PE
Symmetrical shielded (or ar-
mored) cable with three
phase conductors and a
shield (or armor), and separ-
ate PE conductor/cable
1)
1)
A separate PE conductor is required if the conductivity of the shield (or armor) is not sufficient for the
PE use.

Note: Shielded or armored
cable, or cabling in metal
conduit is always recommen-
ded to minimize radio fre-
quency interference.

Yes
Four-conductor armored
cable (three phase conduct-
ors and PE)
Yes with motors up to 100 kW
(135 hp). A potential equaliza-
tion between the frames of
motor and driven equipment
is required.

Armor may act as an EMC shield, as long as it provides the same performance as a concentric EMC
shield of a shielded cable. To be effective at high frequencies, the shield conductivity must be at least
