Technical data
12.1.4 Inverter < 10 Hz
For systems involving extremely low-frequency control in the range of up to 0.1...460 Hz and very
slow and continuously changing extraneous DC voltages due to dynamic load conditions in an IT
system, continuous insulation monitoring can be optimised using this profile.
