Note
• We recommend that shielded output cables be used with the shields connected to the functional ground at one end.
• If the sensor is equipped with a preamplifier for low conductivity or in nominal diameter range of DN 1 to DN 8 (¹⁄₁₀ to ⁵⁄₁₆”),
the shieldings of the signal wires must be connected to terminals U+ and U− on both the sensor and the transmitter.
