3.2 Installation
Installation on a DIN rail
1. Insert the device with the respective guide
– Top guide for S7-1500 standard rail
– Center guide for S7-300 standard rail
– Bottom guide for DIN rail
2. Tilt the device to the back until the mounting rail release audibly locks in place
3. Ground the mounting rail.
NOTICE
Grounding
For reasons of electrical safety, the DIN rail must be connected to the protective conductor
system (PE) of the electrical system.
Note
Protecting the modules from slipping on the DIN rail
If you install the modules in an area with mechanical load, use suitable clamping devices at
both ends of the device group to secure the modules on the DIN rail, e.g. Siemens and
retainer 8WA1808.
The end retainers prevent the modules separating under mechanical load.
