1.2.5 Connection of converters to grounded systems (TN or TT)
On SINAMICS units connected to grounded TN or TT systems, it is basically possible to connect a ground fault
monitor capable of early detection of high-impedance ground faults (universal-AC/DC-sensitive differential current
monitor or Residual Current Monitor RCM) to the converter input. However, this ground fault monitor is relatively
complicated to install owing to the need for a summation current transformer in the mains feeder cable. Furthermore,
the response threshold of the monitor must be adjusted according to the relevant plant conditions. This means, for
example, on drives with long shielded motor cables in the power range of the SINAMICS converters described in this
engineering manual, the response thresholds of 30 mA or 300 m which would be required to ensure personnel safety
and fire protection are not technically feasible (see also section "Line filters", subsection "Magnitude of leakage or
interference currents"). For this reason, it is not normal practice to use a ground fault monitor in the power range of
the SINAMICS converters described in this manual. However, as described above, suitable protection must be
provided on the line side to ensure that the substantial ground fault current caused by a low-impedance ground fault
or short circuit in the device is promptly interrupted.
