Removing and inserting I/O modules

Requirement
Remove or insert front connectors and I/O modules only when the voltage is switched off.
NOTICE
Physical damage can occur
If you install or uninstall front connectors and/or I/O modules with switched-on voltage, this
can lead to undefined conditions in your plant.
The S7-1500 automation system/ET 200MP distributed I/O system may be damaged as a
result.
Therefore only install/uninstall front connectors and/or I/O modules with switched-off
voltage.
Therefore during the planning of a plant always make sure to comply with the necessary,
pertinent standards and safety guidelines.
