in clarifying the corrosion-resistant
properties of wetted materials.
However, minor changes in temperature, concentration or in the degree of contamination in
the process may result in variations in corrosion resistance.
For this reason, Endress+Hauser does not accept any responsibility with regard to the
corrosion resistance of wetted materials in a specific application. The user is responsible for
the choice of suitable wetted materials in the process. A sensor version which allows the
sensor housing be monitored should be used for critical fluids.
• Hazardous areas: Measuring devices for use in hazardous areas are labeled accordingly on the
nameplate. Relevant national regulations must be observed when operating the device in
hazardous areas.
• Hygienic applications: Measuring devices for hygienic applications have their own special
labeling. Relevant national regulations must be observed when using these devices.
• Pressure instruments: Measuring devices for use in systems that need to be monitored are
labeled accordingly on the nameplate. Relevant national regulations must be observed when
using these devices. The documentation on the CD-ROM for pressure instruments in systems
that need to be monitored is an integral part of the entire device documentation. The
installation regulations, connection data and safety instructions provided in the Ex
documentation must be observed.
• Endress+Hauser will be happy to assist in clarifying any questions on approvals, their
application and implementation.
