Proline Promag 53
• The measuring device must be wired in accordance with the wiring diagrams and connection
labels. Interconnecting must be permitted.
• All parts of the measuring device must be integrated into the potential matching system of
the plant.
• The cables, tested cable glands and tested dummy plugs must suit the prevailing operating
conditions, e.g. the temperature range of the process. Housing openings that are not used
need to be sealed with dummy plugs.
• The measuring device can only be used in conjunction with fluids to which all the wetted parts
of the measuring device are adequately 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.
• 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. The Ex documentation on the CD-ROM 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. The symbol and name on the front page provides
information on the approval and certification (e.g.
nameplate also bears the documentation number of this Ex documentation (XA***D/../..).
• For measuring systems used in SIL 2 applications, the separate manual on functional safety
(on the CD-ROM) must be observed.
• 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.
