Both parts are reworked in order to meet the latest market requirements of the electronics i

Some parts of this standard contain dimensions of IEC 60917-2-1 and ETSI EN 300119. The merge of the two parts into one updates the scope and improves the overview of the mod

There are two mounting hole types as shown in detail “A”. The front panel thickness is not def

The higher number of mounting holes may be used in case of high load applied to the front panel or other stability requirements. For 6

37、U front panels two types of hole spacing are possible (see Table1 and Table 2). The front panel dimensions apply also to chassis and subracks.

They are typically an

45、chored to the floor at the lower part and to the ceiling and/or wall at the top. Each pair of vertical members will allow the attachment of front panels, chassis and subracks, in accordance with this series of standards. The coordination dimension of the fixed rack structures is equal to the theoret

46、ical centre distances within a suite of racks. Each vertical rack member may be separated from or combined with the vertical member of the adjacent rack, providing the width coordination dimension is maintained. The heights and depth of such structures are not covered by this standard. Table 3 Width

Figure 6 illustrates the mounting grid in two different types: Type I: The holes correspond with the front panel, subrack and chassis mounting hole positions. Type II: The same grid includes additional mounting holes (universal hole s

They may be used for the mounting of other structural parts, such as telescopic slide brackets or angles. Type II shall be used as the preferred mounting grid. The mounting positions provide for attachment hardware such as thread clips, nuts, integrat
