Guidelines for the Planning and Installation of the Product S5-95F
3.3.2 Example of Rack Mounting for EMC
Picked-up interference should pass to large metal surfaces. You should therefore secure standard
mounting rails, shield and protective conductor bars to metal structural elements.
For wall mounting
in particular, installation on reference potential surfaces made of sheet steel has proved
advantageous.
When installing shielded cables, provide a shield bar for connecting the cable shields. The shield bar
can also be the protective conductor bar.
Ensure the following for rack and wall mounting:
. Use only standard mounting rails to EN 50022 to mount the modules of your
S5-95F. Only these
mounting rails guarantee a tight fit of the modules and a satisfactory discharge of picked-up
interference.
. Suitable contacting aids should be used on painted and anodized metal parts. Use special
contact washers
or remove the insulating protective layers.
.
Provide large-area,
low-impedance
metal-to-metal connections when
securing the
shield/protective conductor bar:
