6.5.2 RS-485 interface
6.5.2.1 Connecting the RS-485 interface
Connect the interface as follows:
1. For connecting the interface use only a cable with these properties:
– LJYCY (TP), 4 × 2 × 0.8, maximum overall bus length 1000 m.
2. Use a shielded cable to connect the interface to terminals 29, 30, 31 of the
main board in the control cabinet.
– For connecting the interface, see chapter 6.5 "Elektrischer Anschluss"
on page 10 .
3. When using the device with a control centre not supporting an RS-485
interface (RS-232, for example), you must use a corresponding adapter.
