Alternate Power Cable Types - ABB ACS580-04 Hardware Manual

Cable type
Symmetrical shielded (or armored)
cable with three phase conductors
and a shield (or armor), and separ-
ate PE conductor/cable
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

Cable type
PVC
Four-conductor cabling in PVC con-
duit or jacket (three phase conduct-
ors and PE)
EMT
Four-conductor cabling in metal
conduit (three phase conductors and
PE), eg, EMT, or four-conductor ar-
mored cable
Well-shielded (Al/Cu shield or ar-
mor) four-conductor cable (three
phase conductors and a PE)
PE
A single-core cable system: three
phase conductors and PE conductor
on cable tray
L1 L2
L2 L3 L3 L1 L1
Preferable cable arrangement to
avoid voltage or current unbalance
between the phases
Use as input power cabling

WARNING!
If you use unshielded
single-core cables in an IT
network, make sure that the
non-conductive outer
L3
sheath (jacket) of the cables
L2
have good contact with a
properly grounded conduct-
ive surface. For example,
install the cables on a prop-
erly grounded cable tray.
Otherwise voltage may be-
come present on the non-
conductive outer sheath of
the cables, and there is
even a risk of an electric
shock.
Guidelines for planning the electrical installation 73
Use as motor cabling
Yes
Use as motor cabling
Yes with phase conductor smaller
(8 AWG) Cu. than 10 mm
up to 30 kW (40 hp).
Note: Shielded or armored cable, or
cabling in metal conduit is always
recommended to minimize radio fre-
quency interference.
Yes with phase conductor smaller
than 10 mm
up to 30 kW (40 hp)
Yes with motors up to 100 kW
(135 hp). A potential equalization
between the frames of motor and
driven equipment is required.
