3.6.2 How to connect the electrical cables
Cable glands are supplied on customer demand. If you supply the cable glands, this part must
have a degree of ingress protection IP
≥
6X (IEC 60529).
•
Do not remove more than 6 mm / 0.2
¨
of insulation from the wire.
•
Connect the load resistor to the positive terminal of the power supply
•
Ground the negative connection.
•
If the load resistor has to be connected to the negative terminal, the loop resistance must not
be more than 350 ohms.
3.6.3 Supply voltage
Level transmitter with the 4...20 mA output option
Level transmitter with the PROFIBUS PA or FOUNDATION fieldbus output option
For more data, refer to
Maximum intrinsically-safe values for the electrical circuit
