)
1. Connect the ground disks to the ground terminal via the ground cable.
2. Connect the ground disks to ground potential.

Pipe with a cathodic protection unit
This connection method is only used if the following two conditions are met:
• Metal pipe without liner or pipe with electrically conductive liner
• Cathodic protection is integrated in the personal protection equipment

Prerequisite: The sensor is installed in the pipe in a way that provides electrical insulation.
1. Connect the two flanges of the pipe to one another via a ground cable.
2. Connect the flange to the ground terminal via the ground cable.
3. Route the signal line shielding via a capacitor (recommended value 1.5 µF/50 V).
4. Connect the device to the power supply such that it is floating in relation to the ground
potential (PE), (this step is not necessary if using a power supply without ground
potential (PE)).
