Siemens C98043-A7010-L2 SIMOREG DC-MASTER Field-Supply Power-Section Board
The L2 execution of the SIMOREG DC-MASTER field-supply power section for the documented 30 A device class.
Key Information
C98043-A7010-L2 is the L2 execution of the C98043-A7010 field-supply power-section board used in the 15 A and 30 A SIMOREG DC-MASTER device range.
Siemens assigns the L2 board to the 30 A armature-current and 5 A field-current execution. The board carries field power wiring and snubber functions, gate-pulse transformers, field-current sensing and field-line-voltage measurement.
The L number is a compatibility boundary. A replacement record should preserve the complete board label and the host 6RA70 order number.
Functions
Drive the field power section
Provides the documented power and trigger path for the field supply.
Measure field current
Uses the board sensing path required by the field-current control system.
Synchronize field gating
Derives the field-gating synchronization from the measured field line voltage.
Maintain protection evidence
Retains snubber, fuse-monitoring and board-identity information within the host unit record.

Installation
De-energize
Isolate all 6RA70 inputs, outputs and electronic power supplies before opening the unit.
Capture
Photograph the board label, host MLFB, connectors and conductor positions.
Replace
Match the C98043-A7010-L2 identity before transferring connections.
Adjust
After field-board exchange, perform the documented field-current offset calibration and controlled startup.
Lifecycle
- L-number control
- The replacement board number must match through L2; an execution-state suffix after that boundary is handled separately.
- Calibration record
- Retain the field-current offset adjustment result with the service order.
- Host traceability
- Keep the 6RA70 order and serial details with the board identity.

FAQ
What host data should accompany a C98043-A7010-L2 quotation?
Provide the complete 6RA70 MLFB, serial number, board label, connector photographs and requested quantity.
Can C98043-A7010-L1 replace C98043-A7010-L2?
No. Siemens assigns L1 and L2 to different device and field-current classes, so the L number must match.
What service step follows a C98043-A7010-L2 exchange?
Siemens requires the documented field-current offset calibration after replacing an A7010 field board.
Why is the full C98043-A7010-L2 label important?
It preserves the board family and L2 compatibility boundary instead of reducing selection to the A7010 base number.
What safety condition applies before handling C98043-A7010-L2?
All inputs, outputs and the electronics supply of the 6RA70 must be voltage-free under the approved procedure.
