4. po Connection technology Connection procedure If screened cable is necessary connect the cable screen on both ends to ground potential In the sensor the screen must be connected directly to the internal ground terminal The ground terminal on the outside of the housing must be connected to the potential equalisation low impedance If potential equalisation currents are expected the connection on the processing side must be made via a ceramic capacitor e g 1 nF 1500 V The low frequency potential equalisation currents are thus suppressed but the protective effect against high frequency interfer ence signals remains Warning Within galvanic plants as well as vessels with cathodic corrosion protection there are considerable potential differences Considerable equalisation currents can be caused via the cable screen when the screen is earthed on both ends To avoid this the cable screen must only be connected to ground potential on one side of the switching cabinet in such applications The cable screen must not be connected to the internal ground terminal in the sensor and the outer ground terminal on the housing not to the potential equalisation Information The metal parts of the instrument antenna transmitter concentric tube etc are conductive connected with the inner and outer ground terminal on the housing This connection exists either directly metallic or with instruments with external electronics via the
