Comment:
We recommend that shielded output cables be used with the shields connected to the functional ground at one end.
Important
If the flowmeter sensor is equipped with a preamplifier for low conductivity or in nominal diameter DN 1 ... DN 8
(1/25 ... 5/16"), the shieldings of the signal wires must be connected to terminals U+ and U- on both the flowmeter
sensor and the transmitter.
