ABB PM554-T-ETH Serial Link Module

Provide a potential equalisation cable with a suitable cross-section between potentials (control cabinets) if the Micro Panel GF-1 and the communication partner are installed in different control cabinets or at different PE potentials (zero conductor potentials), and if the cable shield is directly or indirectly connected at both ends to the protective earth conductor. 

This will prevent the occurrence of excessive compensation 

currents on the shield and shield connections, as may occur in the event of a possible shorting of a device on the protective earth system. These kinds of compensation currents of normally 50 Hz even occur in normal operation and do not represent a problem for data transmission. However, they may cause the destruction of the shield contacts, particularly in the event of shortcircuits in the environment.
