Features:
- The -1JA1 suffix completes the 6SE7031-7HG84 order identity.
- Chassis designs E through H define the documented mechanical range.
- AC and DC source families use separate voltage-selection bands.
Confirm the complete suffix before comparing the PSU1 with an installed chassis.
Start the selection check with the E–H design, then identify whether the incoming source is AC or DC.
Use G25 and X9 as chassis references only after the source family and voltage band agree.
The Siemens 6SE7031-7HG84-1JA1 PSU1 Power Supply Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Source Matching Logic
- First decision: Identify whether the chassis receives three-phase AC or DC before comparing a voltage band.
- AC path: Frequency belongs to the three-phase source check and is not applied to a DC-fed chassis.
- DC path: Matching follows the documented DC window without borrowing the AC classification.
- Final check: Source type, voltage family and E–H chassis design must agree for 6SE7031-7HG84-1JA1.
PSU1 Positioning
- Mechanical scope: Designs E through H establish the chassis range for the PSU1 assignment.
- Component reference: G25 identifies where the PSU1 sits within that chassis structure.
- Functional boundary: The G25 position separates the power-supply assembly from control and monitoring positions.
- Use rule: Confirm the chassis design before treating G25 as the 6SE7031-7HG84-1JA1 location.
Terminal-Strip Context
- E–H function: X9 is the terminal-strip reference associated with PSU1 in this chassis range.
- Label reuse: The same X9 designation serves different power assemblies in other chassis designs.
- Trace sequence: Read the chassis design first, then follow X9 to the assigned assembly.
- Error boundary: An X9 label alone does not prove that the connected unit is 6SE7031-7HG84-1JA1.
Complete-Code Check
- Base number: 6SE7031-7HG84 does not identify the complete ordered variant.
- Suffix role: The -1JA1 ending completes the product identity used on the page.
- Electrical confirmation: Supply-class agreement supports the match but does not replace the full code.
- Selection boundary: Use the complete number together with chassis design and source type.
