CAUTION!
Prior to commissioning, the pressure transmitter must be subjected to a visual inspection.
Leaking fluid is indicative of damage.
Check the diaphragm of the process connection for any damage.
Only use the pressure transmitter if it is in perfect condition with respect to safety.

6.1 Mechanical mounting

Remove the protective cap not until shortly before installation.
Ensure that the diaphragm of the process connection is not damaged during installation.
The sealing faces at the instrument and the measuring point always have to be clean.
Carry out the required mounting steps properly, depending on the process connection.
Carry out the mounting steps described in chapter 6.2 "Electrical mounting" properly.
Mounting instructions for instruments with EHEDG and 3-A
Observe the following instructions, especially for EHEDG-certified and 3-A-compliant instruments.
To maintain the EHEDG certification, one of the EHEDG-recommended process connections must be used. These
are marked with the logo in the data sheet.
To maintain the conformity to the 3-A standard, a 3-A-compliant process connection must be used. These are
marked with the logo in the data sheet.
Mount the instrument with minimal dead space and able to be cleaned easily.
The mounting position of the instrument, welding socket and instrumentation T-piece should be designed to be
self-draining.
The mounting position must not form a draining point or cause a basin to be formed.
With the process connection via an instrumentation T-piece, the branch L of the T-piece must not be longer than the
diameter D of the T-piece (L ≤ D).
