General - Siemens Sinamics G120P Operating Instructions Manual

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.
