dv/dt filter plus Voltage Peak Limiter

6.2.3.1

Description

The dV/dt filter plus Voltage Peak Limiter consists of two components: the dV/dt reactor and
the voltage limiting network (Voltage Peak Limiter), which limits voltage peaks and returns
the energy to the DC link.
The dV/dt filters with Voltage Peak Limiter must be used for motors for which the proof
voltage of the insulation system is unknown or insufficient. Standard motors of the 1LA5,
1LA6 and 1LA8 series only require them at supply voltages > 500 V +10 %.
dV/dt filters plus Voltage Peak Limiters limit the rate of voltage rise to values < 500 V/µs and
the typical voltage peaks with rated line voltages to the values below (with motor cable
lengths less than 150 m):
< 1000 V at V
Components
The order numbers of the individual components (dV/dt reactor and Voltage Peak Limiter)
are listed in the following table:

Safety instructions for du/dt filter 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 filter plus Voltage Peak Limiter, use touch protection according to IPXXA
