适用范围:This part of IEC 60917 provides additional dimensions for a modular range of subracks andassociated plug-in units based on IEC 60917-2-2.A typical subrack consists of a frame design with mounting dimensions for installation intoracks or cabinets in accordance with IEC 60917-2-1. The aperture dimensions of a subrackare specified in order to meet the mounting dimensions of front plug-in units.This part of IEC 60917 comprises– additional dimensions for subracks and subrack associated plug-in units with injector/extractor handle;– dimensions for basic electromagnetic shielding provisions;– dimensions of the key/coding system for subrack and plug-in units;– dimensions of the alignment pin for front panel and plug-in unit;– dimensions of electrostatic discharge provisions;– dimensions of rear-mounted plug-in units.Connector-related dimensions are given in Annex A.In order to ensure the compatibility of plug-in units into the subrack, inspection dimensionsand connector-dependent dimensions are defined.NOTE The drawings used in this part of IEC 60917 are not intended to indicate product design, only the specificdimensions that are used.
