Note: A shielded cable with a
2
thickness of 0.75 mm
min. must be used for sig-
nal transmission. It is rec-
ommended that the shield
be grounded.
Note: In this example, a
shielded transmission
cable with a thickness of
2
0.75 mm min. is used,
through which a current
of 1.8 A max. can be
transmitted. It is recom-
mended that the shield
be grounded.
