4.4.4 Connection example EDS standard system with FTC4…XET
See the next page for this example.
Key for connection example:
Ensure that all live conductors are routed through the
measuring current transformer. Do not route any PE
conductors or shields of shielded conductors through the
measuring current transformer! Commercial measuring
current transformers are not suitable for EDS460/461 or
EDS490/491 systems and must not be used.
Only if these notes are observed will you obtain a true
measurement result.
Additional information is available in our "Transformer
installation" technical information.
