Description
Product Overview
The Metso Automation D100789 IPU-2 is a power unit module intended for use within compatible Metso/Valmet industrial automation equipment. In control-system maintenance, power-unit components are important to system availability because an incorrect replacement can prevent startup or affect connected equipment. Before ordering, confirm that the D100789 part number and IPU-2 designation match the module installed in the target system.
The Metso Automation D100789 is listed as discontinued by the manufacturer in available parts references. This makes revision identification and condition verification especially important for maintenance teams supporting legacy installations. Confirm the complete label, hardware revision, connector arrangement, and equipment configuration before approving a replacement. The module’s input voltage, output ratings, protection functions, and supported system configuration should be verified against the original documentation or physical nameplate rather than assumed from the part number alone.

Key Features and Maintenance Considerations
- Part-number identification: Use the full D100789 designation when checking replacement compatibility. Do not rely on a similar-looking model number alone.
- Legacy system support: Suitable evaluation for maintenance of existing Metso/Valmet equipment where the original IPU-2 module is installed.
- Revision verification: Check the complete model and revision markings. A listing for D100789 does not by itself confirm that every revision is interchangeable.
- Electrical compatibility: Verify the input supply, output requirements, grounding, and protective devices from approved technical documentation before energizing the replacement.
- Condition assessment: For new-old-stock or refurbished units, request condition details and any available inspection or functional-test records.
- Commissioning control: After installation, follow the equipment manufacturer’s startup procedure and confirm normal power status and system diagnostics before returning the equipment to service.
Recommended Applications
The may be relevant when maintaining a compatible Metso/Valmet automation installation that specifies the IPU-2 power unit. The exact controller or cabinet application should be confirmed from the original equipment documentation.
Replacement Checklist
- Match the installed part number to .
- Confirm the IPU-2 designation and revision marking.
- Compare connectors, mounting arrangement, and electrical ratings.
- Verify the replacement against the target system’s bill of materials or service manual.
- Record the module’s condition and test evidence before installation.
