dv/dt filter compact plus Voltage Peak Limiter
6.2.4.1
Description
The dV/dt filter compact plus Voltage Peak Limiter has two components: The dV/dt reactor
and the voltage limiting network (Voltage Peak Limiter). The voltage limiting network cuts-off
the voltage peaks and feeds the energy back into the DC link.
The dV/dt filter compact plus Voltage Peak Limiter is designed for use with motors for which
the voltage strength of the insulation system is unknown or insufficient.
The dV/dt filters compact plus Voltage Peak Limiter limit the voltage load on the motor
cables to values which correspond to limit value curve A according to IEC/TS 60034-
25:2007.
The rate of voltage rise is limited to < 1,600 V/µs, the peak voltages are limited to < 1400 V.

Safety instructions for du/dt filter compact plus Voltage Peak Limiter
Danger to life if the fundamental safety instructions and residual risks are not observed
The non-observance of the fundamental safety instructions and residual risks stated in
Chapter 1 can result in accidents with severe injuries or death.
• Observe the fundamental safety instructions.
• Consider the residual risks for the risk evaluation.
Danger to life due to electric shock in the event of missing touch protection
Death or serious injury can result when live parts are touched.
• For the dV/dt filters compact plus Voltage Peak Limiter, use touch protection according
Danger of fire through overheating for insufficient ventilation clearances
Inadequate ventilation clearances can cause overheating with a risk for personnel as a
result of fire and smoke. Furthermore, an increased number of failures and shorter service
life of the components can occur.
• Maintain 100 mm clearances above and below the components.
• Always mount the dV/dt filters compact plus Voltage Peak Limiter in a vertical, upright
