Safety information

CAUTION
The 100 mm cooling clearances above and to the side of the components must be
observed.
Note
The connecting cables to the Motor Module must be kept as short as possible (max. 5 m).
CAUTION
The connections must not be interchanged:
• Incoming cable to the Motor Modules 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
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 Motor Module, 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 Motor Module, the 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.
