If the bus line is laid in the switch cabinet,
the screen must be connected to functio-
nal earth (PE).
When laying bus lines in the switch cabinet
it is normally sufficient if the screen of the
bus line is connected at least once to the
functional earth (PE).
If there are more significant sources of in-
terference, such as a frequency converter,
installed in the switch cabinet, the screen
must be connected to the functional earth
(PE) as close as possible to the device.
