Safety information

CAUTION
The cooling clearances of 100 mm above and below the components must be observed.
Note
The connecting cables to the Power Modules or Motor Modules must be kept as short as
possible (max. 5 m).
CAUTION
The connections must not be interchanged:
• Incoming cable from the Power Modules or Motor Modules to 1U1, 1V1, 1W1, and
• Outgoing cable to the load 1U2, 1V2, 1W2.
Non-observance may damage the sine-wave filter.
CAUTION
If sine-wave filters are used that have not been approved for SINAMICS by SIEMENS, the
Power Modules or Motor Modules may be damaged or may malfunction.
The surface temperature of the sine-wave filters can exceed 80°C.
CAUTION
If a sine-wave filter is connected to the Power Modules or Motor Modules, the converter
must be activated during commissioning (p0230 = 3) to prevent the filter from being
destroyed.
If a sine-wave filter is connected to the Power Module or Motor Module, the Power Module
or Motor Module must not be operated without a connected motor because otherwise the
filter can be destroyed.
CAUTION
The maximum permissible output frequency when sine-wave filters are used is 150 Hz.
Sine-wave filters discharge a high leakage current to the protective ground conductor.
Due to the high leakage current associated with sine-wave filters, they or the relevant
control cabinet must be permanently connected to PE.
According to EN 61800-5-1, Section. 6.3.6.7, the minimum cross-section of the protective
ground conductor must conform to the local safety regulations for protective ground
conductors for equipment with a high leakage current.
