How to Install the ST3GR-G Controller

This guide provides step-by-step instructions for installing and wiring the ST3GR-G Controller, ensuring proper setup and configuration.

Estimated time: 45m

Tools needed:

Screwdriver, Wire strippers, Multimeter

Supplies needed:

Mounting screws, Terminal connectors

  1. Prepare the conduit

    Properly cut the flexible conduit with a clean, square end cut using a sharp hacksaw or power band saw. Ensure the cut is smooth to avoid damage during installation.

  2. Assemble the grounding components

    Remove the round shape support from the PVC coating on the gland nut. Slide the gland and nylon sealing ring onto the conduit, ensuring the open side of the lug on the ground ring is facing the gland nut.

  3. Install the grounding cone

    Thread the ground cone into the conduit and slide the body onto the cone. Then, slide the gland nut and sealing ring down to the body and tighten the gland according to the torque chart provided.

  4. Connect the grounding conductor

    Install the grounding conductor in the lug and tighten the lug screw according to the torque table. Ensure all connections are secure to prevent any electrical issues.

  5. Verify the installation

    Use a multimeter to check all connections for continuity and proper grounding. Ensure that all circuits are de-energized before performing this verification.
