Power cable types
Preferred power cable types
This section presents 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 cabling Cable type
Yes Yes
„
„
PE
Symmetrical shielded (or ar-
mored) cable with three phase
conductors and concentric PE
conductor as shield (or armor)
Yes Yes
„
„
PE
Symmetrical shielded (or ar-
mored) cable with three phase
conductors and symmetrically
constructed PE conductor and a
shield (or armor)
Yes Yes
„
„
PE
Symmetrical shielded (or ar-
mored) cable with three phase
conductors and a shield (or ar-
mor), and separate PE conduct-
or/cable
1)
1) A separate PE conductor is required if the conductivity of the shield (or armor) is not sufficient for the PE use.
Alternate power cable types
Use as motor cabling and as
brake resistor cabling Use as input power cabling Cable type
Yes with phase conductor smaller
than 10 mm
2
(8 AWG) Cu, or mo-
tors up to 30 kW (40 hp).
Yes with phase conductor smaller
than 10 mm
2
(8 AWG) Cu.
PVC
Note: Shielded or armored cable,
or cabling in metal conduit is al-
ways recommended to minimize
radio frequency interference.
