8.2 Set the I/O module to the maintenance position
CAUTION
Using the maintenance position
If I/O modules are in the maintenance position, you must ensure the following:
That no dangerous situations can occur by pushing the I/O modules into the terminal block.
You can avoid this in principle if you completely remove the I/O modules from the IO device.
Procedure
Step Procedure Illustration
1 Perform change in runtime: Read section "Removing I/O modules (Page 114)".
2 Simultaneously press the two release buttons ② on
the top and bottom of the I/O module.
3 Hold down the release buttons and pull the I/O mod‐
ule slightly (approx 3 mm) towards the front and out
of the slot ③.
Avoid pulling out an I/O module at a slanted angle.
