1. Check if all parts are delivered as shown in Figure 16. For every configuration (single converter
as shown in Figure 16a and multi converter array as in Figure 16b) a termination box (resistance
to terminate the RS485) and a connector box (wiring) is needed.
2. For communication with RS485 check the address settings of the potentiometers on the front
panel of the converter (see
"High ADRS" x 10 + "Low ADRS" x 1

Specification
Not connected.
24 VDC ± 10% / 270 mA / Inrush Peak 4.9 A within 180 µs
Note: Usage of twisted pairs in a shielded cable recommended.
Field Ground. See note in installation Section 3.2.2
RS485 with MODBUS protocol
Digital communication in a sensor array or configuration with service SW.
Note: Usage of twisted pair wires in a shielded cable recommended.
RS485 ground. If possible, to be connected to the ground of the RS485 master.
Note 1: Can be led in the same cable as TRX+/TRX-.
