It is important that the installer ensures that
TNV connections are only connected to
the PSTN and SELV circuits are only
connected to other circuits designated as
SELV circuits.
+
Interconnection circuits should be such
that the equipment continues to comply
with the requirements of 4.2 of EN 41003
for TNV circuits and 2.3 of EN 60950 for
SELV circuits, after making connections
between circuits.
