To ensure that the Voltage Clamping Module functions properly, a functional ground must be
connected to X1. Please note:
• The cables must be routed via the shortest possible path.
• Cross-section: 4 mm² to 16 mm²
• When a line filter is used, the functional ground should be located on the metallic
• In systems without a line filter, it should be connected on the PE busbar.
