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
- Mount the controller
Secure the DXA Controller to the DIN rail using the integrated clips. Ensure the controller is level and firmly attached.
- Prepare the wiring
Remove an adequate length of cable outer sheath and strip the conductor insulation according to the specifications in Table T2. Ensure the cable sheathing extends through the cord grip for proper sealing.
- Connect the ground
Connect all metal parts to the ground terminals provided on the DXA Controller. Ensure that the ground connection is secure and that the factory-wired ground terminal remains connected.
- Wire the terminals
Insert the prepared conductors into the contact terminals without fully removing the terminal screws. Tighten the screws to the specified torque in Table T2 to secure the connections.
- 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 gasket are positioned correctly.
- 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.
- Test the device
Power on the DXA Controller and test its functionality by connecting it to a compatible device. Ensure that the safety shutter operates correctly and that the device is functioning as intended.
