Installation location
Introduction
Install the CPU 1515SP PC2 in a suitable housing/control cabinet with sufficient mechanical
strength, fire protection and at least IP54 degree of protection according to EN 60529, and
take into consideration the ambient conditions for operating the devices.
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
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 int
ervals of approx.
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 123).
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.
