2.3.2 Wiring the IEC 62591 Module
Figure 2-5
provides a wiring diagram for the IEC 62591 module.
You must connect an RS-485 cable between the RS-485 port on the
module, and the Field Link. This requires a Belden 2-twisted pair cable.
Table 2-1
shows connections for the twisted pair cable. You must also
connect termination jumper wires as shown in
Figure 2-6.
