powered?\u003c\/p\u003e\n\u003cp\u003eA: No. The 1745-E104 interconnect bus must be connected or disconnected only when primary line power is isolated to prevent backplane communication errors or hardware faults.\u003c\/p\u003e\n\u003cp\u003eQ: What power input specs does the 1745-E104 require for internal logic operation?\u003c\/p\u003e\n\u003cp\u003eA: The module operates on an AC line voltage rating of 10-250 VAC at 50\/60 Hz with a nominal current draw of 0.22 A.\u003c\/p\u003e\n\u003cp\u003eQ: Is a separate network interface required to communicate with the SLC 100 base processor?\u003c\/p\u003e\n\u003cp\u003eA: No. Communication is handled natively via the bus interconnect cable connected directly to the SLC 100 CPU rack.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eTurn off primary power supplying the main SLC 100 unit and expansion chassis prior to hardware installation or cable attachment.\u003c\/li\u003e\n\u003cli\u003eFasten the chassis firmly to a grounded mounting panel to maintain proper frame ground continuity and mechanical stability.\u003c\/li\u003e\n\u003cli\u003eKeep interconnect expansion cables isolated from high-voltage AC lines and VFD motor cables to minimize electromagnetic interference.\u003c\/li\u003e\n\u003cli\u003eProvide a minimum top and bottom clearance of 2.0 in (50.8 mm) within the enclosure to allow sufficient heat dissipation.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Allen-Bradley","offers":[{"title":"Default
