Its exact installed duty must be reconstructed from the complete converter type, 6RA24 schematic, power-section drawing, and physical component label before connection or substitution.
Important Notice: Use the complete 6QN5501-0BA code and verify the physical nameplate and current Siemens documentation before installation or replacement.

Important Notice: These are two separate Apter Power documents prepared from the manufacturer-published Siemens information named in each document. Confirm the physical nameplate, current Siemens documents, and host-system requirements before installation or replacement.
DC drive power sections
Maintain a documented 6RA24 converter assembly.
Parallel power units
Preserve the control and monitoring path between power sections.
Legacy drive audits
Trace the exact component before a high-energy replacement.
Read and follow the exact Siemens documentation and host-equipment instructions before use. Verify 6QN5501-0BA from the physical nameplate.
1
Apply lockout and verify DC-link absence of voltage
2
Use the complete 6RA24 power-section drawing
3
Record every thyristor gate/cathode and monitoring lead
4
Verify fan and fuse-monitoring contact behavior
5
Do not infer converter rating from 6QN5501-0BA alone
