Product Introduction

ABB S-073N 3BHB009884R0021 is an ACS6000 series phase module used in ABB medium-voltage AC drive systems. The module functions as a power conversion section component, handling phase power processing inside the drive topology for large motor control applications.

This module is typically replaced during ACS6000 drive maintenance when a power stage component failure occurs. Before installation, confirm the exact drive rating, phase position, hardware revision, and commissioning parameters because ACS6000 power modules are application-specific.

Installation & Configuration Guide

Stage 1: Pre-Installation Preparation (Approx. 30–60 minutes)

⚠️ Safety First

1. Notify operations of the planned MV drive shutdown.
2. Stop the motor using the approved operating procedure.
3. Open the upstream isolation device.
4. Apply lockout/tagout procedures.
5. Verify DC bus discharge according to ABB safety instructions.
6. Measure for absence of hazardous voltage before accessing the power section.

Tools Required

• ESD wrist strap
• Insulated hand tools
• Torque wrench
• Multimeter rated for the system voltage
• Wire labels
• Smartphone/camera for documentation

Data Backup

1. Save existing parameter files.
2. Record:
   • Drive type code
   • Firmware version
   • Fault history
   • Module position identification
3. Photograph:
   • Power connections
   • Fiber/control connections
   • Module mounting arrangement

Stage 2: Removing the Old Module (Approx. 45 minutes)

1. Remove required cabinet covers.
2. Confirm the DC link is fully discharged.
3. Label all electrical and fiber connections.
4. Disconnect:
   • Power connections
   • Control wiring
   • Fiber communication links
5. Remove mechanical fasteners.
6. Extract the phase module carefully using approved lifting/support methods.

⚠️ Inspection Point

Check:

• Busbar contact surfaces
• Connector condition
• Fiber optic cleanliness
• Signs of overheating or arcing

Keep the removed module for comparison until commissioning is complete.

Stage 3: Installing the New Module (Approx. 45 minutes)

1. Wear ESD protection before handling the module.
2. Verify:
   • ABB S-073N
   • 3BHB009884R0021
   • Correct position
3. Inspect module connectors before insertion.
4. Install the module into the correct mechanical position.
5. Tighten fasteners according to ABB torque requirements.
6. Reconnect:
   • Power connections
   • Control connectors
   • Fiber links

Self Checklist

• Correct phase module installed
• Fiber connectors clean and locked
• Power connections torqued
• Mechanical fixing completed

Stage 4: Power-On & Testing (Approx. 60 minutes)

Pre-Power Check

• Verify all covers are installed.
• Confirm no tools remain inside cabinet.
• Check insulation condition.
• Verify grounding connections.

Power-On Steps

1. Energize auxiliary control power.
2. Check control diagnostics.
3. Verify module identification.
4. Review fault messages.
5. Perform low-speed motor test.
6. Verify:
   • Current feedback
   • Phase operation
   • Drive alarms
   • Motor response

⚠️ Troubleshooting Note

If the drive reports phase module faults:

• Check module position.
• Verify fiber communication.
• Confirm hardware revision compatibility.
• Inspect gate control connections.

A common field mistake is replacing a power module without confirming the exact phase position and drive configuration.

Frequently Asked Questions (FAQ)

Q1: Is ABB S-073N 3BHB009884R0021 a PLC or controller module?

No. This is a power electronics phase module used in ABB medium-voltage drive systems. It is part of the drive power section, not a standard PLC control module.

Q2: Can I replace S-073N while the is energized?

No. This module is installed inside a medium-voltage drive power section. The system must be isolated, discharged, and verified safe before replacement.

Q3: Is S-073N compatible with all ABB drives?

No. Compatibility depends on the drive configuration, power rating, phase arrangement, and hardware revision. Verify the existing module identification before ordering.

Q4: What is the ABB part number for this module?

The ABB material/order number is 3BHB009884R0021, with ABB type designation S-073N.

Q5: Why is this module expensive compared with standard automation parts?

phase modules are specialized medium-voltage power conversion assemblies. Pricing reflects power semiconductor content, application-specific design, testing requirements, and limited spare-part availability.

Q6: Is this part new or refurbished?

Industrial spare parts may be available as New Original, New Surplus, or Refurbished Tested. Confirm condition, serial traceability, and test documentation before purchase.

Q7: What should I verify before ordering ABB S-073N?

Check:

• Existing drive model
