How to Install the DXA Controller

This guide provides step-by-step instructions for installing and configuring the DXA Controller in industrial applications, ensuring safe and effective operation.

Estimated time: 45m

Tools needed:

Screwdriver, Wire strippers, Multimeter

Supplies needed:

Mounting screws, Terminal connectors, Color-coded gaskets

  1. Mount the controller

    Secure the controller to the DIN rail using the integrated clips. Ensure the controller is level and firmly attached.

  2. Prepare the wiring

    Remove an adequate length of cable outer sheath and strip the conductor insulation to the length indicated in Table T2. Ensure that the cable sheathing extends through the cord grip into the handle or box.

  3. Connect the ground

    Connect all metal parts to ground using the provided ground terminals. Ensure that one ground terminal is factory-wired to the ground contact and should not be removed.

  4. Wire the terminals

    Insert the conductor fully into the terminal and tighten the terminal screws to the torque indicated in Table T2. Do not back terminal screws completely out.

  5. Install color-coded gaskets

    Insert the color-coded gaskets between the device and its rear accessory to maintain the IP rating. Position the protrusions on the gasket on the latch sides.

  6. Verify connections

    Use a multimeter to verify that all connections are secure and that there are no short circuits. Check the continuity of the ground circuit.

  7. Calibrate the controller

    Follow the manufacturer's instructions for programming and configuration settings to ensure the controller operates correctly in its intended application.

  8. Conduct a final inspection

    Inspect all connections, ensure that the safety shutter is functioning properly, and verify that the installation complies with local electrical codes.
