Temperature evaluation
The Line Harmonics Filter compact is forced cooled via fans. In the event of fan failure, the
integrated temperature sensors protect the Line Harmonics Filter compact against
overheating.
● The temperature sensor for triggering the warning level is interconnected to digital input
● The temperature sensor for triggering the fault threshold is interconnected to the line

dV/dt filter compact plus Voltage Peak Limiter (option L07)
Description
The dV/dt filter compact plus Voltage Peak Limiter comprises two components: the dV/dt
reactor and the voltage-limiting network (Voltage Peak Limiter), which cuts off the voltage
peaks and feeds back the energy into the DC link. The dV/dt filter compact plus Voltage
Peak Limiter is designed for use with motors for which the voltage strength of the insulation
system is unknown or insufficient.
The dV/dt filter compact plus Voltage Peak Limiter limits the voltage load on the motor
cables to values in accordance with the limit value curve A in compliance with IEC/TS
60034-25:2007.
The rate of voltage rise is limited to < 1600 V/µs, the peak voltages are limited to < 1400 V.
Restrictions
The following constraints should be noted when a dV/dt filter compact plus Voltage Peak
Limiter is used:
● The output frequency is limited to no more than 150 Hz.
● Maximum permissible motor cable lengths:

DI0 of the Control Unit. When the temperature sensor trips, "external alarm 1" (A7850) is
triggered.
contactor or circuit breaker via a contactor relay. When the temperature sensor trips, the
cabinet unit is shut down.
The signal from the temperature sensor is also interconnected to digital input DI1 of the
Control Unit. In this way, if the temperature sensor trips, "external fault 1" (F7860) is
triggered.
