Caution!
If high-energy transients occur when using long signal cables, we recommend connecting a suit-
able overvoltage protection (e.g. E+H HAW560/562).
Use shielded signal lines for serial interfaces!
4.2.1 Cable specification, Spring terminals
All connections on the rear of the device are designed as screw or spring terminal blocks with
