How to Install the SPeX Single-Pole Power Connector

This guide provides step-by-step instructions for installing and configuring the SPeX single-pole power connector for use in explosive atmospheres.

Estimated time: 1h

Tools needed:

Screwdriver, Wire strippers, Crimping tool, Multimeter, Wrench set

Supplies needed:

Mounting screws, Terminal connectors, Cable gland, Color-coded rings, Isolating ring

  1. Disconnect Power

    Ensure that all sources of power to the circuit are disconnected to eliminate the risk of electrical shock before starting the installation.

  2. Insert Cable

    Insert the cable through the cable gland and the handle or inclined sleeve, ensuring it is properly positioned for secure connection.

  3. Wire the Pilot Circuit

    Use flexible conductors with a cross-sectional area between 0.5 and 1 mm² (16 to 20 AWG) to connect the pilot wires to the microswitch using the supplied isolated crimping lugs.

  4. Wire the Main Conductors

    Strip the main conductors by 1.8 inches (46 mm) and crimp the threaded lug or ferrule with the appropriate tool. Tighten the connection with a wrench to a torque of approximately 70 N·m (95 ft-lbs).

  5. Assemble the Connector

    Assemble the handles on the body of the connector using the supplied gaskets and screws. Tighten the cable gland securely to achieve IP65/IP66 rating.

  6. Install the Isolating Ring

    When mounting the SPeX on a metallic support, position the isolating ring correctly and ensure the black flat gasket is used to guarantee watertightness.

  7. Verify Connections

    Use a multimeter to check the electrical continuity of the ground circuit and ensure all connections are secure and properly insulated.

  8. Final Assembly and Testing

    Reassemble any protective caps and ensure the installation is complete. Test the system to confirm proper operation before energizing.
