Check the module label and confirm the complete part number 6SN1145-1AA01-0AA0. Compare it with the machine’s electrical drawings, equipment list, and existing hardware records.

Do not assume that similar model numbers indicate interchangeable components.

Step 2: Isolate the Electrical Supply

Shut down the equipment and isolate all relevant power sources according to the approved lockout/tagout procedure.

Drive equipment may retain hazardous electrical energy after disconnection. Follow the specified discharge times and verify the absence of hazardous voltage before handling electrical connections.

Step 3: Inspect the Module

Examine the housing, terminals, connectors, and mounting surfaces for physical damage, contamination, corrosion, or signs of overheating. Do not install a module with damaged electrical connections or a compromised enclosure.

Step 4: Confirm the Installation Space

The supplied dimensions are 102 × 483 × 305 mm. Verify that the designated enclosure provides adequate space for the module, associated wiring, mounting hardware, and required cooling clearances.

Confirm the approved mounting orientation and mechanical support requirements before proceeding.

Step 5: Verify Electrical Requirements

Review the applicable wiring diagrams and technical documentation to identify the correct supply connections, grounding arrangement, protective devices, and interfaces to associated drive equipment.

Never infer voltage ratings, current limits, or terminal assignments from the model number alone.
