Safety information

NOTICE
Maintain ventilation clearances
The ventilation clearances of 100 mm above and below the components must be observed.
Note
Cable lengths
The connecting cables to the Motor Module must be kept as short as possible (max. 5 m).
NOTICE
Do not interchange the I/Os
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 reactors may exceed 80° C.
NOTICE
Activation during commissioning
If a dV/dt filter plus voltage peak limiter is connected to the Motor Module, it is essential that
it is activated during commissioning (p0230 = 2).
NOTICE
No operation without connected motor
When a dV/dt filter plus voltage peak limiter is used, the drive must not be operated without
a connected motor, otherwise the filter can be destroyed.
