IT (ungrounded) systems
Don’t use EMC filters.
The screen winding of dedicated transformers must be grounded.
For installation without low voltage switch (e.g. contactor, air-circuit-breaker) use
overvoltage protection.
The voltage shift of the isolated supply must not be larger than the voltage shift in
case on an earth fault.
