44、d connector has14press-in terminations, which assure the mechanical fixation on the printed board. The fixed board connector is bolted on, through a hole in the backplane. The coding configuration is set by mounting the correct coding devices in their correct positions on the connectors. Generally,
45、two pairs of connectors are used, one at the top edge and one at the bottom edge of the plug-in unit. They fit between the plug-in unit guides of the subrack and the ends of the multipole connector(see2.3.2). 1.2 Ratings and characteristics Figure 1 Recommended method of mounting Current rating: 15
