The controller is housed in a 4.5-inch (114 mm) deep, black plastic case with a dark gray elastomer bezel, that can be panel
mounted in a 1/4 DIN cutout. The plug-in chassis allows easy access to the controller board and its various option boards. All
power, input, and output wiring are connected to screw terminals on the rear panel. (See Figure 6.)
