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.
dv/dt filters compact plus Voltage Peak Limiters limit the voltage rate of rise dv/dt to values <
1600 V/µs - and the typical voltage peaks to the following values according to limit value
curve A acc. to IEC 60034-25:2007:
● < 1150 V at U
● < 1400 V at 660 V < U
Non-observance of the fundamental safety instructions and residual risks
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 through overheating due to insufficient ventilation clearances
Inadequate ventilation clearances can cause overheating with a risk for personnel through
smoke development and fire. Furthermore, an increased number of failures and shorter
service life of the components can occur.
• Ensure 100 mm ventilation clearances above and below the component.
• Always mount the dv/dt filters compact plus Voltage Peak Limiter in a vertical, upright
