8.3.4 Protective Earth Connection
Protective Earth connection of the system components is a safety measure per IEC 60204. Ensure the proper
grounding of all components with the PE rail in the control cabinet as reference potential. Connect each ground
individually with the intended grounding cable (neutral point connection).
The leakage current from AKD2G against PE is more than 3.5 mA. In accordance with EN 61800-5-1, the PE
connection must therefore either be double implemented or a connection cable with >10 mm² cross-section used.
In order to keep the impedance as low as possible, we recommend a copper earthing strap for the PE connection on
the PE block.
Wire the PE connections immediately after installing the devices as the first electrical connection. Now you
insert all the other lines and connectors. For disassembly, release the PE connections as the last
connection.
For the use of residual current protective devices (RCD), refer to (➜ # 19).
