6.4.2

Safety information

CAUTION
The cooling clearances of 100 mm above and below the components must be observed.
The dv/dt filters compact plus Voltage Peak Limiter must only be installed upright, to ensure
that cooling air flows from bottom to top through the heatsinks on the Voltage Peak Limiter.
Note
The motor cables between the Power Module or Motor Module and dv/dt filter compact, and
the cables to the DC link must be kept as short as possible (max. 5 m).
CAUTION
Terminals for order numbers 6SL3000-2DE41-4EA0, 6SL3000-2DG38-1EA0 and 6SL3000-
2DG41-3EA0
The terminals on the voltage limiting network (Voltage Peak Limiter) must always be
connected as follows:
• Cable from the DC link to the Motor Module at DCPS, DCNS and
• Cable to the dv/dt reactor 1U2, 1V2, 1W2.
Failure to connect the terminals correctly could damage the Voltage Peak Limiter.
CAUTION
When using dv/dt filters that SIEMENS has not approved for SINAMICS, then these dv/dt
filters can be thermally damaged.
The surface temperature of the dv/dt filters compact may exceed 80 °C.
CAUTION
If a dv/dt filter compact plus Voltage Peak Limiter is connected to the Power Module or
Motor Module, it must be activated during commissioning (p0230 = 2).
CAUTION
The maximum permissible output frequency when using dv/dt filters compact plus Voltage
Peak Limiter is 150 Hz.
