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).
