5.3.3 Connect PE wire on the device
with appropriate cable lug to threaded stud according
to torque given in section 3.5.2.
5.3.4 Connect shielding for shielded cables
When using shielded cables, the customer must en-
sure to properly connect the shielding of the cables
between input and output. Proper continuity of
shielding is important for EMC purpose and cannot
be only connected through the PE of the filter/reac-
tor. The customer must ensure that the cable shield-
ing is connected with as much surface as possible to
a wide connector like a bus bar or rail both on the in-
put and output cable. An example shielding connec-
tion system is given in Figure 8 in section 3.5.
