• All parts of the device must be included in the potential equalization of the system.
• Cables, certified cable glands and certified dummy plugs must be suitable to withstand the
prevailing operating conditions, such as the temperature range of the process. Housing
apertures that are not used must be sealed with dummy plugs.
• The device should only be used for fluids to which all the wetted parts of the 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.
• When hot fluid passes through the measuring tube, the surface temperature of the housing
increases. In the case of the sensor, in particular, users should expect temperatures that can
be close to the fluid temperature. If the temperature of the fluid is high, implement sufficient
measures to prevent burning or scalding.
• 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.
0
Europe,
2
USA,
1
Canada). The
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.
