Application planning
5.4 Installation location
Mounting rail
You must ground the mounting rail separately in the control cabinet. Exception: If you install the
rail on grounded, zinc-plated mounting plates, there is no need to ground the rail separately.
Note
If the ET 200SP distributed I/O system is exposed to vibration and shock loads, both ends of the
ET 200SP system assembly must be mechanically fixed to the mounting rail (e.g using
8WA1010-1PH01 ground terminals). This measure prevents the ET 200SP from shifting to the
side.
Note
If the ET 200SP distributed I/O system is exposed to high vibration and shock load, we
recommend that you screw the mounting rail to the mounting surface at intervals of approx.
200 mm.
Suitable surface finishes are:
• Steel strip in accordance with Appendix A of EN 60715 or
• Tinned steel strip. We recommend the use of the mounting rails in section (Page 113).
Note
Mounting rails of other manufacturers
If you use mounting rails from other manufacturers, ensure that they have the properties
required for your climatic and mechanical ambient conditions.
