      Information

      Overview Manuals Common Applications Product Precautions
      Siemens 6SL3352-1AE37-5BA1 is a SINAMICS 745 A replacement power block for the V and W phases of a 380-480 V AC Drive/Power Module. It restores the two inverter phase sections within the matching drive power assembly.
      • Provides the V- and W-phase semiconductor power section of the specified AC Drive/Power Module
      • Carries the documented 745 A power path for the 380-480 V three-phase drive execution
      • Uses painted power assemblies for the identified replacement configuration
      • Uses nickel-plated busbars at the documented high-current interconnections

      6SL3352-1AE37-5BA1 is installed with matching SINAMICS AC Drive/Power Module chassis, documented V- and W-phase busbar positions, approved gate-drive and control connections, installed cooling and protective-conductor arrangement in the approved SINAMICS AC Drive/Power Module arrangement.

      Isolate and discharge the complete drive DC link before removing the 6SL3352-1AE37-5BA1 power block. Match the V/W phase position, busbar interfaces, control connectors and cooling path before controlled energization.

      Important Notice: Verify the complete 6SL3352-1AE37-5BA1 marking and the V/W phase assignment before dismantling the drive. Preserve the documented connections and complete the controlled commissioning checks before service.

      The first document consolidates the exact article record and engineering data. The second provides a separate installation, safety or commissioning reference for the identified hardware function.
      V/W phase-section restorationRestores the two named inverter phases without transferring identity from another power-block execution.
      Large motor-drive power maintenanceReturns a documented 745 A drive power path to service after controlled isolation and inspection.
      High-current drive cabinet refurbishmentSupports cabinet maintenance where the painted assembly and nickel-plated busbar execution must be preserved.
      Controlled power-module recommissioningProvides a defined sequence for insulation, connection and phase-output verification before motor operation.
      Before work, verify 6SL3352-1AE37-5BA1 against the installed SINAMICS AC Drive/Power Module power hardware and follow the applicable Siemens isolation and commissioning procedure.
      1Verify the complete 6SL3352-1AE37-5BA1 marking and the V/W phase assignment before dismantling the drive.
      2Isolate incoming three-phase power and prove the DC link discharged with the approved procedure.
      3Record every busbar, gate-drive, sensor, cooling and protective-conductor connection before removal.
      4Protect semiconductor assemblies from ESD and avoid mechanical loading of the control connectors.
      5Inspect nickel-plated busbar contact faces and retain the manufacturer-specified hardware arrangement.
      6Confirm the painted module execution and the 745 A, 380-480 V drive identity before installation.
      7Energize through the approved commissioning sequence and observe drive diagnostics before enabling the motor.
      8Verify V/W phase output behavior under controlled conditions before returning the machine to automatic service.
