Installation should be performed by qualified personnel familiar with industrial drive equipment and applicable electrical safety procedures. The manufacturer’s instructions for the exact module and complete drive system take precedence over this general checklist.

Step 1: Verify the Model Number

Check the module label and confirm the complete part number 6SN1145-1AA01-0AA1. 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 systems 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, connectors, terminals, and mounting surfaces for physical damage, contamination, corrosion, or signs of overheating. Do not install a module with damaged connections or a compromised enclosure.

Step 4: Confirm Installation Space

The supplied dimensions are 305 × 102 × 483 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.

Do not infer voltage ratings, current limits, or terminal assignments from the model number alone.

Step 6: Install the Module

Mount the module according to the manufacturer’s instructions. Ensure that it is securely supported and that all required mechanical and electrical connections are correctly engaged.

The supplied weight is 9 kg. Use appropriate handling methods and assistance where necessary to prevent injury and avoid damage during installation.

Step 7: Inspect the Complete Drive Configuration

Before restoring power, verify that the module occupies the intended position in the system and that all connected components match the approved configuration. Inspect wiring, grounding, protective devices, and cable routing.
