General

Description

The du/dt filter plus voltage peak limiter comprises two components: the du/dt reactor and

the Voltage Peak Limiter, which cuts off the voltage peaks and returns the energy to the DC

link.

The du/dt filters plus Voltage Peak Limiter must be used for motors for which the proof

voltage of the insulation system is unknown or insufficient.

du/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 < 1000 V at U

NOTICE

Maintain ventilation clearances

The 100 mm clearances above and below the components must be observed.

NOTICE

Do not interchange the I/Os

The terminals on the voltage limiting network (Voltage Peak Limiter) must always be

connected as follows:

• Cable from the DC link of the Power Module at DCP, DCN and

• Cable to the du/dt reactor 1U2, 1V2, 1W2.

Failure to connect the terminals correctly could damage the voltage peak limiter.
