Installation Guidelines

Follow these steps to install your Schneider Electric 140CRA21110 module correctly.

1. Power Down the Rack – Turn off all power to the Quantum backplane.

2. Select the Slot – Choose an available slot in the backplane.

3. Insert the Module – Slide the 140CRA21110 into the selected slot.

4. Secure the Module – Tighten the top and bottom retaining screws.

5. Connect Power – Wire 115/230V AC to the 7-pole terminal block.

6. Install the Fuse – Insert a 1.5 A fuse in the power circuit.

7. Connect I/O Cables – Attach remote I/O dropson cables to the single port.

8. Apply Power – Turn on the supply and verify module status.

Do not exceed 50 VA total power consumption. Oversized loads will activate the short-circuit protection.
