Route all cabling from the load cells separate from three-phase motor lines and variable frequency drives (VFDs) to prevent signal drift. For systems utilizing multiple load cells in a single application, an external junction summing box must be installed before running a single structured cable to the module inputs.\u003c\/p\u003e\n\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003e\u003cstrong\u003eCommissioning \u0026amp; Wiring Tips:\u003c\/strong\u003e Utilize high-quality shielded twisted-pair (STP) cabling for the load cell connection. For cable run distances exceeding 5 meters, it is recommended to configure a 6-wire load cell connection using the EXC and SENSE feedback loops; this dynamically offsets voltage losses over long distances, preserving the module's 24-bit measurement integrity.\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: 20px; color: #9b2c2c;\"\u003e\n  \u003cstrong\u003eCRITICAL WARNING:\u003c\/strong\u003e De-energize all power sources supplying the host NX-bus terminal and the auxiliary field devices prior to inserting or withdrawing the physical NX-RS1201 module.
