Alternative power cable types
The power cable types that you can use with the converter are shown below.
Symmetrical shielded cable with three phase conductors and a concentric PE
conductor as shield. The shield must meet the requirements of IEC 61800-5-1.
Check with local / state / country electrical codes for allowance.

PE
Symmetrical shielded cable with three phase conductors and a concentric PE
conductor as shield. A separate PE conductor is required if the shield does not
meet the requirements of IEC 61800-5-1.
„
„
PE
Symmetrical shielded cable with three phase conductors and symmetrically con-
structed PE conductor, and a shield. The PE conductor must meet the requirements
of IEC 61800-5-1.

Power cable types for limited use
A four-conductor system (three phase conductors and a protective conductor on
a cable tray) is not recommended for cabling.

PE
Not allowed power cable types
A four-conductor system (three phase conductors and a PE conductor in a PVC
conduit)
PVC
Corrugated cable with three phase conductors and a protective conductor or cable
in EMT conduit
EMT
A well-shielded (Al/Cu shield) four-conductor system (three phase conductors and
a PE conductor or four conductors)
Symmetrical shielded cable with individual shields for each phase conductor is not
allowed on any cable size for grid and generator cabling.
