Grounding

Proper grounding of the Hunter Node 100 is essential for safety and reliable operation. The node’s enclosure should be connected to a dedicated grounding electrode that meets local electrical code requirements. Use a copper grounding wire of at least 4 AWG‚ routed directly from the node’s grounding terminal to the electrode. Avoid long runs or unnecessary bends‚ as these can increase resistance and compromise the fault‑current path.

When installing the grounding conductor‚ ensure it is securely fastened to the node’s metal chassis with a corrosion‑resistant clamp. The clamp must make full contact with the chassis and the wire‚ providing a low‑impedance connection. The grounding wire should be buried at least 18 inches below the surface or placed in a conduit if exposed to moisture or mechanical damage.

After installation‚ test the ground resistance with a clamp‑meter or a ground resistance tester. A reading below 25 ohms is generally acceptable‚ but local regulations may require lower values. If the resistance is too high‚ add additional grounding rods or increase the wire gauge to reduce impedance.

It is also important to isolate the node’s power supply from the control circuitry. The power supply’s grounding point should be bonded to the same electrode as the node‚ preventing potential differences that could cause arcing or equipment damage. Keep all grounding connections free of paint‚ oil‚ or other contaminants that could impede conductivity.
