Siemens designates 1790L816A as a Inverter Connection Kit associated with the MICROMASTER control platform.
Within the control architecture, this product serves the equipment role stated in its description and should be selected by exact model identity rather than by appearance or a broadly similar name. Existing connection and module records should guide replacement work.
MICROMASTER provides the platform context for this product, while the AC drives classification identifies its broader automation role. Exact application should follow the installed system configuration. This helps preserve the function assigned to the installed control node.
For maintenance or replacement work, the exact module designation should be checked against the installed hardware, wiring records, and control-system documentation before the component is placed into service. The product remains part of the broader control and signal-handling arrangement.
