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
