carrier?\u003c\/p\u003e\n\u003cp\u003eA: The total length of the LocalBus, including all internal power buses, interface carrier buses, and connecting cables, cannot exceed 6.5 m (21.3 ft.) regardless of whether the system is horizontally or vertically mounted.\u003c\/p\u003e\n\u003cp\u003eQ: How does the LocalBus distribute power and communications across the subsystem?\u003c\/p\u003e\n\u003cp\u003eA: The LocalBus consists of an internal power bus on the Power Controller Carrier, busses on associated I\/O interface carriers, and connecting cables that supply 12 VDC system power and provide communication connections between cards.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMount the power supply and associated carrier securely within the designated DeltaV cabinet slot, ensuring proper alignment and adequate clearance for thermal dissipation.\u003c\/li\u003e\n\u003cli\u003eVerify that LocalBus cabling length constraints (maximum 6.5 m \/ 21.3 ft. total) are strictly observed across all interconnected carriers before system energization.\u003c\/li\u003e\n\u003cli\u003eRoute power distribution and CAT 5 screened (ScTP) twisted-pair network cables separately from high-voltage power lines and variable frequency drives to prevent electromagnetic interference.\u003c\/li\u003e\n\u003cli\u003eEnsure that the carrier chassis and system grounding points are securely bonded to the cabinet earth bar to maintain proper surge protection and signal integrity.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Emerson","offers":[{"title":"Default
