Yes.Yes.
Symmetrical shielded cable with
three phase conductors and sym-
metrically constructed PE conduct-
or, and a shield.
Yes. A separate PE conductor is
required if the shield does not agree
with the PE conductor requirements.
Yes. A separate PE conductor is
required if the shield does not agree
with the PE conductor requirements.
Note:
If the shield size is smaller than
10 mm
2
Cu (or 16 mm
2
Al), you
need two PE conductors typically,
for example, the shield and a separ-
ate conductor/cable. This is due to
the safety regulations related to the
leakage current. See IEC/EN 61800-
5-1, or the drive safety instructions
for more information.

■ Power cable shield
If the cable shield is used as the sole PE conductor, make sure that its conductivity agrees
with the PE conductor requirements.
