General

Description
The dv/dt filter compact plus Voltage Peak Limiter comprises two components: the dv/dt
reactor and the voltage-limiting network (Voltage Peak Limiter), which cuts off the voltage
peaks and feeds back the energy 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 filter compact plus Voltage Peak Limiter limits the voltage load on the motor cables
to values in accordance with the limit value curve A in compliance with IEC/TS 60034-
25:2007.
The rate of voltage rise is limited to < 1600 V/µs, the peak voltages are limited to < 1400 V.
Danger to life if the fundamental safety instructions and remaining risks are not carefully
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.
• Adhere to the fundamental safety instructions.
• When assessing the risk, take into account residual risks.
Fire hazard due to overheating because of inadequate ventilation clearances
Inadequate ventilation clearances can cause overheating with a risk for personnel through
smoke development and fire. This can also result in increased failures and reduced service
lives of braking resistors.
• Maintain 100 mm ventilation clearances above and below the component.
• Always mount the dv/dt filters compact plus Voltage Peak Limiter in a vertical, upright
