Safety information

NOTICE
Maintain ventilation clearances
The ventilation 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
Cable lengths
The motor cables between the Motor Module and dV/dt filter compact, and the cables to the
DC link must be kept as short as possible (max. 5 m).
NOTICE
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.
NOTICE
Use only approved dV/dt filters
When using dV/dt filters that SIEMENS has not approved for SINAMICS, then these dV/dt
filters can be thermally damaged.
Hot surfaces
The surface temperature of the dV/dt filters compact may exceed 80° C.
NOTICE
Activation during commissioning
If a dV/dt filter compact plus voltage peak limiter is connected to the Motor Module, it is
essential that it is activated during commissioning (p0230 = 2).
