Ensure that the mounting bracket does not encroach on the active field zone of the probe tip.\u003c\/p\u003e\n\n\u003ch4\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eThe FluidLoc cable must never be spliced, cut, or altered. The precise electrical length of the 9.0-meter cable is part of the tuned radio frequency (RF) circuit; changing the length permanently alters the calibration curves. Always verify the DC gap voltage at the Proximitor output during mechanical installation to confirm you are within the linear operating range before locking the mounting assembly.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cdiv style=\"background-color: #fff5f5; border-left: 4px solid #c53030; padding: 15px; margin-bottom: 1.5rem;\"\u003e\n  \u003cstrong style=\"color: #9b2c2c;\"\u003eCRITICAL WARNING:\u003c\/strong\u003e \u003cspan style=\"color: #9b2c2c;\"\u003eVerify that the machinery is completely shut down, locked out, and tagged out prior to installation.
