Siemens 6SE7041-8HK85-1HA0 Rectifier Interface Module
A PER2 interface spare for higher-voltage H- and K-design infeed and regenerative supply units.
Key Information
6SE7041-8HK85-1HA0 is the PER2 rectifier-interface module for designated SIMOVERT MASTERDRIVES infeed and regenerative feedback units. Its ordering code belongs to the higher-voltage host family and must not be confused with the EK version.
The module is an internal spare, not a standalone converter. Safe replacement depends on the host supply unit, its power section and the installed hardware execution.
Functions
- Implements the specified interface between control electronics and the rectifier section.
- Supports matching infeed or energy-feedback operation in H- and K-design hardware.
- Maintains the correct board execution for service of a legacy high-voltage MASTERDRIVES unit.

Installation
- Verify the HK article family and the complete host-unit label before opening the converter.
- Apply high-voltage isolation, DC-link discharge and ESD controls throughout the board exchange.
- Photograph and label connectors so the interface wiring returns to its original positions.
- Complete diagnostic, charging, infeed and regenerative tests under the approved service procedure.
Lifecycle
- Maintain a tested spare strategy for critical legacy high-voltage installations.
- Link the replacement board serial identity to the host-unit service history.
- Evaluate LV SINAMICS migration with the complete system data before spare availability becomes critical.
FAQ
Can 6SE7041-8HK85-1HA0 replace 6SE7041-8EK85-1HA0?
No direct replacement should be made; the HK and EK codes identify different supply-voltage families.
Why is the host nameplate essential for 6SE7041-8HK85-1HA0?
It confirms voltage range, mechanical design, regenerative configuration and hardware execution before the cabinet is disturbed.
Is 6SE7041-8HK85-1HA0 still an active Siemens product?
The official lifecycle record shows cancellation, so availability and migration planning should be handled as legacy support.
What evidence should accompany a 6SE7041-8HK85-1HA0 enquiry?
Send the supply-unit article, serial and version labels, the existing PER2 label, fault history and clear connector photographs.
Which checks follow 6SE7041-8HK85-1HA0 installation?
Verify connector seating, internal diagnostics, charge sequence, DC-link stability, enable logic and regenerative feedback behavior.
Can 6SE7041-8HK85-1HA0 be repaired by general panel personnel?
The exchange is inside high-energy converter equipment and requires qualified drive-service procedures and controlled testing.
