Siemens 6SE7041-8EK85-0LA0 FBG Power Interface Board
An internal FBG power-interface assembly for designated EH-design SIMOVERT MASTERDRIVES infeed units.
Key Information
6SE7041-8EK85-0LA0 is an FBG power-interface board used in selected SIMOVERT MASTERDRIVES rectifier and regenerative-feedback units. It belongs to the exact EH host execution and must remain linked to the complete infeed-unit article.
The final -0LA0 hardware identity is essential. Nearby 6SE70 board references can share the FBG designation while serving different voltage classes, host designs or connector arrangements.
Functions
- Provides the internal power-interface function between the matching infeed power section and its control electronics.
- Maintains the specified FBG hardware execution during service of an established MASTERDRIVES cabinet.
- Supports the monitoring and control paths defined by the compatible rectifier or regenerative host unit.

Installation
- Record the host-unit nameplate, both board faces and every connector position before removal.
- Isolate all supplies, prove DC-link discharge and use ESD controls approved for drive electronics.
- Compare the complete -0LA0 label with the removed board; do not select by the FBG description alone.
- After installation, verify precharge, infeed diagnostics, DC-link response and regenerative operation where fitted.
Lifecycle
- Keep the board label and host-unit article together in the asset record.
- Store tested spares in dry, ESD-controlled packaging.
- Assess modernization at complete drive-system level rather than treating the board as a universal replacement.
FAQ
Which host units are documented for 6SE7041-8EK85-0LA0?
The known host references are the listed EH-design 6SE7041 and 6SE7042 infeed units; the complete nameplate must still be checked.
Can 6SE7041-8EK85-0LA0 replace an FBG board with another suffix?
Not automatically. The suffix identifies a hardware execution, and host design, connectors and electrical class must all agree.
What evidence is needed before ordering 6SE7041-8EK85-0LA0?
Provide the infeed-unit nameplate, front and rear board labels, connector photographs, cabinet position and fault history.
Is 6SE7041-8EK85-0LA0 a complete converter?
No. It is an internal power-interface board and depends on the correct MASTERDRIVES infeed power section.
What should be tested after fitting 6SE7041-8EK85-0LA0?
Use the approved service sequence to check precharge, DC-link stability, diagnostics, enable paths and regenerative behavior.
