2. Route the shielding of the signal cables 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).
4. Use the "Measurement isolated from ground" option, while observing the operating
conditions for measurement isolated from ground.
