1 As defined by standard DIN 19234.

2 Add external resistor across field device for wire-off detection (0.4 mA) - (about 15

…20 K).

3 Add a jumper between 50 mV Sel and N (frequency - channel 0 = 4

to 6, channel 1 = 9 to 11;

gate - channel 0 = 21 to 23, channel 1 = 28

to 26).

4 Connect cable shields to shield busbar or shield terminating feedthroughs.

5 All GND terminals are internally connected together.
