Siemens C98043-A7107-L4 L05 Power Interface Board
The printed-board designation for the SINAMICS DCM L05 power interface supplied under service article 6RY1803-0DB02.
Product Overview
C98043-A7107-L4 is the Siemens printed-board designation associated with the SINAMICS DCM power interface for option L05. For separate spare ordering, Siemens identifies the related service article as 6RY1803-0DB02.
Quotation and replacement should retain both numbers. The C98043 marking identifies the assembly itself, while the 6RY number controls the separately orderable spare.
Performance
- Provides the power-interface role defined by the option-L05 DCM hardware architecture.
- Participates in the converter measurement and thyristor-interface functions assigned to the board.
- Carries hardware-release information used for feature and service compatibility checks.

FAQ
Which spare article corresponds to C98043-A7107-L4?
Siemens lists 6RY1803-0DB02 as the separate-order spare for the option-L05 power interface.
Can C98043-A7107-L4 be ordered only from the printed code?
The code identifies the board, but the installed DCM article, L05 option and hardware release should also be supplied.
Why does the C98043-A7107-L4 hardware release matter?
Some DCM functions depend on the supported power-interface hardware generation, so the barcode label must be preserved.
Is C98043-A7107-L4 a complete SINAMICS DCM converter?
No. It is an internal power-interface board used in the matching option-L05 converter configuration.
What should be tested after fitting C98043-A7107-L4?
Complete connector, insulation, diagnostic and controlled converter-function checks under the applicable DCM procedure.
