• Issue: Output voltage drops below expected levels.
• Solution:
  • Verify that the load does not exceed the module’s maximum output current (20 A).
  • Check for any short circuits or faults in connected devices.
  • Inspect the module for damage or internal faults.

4. Noise Issues

• Issue: The module produces excessive noise during operation.
• Solution:
  • Ensure that the module is installed on a stable surface to minimize vibrations.
  • Check for loose components or connections that may contribute to noise.
  • If noise persists, consider consulting technical support for further assessment.

5. Faulty Diagnostics

• Issue: Diagnostic indicators do not function or show errors.
• Solution:
  • Refer to the user manual for error codes and troubleshooting steps.
  • Perform a reset of the module and check for firmware updates if applicable.
  • Contact ABB technical support if the issue continues.
