The stated current rating indicates the maximum continuous current the filter can safely manage without overheating. It is crucial to select a filter with a sufficient current margin for your specific application to ensure reliable operation and prevent premature component failure. Always consult the power module's requirements.

The 380V-480V range covers the typical industrial voltage levels found in many regions globally. Proper verification of the incoming supply voltage is a prerequisite for safe and effective installation of this filter with its corresponding SINAMICS power module.

What is the significance of the "FSC Footprint" for this product?

The "FSC Footprint" refers to a standardized mounting and interconnection design for Siemens SINAMICS components. This means the 6SL3203-0BE23-8BA0 is engineered to physically and electrically interface seamlessly with SINAMICS power modules that share this specific footprint. It ensures a compact, space-saving installation within control cabinets.

Utilizing the FSC footprint simplifies the assembly process and reduces the overall footprint of the drive system. Components are designed for direct mounting, often stacking or side-by-side, which minimizes wiring complexity and potential connection errors. This standardization is key for efficient panel building.

This compatibility ensures that the filter is an integral part of the SINAMICS ecosystem, designed for optimal performance alongside the power modules. It guarantees proper physical alignment and electrical connection points, contributing to a robust and reliable drive solution.

Can this filter be used with SINAMICS G120 or S120 drives?

The Siemens 6SL3203-0BE23-8BA0 is specifically designed for SINAMICS power modules that utilize the FSC (Foot Module Standard Compact) footprint. While the G120 and S120 families have various power module options, this particular filter is intended for those modules explicitly featuring the FSC interface. Users must verify their specific power module's compatibility.

The designation "FSC Footprint" is critical here. Some SINAMICS G120 or S120 power modules might use different physical footprints or interconnection methods. Therefore, direct compatibility should always be confirmed by cross-referencing the filter's product number with the specifications of the intended SINAMICS drive system.

In essence, if the SINAMICS power module in your G120 or S120 system has the FSC footprint, this filter is likely compatible. If it uses a different footprint (e.g., specific frame sizes or connection types), a different filter model would be required. Always consult the product manuals.

What are the environmental operating conditions for this line filter?

The Siemens 6SL3203-0BE23-8BA0 is designed for operation in industrial environments with an ambient temperature range of -25°C to +55°C. It also has a housing protection rating of IP20, meaning it is protected against solid objects greater than 12.5mm but not against water ingress. Ensure adequate ventilation within the control cabinet.

The specified temperature range allows for flexible installation across various climates and industrial settings. However, it's crucial to ensure that the ambient temperature within the control cabinet, considering heat generated by other components, remains within these operational limits for optimal filter performance and longevity.

The IP20 rating signifies that the filter requires installation within an enclosure to protect it from dust, mechanical damage, and accidental contact. It is not suitable for direct exposure to moisture or harsh environmental conditions without additional protective measures.

How is the 6SL3203-0BE23-8BA0 installed and wired?

Installation involves mounting the filter directly onto the designated mounting points, typically below or adjacent to the SINAMICS power module, utilizing the FSC footprint. Wiring requires connecting the incoming 3-phase AC power lines (L1, L2, L3) to the filter's input terminals. The filter's output terminals are then connected to the corresponding input terminals of the SINAMICS power module.

Proper grounding of both the filter and the power module to the enclosure's earth ground is mandatory for safety and effective EMC performance. Ensure all connections are secure and torqued to the manufacturer's specifications. Refer to the specific SINAMICS system manual for detailed wiring diagrams and installation procedures.

This filter is a passive component and does not require any configuration or programming. Its function is purely electrical, based on its physical connections. Ensure the power supply is de-energized before commencing any wiring or installation work.
