RACK MOUNTING

Panel-mounted variants can also be rack mounted using single-tier rack frames (our part number FX0021 101), as
shown in the figure below. These frames are designed with dimensions in accordance with IEC 60297 and are
supplied pre-assembled ready to use. On a standard 483 mm (19 inch) rack this enables combinations of case
widths up to a total equivalent of size 80TE to be mounted side by side.
The two horizontal rails of the rack frame have holes drilled at approximately 26 mm intervals. Attach the products
by their mounting flanges using M4 Taptite self-tapping screws with captive 3 mm thick washers (also known as a
SEMS unit).
Caution:
Risk of damage to the front cover molding. Do not use conventional self-tapping
screws, including those supplied for mounting MiDOS products because they have
slightly larger heads.
Once the tier is complete, the frames are fastened into the racks using mounting angles at each end of the tier.

Figure 164: Rack mounting of products

Products can be mechanically grouped into single tier (4U) or multi-tier arrangements using the rack frame. This
enables schemes using products from different product ranges to be pre-wired together before mounting.
Use blanking plates to fill any empty spaces. The spaces may be used for installing future products or because the
total size is less than 80TE on any tier. Blanking plates can also be used to mount ancillary components. The part
