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.
