How to Install the HPS Imperator® Control Transformer

This guide provides step-by-step instructions for installing and wiring the HPS Imperator® Control Transformer, including the setup of optional accessories.

Estimated time: 45m

Tools needed:

Screwdriver, Wire strippers, Multimeter

Supplies needed:

Mounting screws, Fuse clips, Voltage links, Finger guard

  1. Mount the transformer

    Secure the HPS Imperator® transformer to the mounting surface using appropriately sized mounting screws. Ensure the transformer is level and stable.

  2. Install fuse clips

    Remove the captive washer screws from the terminal block and install the fuse clips using the new terminal screws provided in the accessory kit. Ensure all screws are torqued to 12 to 14 inch-lbs.

  3. Connect voltage links

    Install the voltage links between the primary or secondary terminal bays as indicated in the instruction sheet included with your transformer. Ensure connections are secure and properly insulated.

  4. Attach finger guard

    If using a finger guard, attach it to the transformer following the provided assembly drawing. Ensure it is securely fastened to prevent accidental contact with live components.

  5. Verify connections

    Use a multimeter to check all connections for continuity and proper voltage levels. Ensure that all wiring complies with the recommended wire size of 18 AWG to 14 AWG for solid wire.
