CAUTION
Risk of burns resulting from high surface temperature of the dV/dt filter compact
The surface temperatures of dV/dt filters compact may exceed 80° C. You can be severely
burnt when touching the surface.
• Mount the dV/dt filters so that they cannot be touched. If this is not possible, at the
dangerous locations, attach an appropriate warning note that is clearly visible and easy
to understand.
NOTICE
Damage to the dV/dt filter compact by using components that have not been released
When using components that have not been released, damage or malfunctions can occur
at the devices or the system itself.
• Only use a dV/dt filter compact that SIEMENS has released for SINAMICS.
NOTICE
Risk of damaging the dV/dt filter compact by exceeding the maximum output frequency
The maximum permissible output frequency when using dV/dt filters compact plus Voltage
Peak Limiter is 150 Hz. The dV/dt filter compact can be damaged if the output frequency is
exceeded.
• When commissioning you must always activate the dV/dt filter compact plus Voltage
Peak Limiter connected to the Power Module during commissioning (see SINAMICS
S120/S150 List Manual).
NOTICE
Damage to the dV/dt filter compact by exceeding the maximum pulse frequency
The maximum permissible pulse frequency on the Power Module is 4 kHz. The dV/dt filter
compact can be damaged if the pulse frequency is exceeded.
• When using a dV/dt filter compact, operate a Power Module with a maximum pulse
frequency of 4 kHz.
NOTICE
Damage to the dV/dt filter at an output frequency less than 10 Hz in continuous operation
Continuous operation at an output frequency less than 10 Hz can produce thermal overload
and destroy the dV/dt filter.
• Do not load the dV/dt filter for more than five minutes at an output frequency less than
10 Hz.
• Then subsequently select operation at an output frequency > 10 Hz for a duration of
five minutes.
