Eight RJ45 connectors provide tap-off connections, while two RJ45 connectors support daisy-chain routing. The underside 4-point screw terminal block provides the interface for the Modbus trunk cable.\u003c\/p\u003e\n\u003cp\u003eThe unit is a communication distribution component rather than an active Modbus protocol processor. Installation should maintain the intended trunk and branch topology and avoid unnecessary parallel cable routing that can affect serial communication integrity.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How is the Modbus trunk cable connected to the LU9GC3?\u003cbr\u003eA: The Modbus trunk cable is connected through the 4-point screw terminal block located on the underside of the splitter box.\u003c\/p\u003e\n\u003cp\u003eQ: How many RJ45 ports are provided?\u003cbr\u003eA: The LU9GC3 has 10 RJ45 connectors: 8 for tap-off connections and 2 for daisy-chain connections.\u003c\/p\u003e\n\u003cp\u003eQ: How is the LU9GC3 mounted?\u003cbr\u003eA: It can be clipped onto a 35 mm DIN rail or fixed to a panel using 2 screws.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the LU9GC3 on a mechanically secure 35 mm DIN rail or panel surface. Route the Modbus trunk cable separately from high-current power and switching conductors where practical. Maintain correct conductor identification and termination at the 4-point screw terminal block.\u003c\/p\u003e\n\u003cp\u003eFor shielded Modbus cable, apply the system-specified shield bonding method and avoid creating unintended ground loops. RJ45 communication cables should be routed with adequate separation from motor, contactor, and soft starter power wiring. Verify the intended tap-off and daisy-chain arrangement before energizing the communication network.\u003c\/p\u003e","brand":"Schneider","offers":[{"title":"Default Title","offer_id":50124575211762,"sku":"LU9GC3","price":15.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0730\/5589\/5794\/files\/LU9GC32.jpg?v=1789890103","url":"https:\/\/www.petrospare.com\/products\/schneider-electric-lu9gc3-tesys-u-modbus-communication-splitter-box","provider":"Petro Spare Industrial Limited","version":"1.0","type":"link"}
