INTENDED USER
Personnel installing, operating, or maintaining the mounting units should read this manual before performing any installation, maintenance or replacement procedures. Installation requires an engineer or technician with experience in handling electronic circuitry. FEATURES The backplane in these mounting units has several features: • I/O expander bus interconnect cables based on 2.54-millimeter (0.1-inch) center ribbon cable technology for enhanced robustness. Cables come in choice of two lengths: 38 millimeter (1.5 inches) and 171 millimeter (6.75 inches). • Ability to segment Controlway or module bus into three segments on the backplane, which provides for increased density and lower costs. • Available with or without primary power distribution. Module mounting unit with primary power distribution is only needed for AC and DC Modular Power Systems configured for primary power distribution.
