Type 71 with fixed cable, 6 × 0.14 mm, shielded

Type 70 with M12 connector, 8-pole, A-coded

Route input, output, and supply lines separately and not parallel to one another

To connect the conductivity sensor, use the CR 4P-cable (see "Accessories") if possible; do not run 
the connecting cable close to current-carrying components or cables

Implement the cables continuously (not via terminal blocks or similar)

Do not connect any additional loads to the supply terminals of the sensor

Follow the instructions regarding the electrical connection in the operating manual for the transmitter 
used

Make sure that you always use safety devices that are independent of the device, and ensure that 
only qualified personnel configure the settings. In addition to incorrect installation, incorrectly set val-
ues on the transmitter can impair the performance of the downstream process or cause damage
