How to Install the DXA Controller

This guide provides step-by-step instructions for the installation and initial setup of the DXA Controller in industrial applications.

Estimated time: 45m

Tools needed:

Screwdriver, Wire strippers, Multimeter

Supplies needed:

Mounting screws, Terminal connectors, Color-coded gaskets

  1. Mount the controller

    Install the receptacle at a downward angle, ensuring the latching pawls are positioned at the top and bottom. Secure the controller to the mounting surface using the provided screws.

  2. Prepare the wiring

    Remove the outer sheath of the cable to the appropriate length and strip the conductor insulation as specified in Table T2. Ensure the cable sheathing extends through the cord grip for proper sealing.

  3. Connect the ground

    Connect all metal parts to the ground terminals provided on the controller. Ensure that the factory-wired ground terminal remains connected to maintain grounding for the other terminals.

  4. Wire the terminals

    Insert the stripped conductors into the terminal blocks without completely removing the terminal screws. Tighten the screws to the specified torque in Table T2 to secure the connections.

  5. Install color-coded gaskets

    Insert the color-coded gaskets between the device and its rear accessory to maintain the IP rating. Ensure the protrusions on the gaskets are positioned correctly.

  6. Verify connections

    Use a multimeter to check the continuity of the ground circuit and verify that all connections are secure and properly tightened.
