    The measured values are read out in various ways. For one, all measured values are filed in registers that can be read out via Modbus. Additionally, they can be sent to a PC via the Config interface. This requires the WAGO USB Communication Cable (750-923). The measured values are then configured and vi- sualized on the PC with the Interface Configuration Software.

    A low-impedance connection between shielding and ground achieves better shielding performance. For this purpose, connect the shielding over a large surface area, e.g., using the WAGO Series 790 Shield Connection System. This is especially recom- mended for large-scale systems where equalizing or high impulse currents may occur.
