1. Connect the pipe flanges and transmitter via the ground cable.
2. Route the shielding of the signal lines via a capacitor (recommended value 1.5µF/
50V).
3. Device connected to power supply such that it is floating in relation to the protective
earth (isolation transformer). This measure is not required in the case of 24V DC
supply voltage without PE (= SELV power unit).
