CNCR-230 • Two-wire 4-20 mA/HART

11

Note:

Shielded cable generally necessary in HART multidrop mode.

Note:

If the temperatures are too high, the cable insulation can be damaged.

We recommend connecting the cable screening to ground potential at one end on the supply side

when using shielded cable.

5.2 Connecting

Fig. 11: Connection

Connect the instrument as described in the following wiring plan.
