Over-tightening the mounting thread into steel casings without high-quality anti-seize compound can result in galling, making future maintenance or adjustment of the probe penetration depth impossible without damaging the threads.\u003c\/p\u003e\n\n\u003ch3\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h3\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eAlways use the provided grommet that closely matches your probe cable outer diameter inside the seal grip. A loose cable seal allows moisture accumulation inside the junction head, which degrades the RF signal characteristics of the proximal matching system. For long-term reliability in wet environments, construct a drip loop in the conduit immediately prior to entry into the housing fittings.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cdiv style=\"background-color: #fff5f5; border-left: 4px solid #c53030; padding: 1rem; margin-bottom: 1.5rem; color: #9b2c2c;\"\u003e\n  \u003cstrong\u003eCRITICAL WARNING:\u003c\/strong\u003e Prior to mounting or adjusting the probe housing, ensure the machine is completely de-energized and locked out.
