If the device is provided with earth fault detection in a non-earthed system, also the
components of the earth fault current (active and reactive components) are indicated.
In addition to those measured values listed in the table, it is possible to retrieve user
defined measurement, metering and set points, if these were generated during the
configuration of the device according to Section 5.2 and/or 5.3 "Generating user de-
finable functions with CFC".
