Power cable types
Preferred power cable types
This section shows the preferred cable types. Make sure that the selected cable
type also complies with local/state/country electrical codes.
Use as motor cabling and as
brake resistor cabling
Use as input power cablingCable type
YesYes
Symmetrical shielded (or ar-
mored) cable with three
phase conductors and con-
centric PE conductor as
shield (or armor)
YesYes
Symmetrical shielded (or ar-
mored) cable with three
phase conductors and sym-
metrically constructed PE
conductor and a shield (or
armor)
YesYes
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.
