      It is identified as an inverter thyristor trigger board for a PowerFlex 755 75 kW frequency-converter application and retains the paired PN-173122 and PN-173123 service identity.
      • Preserves the paired PN-173122 and PN-173123 service identity
      • Supports the documented PowerFlex 755 75 kW application
      • Provides the inverter power-stage thyristor trigger function
      • Requires controlled board replacement and post-service verification

      PN-173122-PN-173123 operates with the documented PowerFlex 755 75 kW host drive, the assigned internal board position, the matched keyed connectors and cable routing, the associated inverter power-stage devices.

      Engineered applications include PowerFlex 755 75 kW service, Paired board replacement, Power-stage trigger restoration, Post-repair drive commissioning.

      Important Notice: Match both PN-173122 and PN-173123 markings to the installed PowerFlex 755 75 kW hardware record. Isolate all drive power, prove the DC bus is at zero, preserve connector routing and complete controlled diagnostics before service release.

      The first document presents exact-model technical and engineering data. The second provides a separate installation, connection, commissioning and acceptance workflow.

      PowerFlex 755 75 kW service
      Restores the documented trigger-board position in the specified drive application.
      Paired board replacement
      Maintains both PN-173122 and PN-173123 identities in the controlled service record.
      Power-stage trigger restoration
      Re-establishes the documented thyristor trigger path after a verified board fault.
      Post-repair drive commissioning
      Confirms connectors, diagnostics and controlled drive response before release.
      Read the applicable Allen-Bradley instructions before work. Verify PN-173122-PN-173123, the installed system and every configured interface before isolation, wiring or commissioning.
      1
      Verify the complete PN-173122-PN-173123 identity and the assigned PowerFlex 755 75 kW board position before work.
      2
      Stop the drive, isolate every power source and follow the documented lockout procedure before opening the cabinet.
      3
      Wait the documented discharge period and measure the DC bus at the specified test points; proceed only after it reads zero.
      4
      Use grounded ESD controls and handle PN-173122-PN-173123 only by protected board edges.
      5
      Record every connector, cable label, board orientation and adjacent component relationship before disconnection.
      6
      Compare both replacement identifiers and the installed drive hardware record; do not substitute a single unmatched board reference.
      7
      Seat each keyed connector without force and restore the recorded cable routing, shielding and grounding arrangement.
      8
      Re-energize through the approved sequence, review drive diagnostics and prove controlled power-stage response before release.

      Technical notes

      Install PN-173122-PN-173123 only in the documented PowerFlex 755 75 kW board position. Isolate all drive power, prove the DC bus is at zero, preserve connector routing and complete controlled diagnostics before service release.

      FAQS

      • Which identifiers must match for Allen-Bradley PN-173122-PN-173123?
        The exact-model source presents PN-173122 and PN-173123 together. Match both identifiers to the installed service record and board position before replacement.
      • Which drive application is documented for Allen-Bradley PN-173122-PN-173123?
        The authorized exact-model record identifies a PowerFlex 755 frequency-converter application rated at 75 kW.
      • What function is assigned to Allen-Bradley PN-173122-PN-173123?
        It is identified as an inverter thyristor trigger board that supports the drive power-stage trigger path.
      • Can Allen-Bradley PN-173122-PN-173123 be replaced by matching only one of the two PN markings?
        No uncontrolled substitution is supported. Preserve the paired PN-173122 and PN-173123 identity and compare the complete installed hardware record before installation.
      • What must be recorded before disconnecting Allen-Bradley PN-173122-PN-173123?
        Record the board position, orientation, every keyed connector, cable label, routing and the relationship to adjacent power-stage components.
      • What stored-energy test is required before servicing Allen-Bradley PN-173122-PN-173123?
        After isolating the drive, follow the Rockwell discharge procedure and measure the DC bus at the designated test points; voltage must be zero before service.
      • How should technicians protect Allen-Bradley PN-173122-PN-173123 from electrostatic damage?
        Use grounded ESD controls, protect every connector and contact, and handle the circuit board only by its edges.
      • What acceptance checks follow installation of Allen-Bradley PN-173122-PN-173123?
        Verify connector seating and routing, review PowerFlex 755 diagnostics, then perform a controlled start and confirm the intended power-stage response without active faults.
