To install the new module, proceed in reverse order. After
installing/exchanging an expansion module, the retainers may need to be
readjusted. To do this, proceed as follows:
Caution
!

down or force the retainers in any way.

Disconnect all mains connections to the module.
Undo the screw which fastens the expansion module to the side of the
system box.
Pull the module carefully out of the slot – without tilting it.
Set the DIP switches and jumpers of the new module according to the old
module (providing that the release levels of the two modules correspond,
if the release levels are not the same, you must consult the relevant
module documentation).
Insert the sliding element at the top and push it down until it covers the
module. Then guide the module into the notch.
Detach the part of the sliding element which juts out by scratching a
notch in the top of the sliding element with a knife and then bending it
over to break it off.
