Protective ground connection
In accordance with the de
fi
ned networks in DIN EN 60990 the frequency inverter has a leakage
current > 3.5 mA and must therefore be permanently connected. In accordance with EN 50178 item
5.2.11 and 5.3.2.1, the PE conductor connection must have a cross-section of at least 10 mm
²
. In the
case of PE conductors < 10 mm
²
, an additional PE conductor must be connected. The cross-section
must correspond at least to the cross-section of the PE conductor on the connecting lead. ZAdyn4B
M6 threaded bolts are available on the ZETADYN for connecting the PE conductors (see
fi
g.).
