Siemens 6RY1803-0CM20 Coated Power Interface
A Siemens spare-part article for the coated power-interface board identified as C98043-A7109-L100.
Overview
6RY1803-0CM20 is the Siemens article number for a coated power-interface spare used in the SIMOREG DC drive platform. The associated board identifier provides a second identity check during service.
This is an internal drive assembly rather than a complete converter. Replacement should be carried out against the cabinet documentation, connector arrangement and installed hardware revision.

FAQ
Which board code should be checked with 6RY1803-0CM20?
Compare the installed assembly with C98043-A7109-L100 and confirm that both identifiers refer to the same coated execution.
Is 6RY1803-0CM20 a complete SIMOREG converter?
No. It is a service component inside the drive system, so the host converter and section position must be identified.
What photographs reduce mismatch risk for 6RY1803-0CM20?
Capture the article label, PCB number, coating designation, every connector, jumper position and the surrounding cabinet assembly.
Can an uncoated interface replace 6RY1803-0CM20?
Do not make that substitution without Siemens documentation and an environmental or revision review for the installed cabinet.
What checks follow installation of 6RY1803-0CM20?
Inspect seating and clearances, confirm connector positions, restore power using the drive procedure and complete diagnostics plus a controlled functional test.
What should accompany a quotation for 6RY1803-0CM20?
Provide both identity codes, host drive nameplate, hardware revision, fault evidence, quantity and clear board photographs.
