Alternate Power Cable Types - ABB ACS880 Manual

Cable type
Symmetrical shielded (or ar-
mored) cable with three phase
conductors and symmetrically
constructed PE conductor and a
shield (or armor)
Symmetrical shielded (or ar-
mored) cable with three phase
conductors and a shield (or ar-
mor), and separate PE conduct-
1)
or/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

Exception for ACS880-304LC...+A019 diode supply modules: These power cable types
are not allowed.
Cable type
EMT
Four-conductor cabling in metal
conduit (three phase conductors
and PE). For example, EMT, or
four-conductor armored cable
Shielded (Al/Cu shield or armor)

Yes
Yes
Use as motor cabling and as
brake resistor cabling
Yes with phase conductor smaller
2
than 10 mm (8 AWG) Cu, or mo-
tors 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.
