6.4.3.2 X1 functional ground
X1 functional ground
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
installation panel in the immediate vicinity of the line filter.
● In systems without a line filter, it should be connected on the PE busbar.
