NOTICE
Damage to the Voltage Peak Limiter due to interchanged connections
Interchanging the connections on the Voltage Peak Limiter will cause damage to it.
• Connect the cable from the DC link of the Power Module to DCPS, DCNS.
• Connect the cable to the dV/dt reactor at 1U2, 1V2, 1W2.
NOTICE
Damage to the dV/dt filter 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 dV/dt filters that SIEMENS has approved for operation with SINAMICS.
NOTICE
Damage to the dV/dt filter by exceeding the maximum output frequency
The maximum permissible output frequency when using dV/dt filters plus Voltage Peak
Limiter is 150 Hz. The dV/dt filter may be damaged or destroyed if the output frequency is
exceeded.
• When commissioning you must always activate the dV/dt filter plus Voltage Peak Limiter
connected to the Power Module during commissioning (see SINAMICS S120/S150 List
Manual).
NOTICE
Damage to the dV/dt filter by exceeding the maximum pulse frequency
The maximum permissible pulse frequency on the Power Module is 4 kHz when a dV/dt
filter is used. The dV/dt filter may be damaged or destroyed if the pulse frequency is
exceeded.
• When using a dV/dt filter, do not operate a Power Module above the maximum pulse
frequency of 4 kHz.
NOTICE
Damage to the dV/dt filter if motor is not connected
If the drive is operated without the motor being connected, the dV/dt filter plus the Voltage
Peak Limiter may be damaged or destroyed.
• Never operate drives with dV/dt filters plus Voltage Peak Limiter without a motor being
connected.
Note
Keep the connecting cables to the Power Module as short as possible (max. 5 m).
