Passive Components for RS-485 Networks

Note

If you connect to screw terminals, the stranded cores must be fitted with wire-end ferrules (0.25 mm2 complying with DIN 46228). Use only wire-end ferrules made of materials with permanently stable contact properties, for example copper with a tin-plated surface (not aluminum).

The bus connector 6ES7 972-0BA30-0XA0 cannot be connected to the stranded cores.
