Note:
In this example, a shielded transmission
cable with a thickness of 0.75 mm
2
is used,
through which a current of 1.8 A max. can
be transmitted. It is recommended that the
shield be grounded.
The maximum transmission distance is
10 m if a VCTF wire with a thickness of
0.75 mm
2
is used instead of a shielded
cable for the transmission path.
