General - Siemens SINAMICS G130 Operating Instructions Manual

General

Description
The dv/dt filter plus voltage peak limiter comprises two components: the dv/dt reactor and
the Voltage Peak Limiter, which cuts off the voltage peaks and returns the energy to the DC
link.
The dv/dt filters plus Voltage Peak Limiter must be used for motors for which the proof
voltage of the insulation system is unknown or insufficient.
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:
< 1000 V at U
< 1250 V at 660 V < U
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.
Risk of burns due to high surface temperature of the dv/dt reactor
The surface temperature of the dv/dt reactors may exceed 80° C. You can get seriously
burnt when touching the surface.
• Mount the dv/dt reactor so that it cannot be touched. If this is not possible, attach a
dV/dt filter plus Voltage Peak Limiter
