Ground loops can be avoided by ensuring the module's metal mounting tabs are bonded directly to a clean, low-impedance machine ground plane rather than relying solely on the cable shielding.\n\u003c\/p\u003e\n\n\u003ch3 style=\"color: #1a365d; border-bottom: 2px solid #2b6cb0; padding-bottom: 0.25rem;\"\u003eInstallation Guidelines\u003c\/h3\u003e\n\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 De-energize all system power sources (both US control\/sensor power and UP actuator power) before initiating installation, cable routing, or module replacement.
