Mount the ET 200SP distributed I/O system on a mounting rail in accordance with EN 60715
(35 × 7.5 mm or 35 × 15 mm).
You need to 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.
200SP distributed I/O system is exposed to vibration and shock loads, both ends of
200SP system assembly must be mechanically fixed to the mounting rail (e.g using
-1PH01 ground terminals). This measure prevents the ET 200SP distributed I/O
system from shifting to the side.
200SP distributed IO system is exposed to increased vibrations and shock, we
recommend that you screw the mounting rail to the mounting surface at intervals of approx.
200 mm.
The following are suitable surfaces for the mounting rails:
● Steel strip in accordance with Appendix A of EN 60715 or
● Tinned steel strip. We recommend these in conjunction with the mounting rails in the
section Accessories/spare parts (Page 286).
Note
If you use mounting rails from other manufact
urers, make sure that they have the
required properties for your ambient climatic conditions.
