12 Shield grounding selection
With the following patch panels you can select the type of
shielding with a jumper:
– FL-PP-RJ45-SCC
– FL-PP-RJ45-SC
– FL-PP-RJ45-LSA
– FL-PP-RJ45/RJ45
By default upon delivery, the jumper is inserted and the
shield is positioned directly on the ground potential (PE).
With this arrangement, there is a low-ohmic electrical con-
nection between the shield and the ground potential.
If the jumper is removed, the shield is connected to the
ground potential via an RC combination. A high-ohmic resis-
tance parallel to a capacitor ensures that high-frequency
disturbances are delivered effectively to the ground poten-
tial without the presence of a low-ohmic electrical connec-
tion.
A single-sided grounding of the shield between two patch
panels is best suited for suppressing electrical fields and
ground loops.

With FL-PP-RJ45/RJ45-B, the shielding is not
connected with the DIN rail.
With FL CAT5 TERMINAL BOX, the shielding is
fundamentally connected to the DIN rail via the
universal snap-on foot.
