5.3.3 Movable EMC cable screw glands
In con
fi
ned spaces it is often necessary to install the frequency converter as close as possible
underneath the ceiling, a steel girder or similar. Since it is dif
fi
cult to feed the cables into the uipper
EMC screw cable glands under these circumstances, these can be mounted alternatively on the right-
hand side of the frequency converter. The EMC cable screw glands and the plastic caps must be
switched for this (see
fi
g.).

5.4 Protective ground connection
The device has a de
fi
ned leakage current of > 3.5 mA according to DIN EN 60990. For this reason its
connection has to be
fi
x. According to EN 50178 point 5.2.11 or 5.3.2.1 the earth conductor has to
have a cross section of 10 mm
²
or more. If an earth conductor with a cross section < 10 mm
²
is used,
there has to be a second earth conductor. Then the cross section of both earth conductors added has
to be 10 mm
²
or more. For the connection of the earth conductors there are threaded bolts M6 at the
frequency inverter (see picture).
