What to consider when installing in a PC cabinet for industrial computers
Speaking of installation: at most locations, a 19-inch PC case is available as a PC cabinet for industrial computers. It is called 19-inch rack in English and is standardized throughout Europe in accordance with EIA 310-D, IEC 60297 and DIN 41494 SC48D. The name is derived from the front panel width specified in it, which is 19 inches or 48.26 centimeters in German units. Most of the time, the individual devices are fastened with four screws in the rows of holes in vertically running sheet metal angles near the front edges of the shelves, each with a width of 5/8 inches (15.88 mm). When installed in the standard PC cabinet, a 450.85 mm wide opening is available for every industrial PC. Also note the height units of the devices (HE for short, also known as rack units in English). One height unit corresponds to 1.75 inches or 4.445 centimeters, and depending on the height, 1U, 2U, 3U and 4U devices are differentiated.
