3 MOUNTING THE DEVICE
The products are available in the following forms
● For flush panel and rack mounting
● Softw
are only (for upgrades)
3.1 FLUSH PANEL MOUNTING
Panel-mounted devices are flush mounted into panels using M4 SEMS Taptite self-tapping screws with captive
3 mm thick w
ashers (also known as a SEMS unit).
Caution:
Do not use conv
entional self-tapping screws, because they have larger heads and could
damage the faceplate.
Alternatively, you can use tapped holes if the panel has a minimum thickness of 2.5 mm.
For applications wher
e the product needs to be semi-projection or projection mounted, a range of collars are
available.
If several products are mounted in a single cut-out in the panel, mechanically group them horizontally or vertically
into rigid assemblies before mounting in the panel.
Caution:
Do not fast
en products with pop rivets because this makes them difficult to remove if
repair becomes necessary.
3.1.1 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 t
o 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.
