Installing a new component
1. Position the new component with the mounting rail guide at the upper edge of the
standard mounting rail and press down on the component to lock it into place.
If it is difficult to snap it into place, simultaneously press the slider as described for rail
mounting.
2. Remove the plastic cover of the connecting socket (if there is an additional module at the
right-hand side).
3. Connect the new component to the adjacent components using the connecting plug.
4. Connect all of the plug-in terminals at the new component and carefully check that the
wiring is correct. If the basic unit was replaced, then also connect the
Ethernet/PROFINET connection.
5. Check all of the settings (potentiometer, DIP switches) at the new components that have
been installed to ensure that the correct values are set.

NOTICE
Incorrect response and damage after switching on again
When replacing an individual component it must be ensured that the new component
used is the identical type to the one that you have removed and has the same settings.
This is to avoid any possible incorrect response and damage after you switch on again.
After replacing the component ensure that the wiring of the plug-in terminals is correct.
