4.1.2 T- or G-section DIN-rail mounting – with DMK01 mounting kit
See Figures 4.1 and 4.2.
Cut two pieces of T- or G-section DIN-rail to the required length and fi x them side-by-side with
centres spaced appropriately – 132mm (CPS04), 113mm (CPS08/16) or 100mm (CPS24).
With reference to Figure 4.4, clip the appropriate number of mounting feet (7) to the DIN rail
(8) at centres ‘A’ (4 for each 4/8-way, 6 for each 16-way and 8 for each 24-way backplane)
(Figure 4.3).
Select the appropriate number of No. 6 x 1/2-inch screws.
Place a locking washer (2) and a plain washer (3) onto each No. 6 x 1/2-inch screw (1)
(Figure 4.3).
Insert the assemblies through the mounting holes A on the backplane (Figures 4.1 and 4.3).
Fit spacers (5), retaining them with the washers (6) (Figure 4.3).
Locate the assemblies over the mounting feet and attach the screws (1) to the feet (Figure
4.3).
NOTE
: For vertically orientated backplanes it is recommended that end stops with screw fi xings are
fi tted on the DIN rails immediately below the lowest backplane fi xing. This will avoid the chance of
backplane slippage down the DIN rail.
4.1.3 19-inch rack mounting – CPS24 backplanes with HMP24 mounting plate
See Figure 4.4.
Place an unloaded backplane onto the HMP24 mounting plate.
Attach the backplane to the mounting plate at centres A with the eight M4 x 12mm screws
provided.
Attach the assembly to the 19-inch rack centres at D.
4.2 Backplanes – identifi cation and tagging
Backplane labelling facilities include marked areas for identifying backplanes, specific module locations
and system connections (multiway backplanes only). Mounting holes for earth-rail and tagging-strip
attachments are similarly marked
4.21 Backplane
identifi cation labels
Attach a suitably marked label to the area marked BACKPLANE IDENT. to identify an
individual backplane (Figure 4.5).
Attach suitably marked MPL01 module position labels to the areas marked MODULE IDENT
(Figure 4.5).
