Selection Guide
Use the following criteria to confirm the VX4A1104 is the correct part for your application:
- Step 1 – Confirm Drive Model: Verify your drive is an ATV71 or ATV61 series. Check the nameplate on the drive enclosure.
- Step 2 – Check Frame Size: VX4A1104 is rated for specific frame sizes. Cross-reference with Schneider’s accessory catalog (document reference: ATV71 Installation Manual).
- Step 3 – Assess Wiring Requirements: Count the number of control signal terminals needed. If your application requires expanded I/O, consider the VX4A1204 or an I/O expansion card.
- Step 4 – Evaluate Replacement vs. Original: For warranty-sensitive or safety-critical installations, always use the original VX4A1104. For cost-sensitive retrofits, contact Konmask for verified alternatives.
- Step 5 – Confirm Stock & Lead Time: Contact [email protected] with your quantity and delivery requirements for availability confirmation.
