How to Install the Open Core & Coil Industrial Control Transformer

This guide provides step-by-step instructions for installing and wiring the Open Core & Coil Industrial Control Transformer, including optional accessories.

Estimated time: 45m

Tools needed:

Screwdriver, Wire strippers, Multimeter

Supplies needed:

Mounting screws, Terminal connectors, Voltage Link Kit, Jumper Kits, Finger Guard Kit (optional), Fuse Block Adapter Kit (optional)

  1. Mount the transformer

    Secure the transformer to the mounting surface using appropriately sized mounting screws. Ensure that the hardware is suitable for the weight of the transformer.

  2. Connect the voltage links and jumpers

    Install the Voltage Link Kit and Jumper Kits as per the provided assembly drawings. Ensure all connections are secure and torque terminal screws to 12-14 inch-lbs.

  3. Install optional accessories

    If using the Finger Guard Kit or Fuse Block Adapter Kit, follow the specific installation instructions for these accessories. Ensure that the finger guard is mounted only on units with a molded terminal block.

  4. Wire connections

    Use the recommended wire sizes (18 AWG to 14 AWG for solid wire and 18 AWG to 12 AWG for stranded wire) for all bare wire connections. Use ring or spade connectors if using wire sizes outside the specified range.

  5. Verify connections

    Double-check all wiring connections for security and correctness. Use a multimeter to verify proper voltage levels before powering on the transformer.
