Alternative Power Cable Types - ABB ACS800-U1 Hardware Manual

Alternative power cable types


Power cable types that can be used with the drive are represented below.
Recommended
Symmetrical shielded cable: three phase
conductors and a concentric or otherwise
symmetrically constructed PE conductor, and a
shield
PE conductor
and shield
A four-conductor
system: three phase
conductors and a
protective conductor
The following power cable type is not allowed.
PE
Shield
PE
PE
Not allowed for motor cables
Symmetrical shielded cable with individual shields for each phase conductor
is not allowed on any cable size for input and motor cabling.
Planning the electrical installation 51
A separate PE conductor is required if the
conductivity of the cable shield is < 50%
of the conductivity of the phase
conductor.
