2.1 Generalities
The instrument may only be installed and commissioned by specialized person-
nel familiar with the installation, commissioning and operation of this product.
Specialized personnel are persons who can assess the work they have been

imum overload.
Illustration 6:
Shutoff valve.
The device is set ex-works for vertical installation, however any installation posi-
tion is possible.
To guarantee safe working conditions during installation and maintenance, suit-
able stop valves must be fitted in the system (see accessories). By means of
the manometer shutoff, the unit
• Can be depressurized or taken out of operation.
• Be disconnected from the power supply within the applicable system for re-
pairs or inspections.
2.2 Process connection
• By authorized and qualified specialized personnel only.
• The pipes need to be depressurized when the instrument is being connec-
ted.
• Appropriate steps must be taken to protect the device from pressure surges.
• Check that the device is suitable for the medium being measured.
• Maximum pressures must be observed (cf. Tech. data)
WARNING
Earth connection via the system earth
During assembly, ensure that the earth connection between the pressure trans-
mitter and the system earth is ensured. The connection to the system earth is
realised via the process connection. Therefore, never use an insulated Teflon
tape or similar. Design the process connection acc. to EN 837 and use a suit-
