ICS Code (Mechanical structures for electronic equipment): 31.240
scope:

This part of IEC 60917 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;

 - 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 dimensions and connector-dependent dimensions are defined.

NOTE  The drawings used in this part of IEC 60917 are not intended to indicate product design, only the specific dimensions that are used.
