Modular order for the development of mechanical structures for electronic equipment practices - Part 2-3: Sectional specification - Interface co-ordination dimensions for the 25 mm equipment practice.
Extended detail specification - Dimensions for subracks, chassis, backplanes, front panels and plug-in units.
IEC 60917-2-3:2006 provides additional dimensions for a modular range of subracks and associated plug-in units based on IEC 60917-2-2.
A typical subrack consists of a frame design with mounting dimensions for installation into racks or cabinets in accordance with IEC 60917-2-1. The aperture dimensions of a subrack are 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 and dimensions of rear-mounted plug-in units.
