Introduction

IEC 60917 (all parts) specifies mechanical knots for metric cabinets, racks, subracks, enclosures and inserts based on metric modular sequence sizes

Structure and size. Subsequent development of IEC 60917 (all parts) compared to IEC 60297 provides a more harmonized size

Rational design practice.

IEC 60297 (all parts) also specifies the structure and interface dimensions for 19in racks, racks and compatible bays and enclosures. by

A long history of IEC 60297 (all parts) and its applications, combined with 19in-based cabinets, racks, bays and chassis

It will be widely used in all industrial electronics fields in the world.

In order to meet the requirements of the IEC 60917 series (metric standards) combined with the IEC 60297 series (19in standard), resulting in 19in

Installing a metric box or chassis in a standard cabinet or rack, and vice versa, installing a 19-inch box or gantry in a metric cabinet or rack

Chassis.

To address this requirement and need, install a metric or 19in box or chassis to a cabinet or machine that meets 19in or metric standards.

Frame to determine the appropriate flange fit size. These sizing sizes specify that the electronic equipment is installed in an existing cabinet or rack.

1 Scope

This section of GB/T 19290 specifies the mounting flange dimensions for metric bays or enclosures that can be mounted in a 19-in cabinet or rack.

Additional dimensions for the subrack or enclosure comply with IEC 60917 (all parts), additional dimensions for 19 in cabinets or racks in accordance with IEC 60297

(all parts).

EMC, seismic, climatic, and environmental requirements and tests are specified in IEC 61587 (all parts).

The diagrams used in this section are not intended to guide product design, only the dimensions specified in those standards should be used.

The terminology used is in accordance with IEC 60917-1.
