Application-Specific FAQ
Q: Can the 6SL3352-1AE41-4FA1 operate on a 480 V supply?
A: Yes. The ALM accepts 3-phase 380–480 V AC (±10%), making it compatible with both European 400 V and North American 480 V industrial supplies.
Q: Is a line reactor mandatory?
A: SIEMENS strongly recommends a matched line reactor to limit inrush current and protect the input rectifier bridge. Konmask can supply the correct reactor as part of a complete BOM.
Q: What Control Unit is compatible?
A: The CU320-2 DP (PROFIBUS) and CU320-2 PN (PROFINET) are the primary control units for S120 booksize configurations. The ALM connects via DRIVE-CLiQ.
Q: Can this module feed energy back to the grid?
A: Yes — this is the defining feature of an Active Line Module. Unlike a Basic Line Module, the ALM actively regenerates braking energy to the supply, reducing net energy consumption.
Q: What is the typical lead time?
A: In-stock units ship within 2–3 business days. For out-of-stock scenarios, lead time is 4–8 weeks depending on SIEMENS factory allocation.
