ABB NU8976A99 | Exact Part Identity & Compliance Spare

Description

• Model & Brand: ABB NU8976A99
• Related Identification: HIER466665R0099 / HIEE320693R0001
• Part Type: Industrial control / function board; the exact functional designation should be confirmed against the physical ABB nameplate and system documentation.
• System Association: Third-party records associate the identifiers with ABB industrial control equipment, but available descriptions conflict on the exact application.
• Physical Dimensions: Approximately 380 × 320 × 40 mm is reported by one supplier for NU8976A / HIEE320693R0001; verify against the actual revision before cabinet or freight planning.
• Estimated Shipping Weight: Approximately 0.6 kg net according to one supplier listing; use the actual packed weight for freight documentation.
• What’s in the Box: NU8976A99 / HIER466665R0099 / HIEE320693R0001 module only unless the purchase order specifically includes mounting hardware, connectors, cables, or documentation.
• Physical Inspection Points: Check the PCB surface, edge connectors, mounting holes, retaining hardware, identification label, and any daughterboard or interface connectors.

Product Introduction

Legacy ABB control hardware requires strict part-number control because several identifiers may appear on the same physical assembly. NU8976A99, HIER466665R0099, and HIEE320693R0001 are presented by multiple suppliers as associated identifiers, while other listings give conflicting functional descriptions. The nameplate should therefore be treated as the primary identity record—not a marketplace title.

The available technical evidence also points to a function-board/control-module category, but the exact host architecture is not sufficiently established from authoritative ABB documentation located for this part. One technical listing identifies NU8976A / HIEE320693R0001 as a driver module, while another describes the same identifiers as an ABB control/processor module. That discrepancy matters during substitution (especially for legacy systems where connector pinouts and revision compatibility can differ).

Core Technical Specifications

ABB NU8976A99

The 380 × 320 × 40 mm dimension and 0.6 kg weight originate from a supplier listing and should be treated as logistics estimates rather than controlled engineering specifications.

Global Compliance & Industry Certifications

For this ABB legacy control assembly, certification should be established from the actual product documentation and host-system configuration.

• CE Mark: Verify the applicable ABB Declaration of Conformity for the complete equipment.
• UL/cUL: Confirm whether the exact assembly and installation configuration are covered by the applicable North American certification.
• ATEX/IECEx: Do not infer hazardous-area approval from the ABB model number. Certification must explicitly cover the equipment and intended installation.
• Marine Approvals: DNV or equivalent certification should only be stated when supported by documentation for the exact assembly.
• Electrical Safety: Evaluate compliance at the complete control-system level where the module is installed as an internal component.

Keep the nameplate photograph, serial number, revision, COO documentation, and applicable conformity records with the asset file.

Verify specific lot certifications with OEM.

Long-Term Storage & Asset Preservation Guide

1. Keep the board in an ESD shielding bag. Protect the edge connector and exposed PCB surfaces from static discharge, dust, and accidental contact with conductive shelving.
2. Control warehouse humidity. A target below 60% RH is appropriate for long-term electronic storage where practical. Avoid condensation when moving the module from a cool warehouse into a warmer electrical room.
3. Preserve revision traceability. Record the complete NU8976A99 / HIER466665R0099 / HIEE320693R0001 identification, serial number, and date code before storage. Do not place units with different revisions into one unsegregated inventory bin (this is a common source of incorrect legacy substitutions).

Physical Installation Prerequisites

• Verify the exact ABB host system before installation.
• Match the complete part number and hardware revision against the equipment BOM.
• Confirm the mating connector or backplane before insertion.
• Do not use the reported 380 × 320 × 40 mm dimensions for cabinet design without checking the actual mechanical drawing.
• Maintain sufficient cabinet airflow around the installed board; where no OEM clearance is available, 50 mm above and below can be used as an initial planning allowance, subject to the final cabinet drawing.
• Verify protective grounding and cabinet bonding requirements.
• Inspect connector pins, mounting holes, retaining hardware, and PCB surfaces before installation.
• Use a grounded ESD wrist strap and ESD-safe workstation.
• Never force the module into its mating connector. Misalignment can damage both the board and backplane.

Buyer’s FAQ

Q: What HS tariff code should be used for ?

The HS classification should follow the confirmed technical function of the actual assembly. Available supplier descriptions conflict, so assigning a code solely from would create unnecessary customs risk. Confirm the classification with the customs broker using the technical description and destination-country tariff schedule.

Q: What COO should be declared?

One supplier identifies Sweden as the country of origin for HIER466665R0099 / , but COO must be supported by the documentation for the actual shipment. Do not infer COO from the seller’s shipping location.

Q: Should this module be insured during international transportation?

For a hard-to-source legacy ABB spare, cargo insurance is appropriate when the replacement value warrants it. Photograph the module, identification label, ESD packaging, outer carton, and final sealed package before dispatch.

Q: Does the module contain the latest firmware?

Do not assume that it does. Available sources identify this hardware inconsistently, and firmware compatibility depends on the actual ABB host system and hardware revision. Verify the installed revision and required firmware/configuration before commissioning.

Asset-control recommendation: Record / / as one controlled identity set only after reconciling the physical nameplate with the host-system BOM. The available market data contains conflicting functional descriptions, so dimensions, electrical ratings, firmware, customs classification, and substitution claims should remain marked “verify by exact revision” until OEM documentation or physical inspection establishes the definitive configuration.
