Step Action
1 Select the snap-out opening on the front of the Push Button Panel
in which the 22.5 mm element is to be inserted.

middle of the selected snap-out opening. Use a sharp knife to slit
the foil.

3 Cut the foil corresponding to outer circumference
Ë
of the
selected snap-out opening. The round piece of foil, in whose place
the 22.5 mm element is to be inserted, is only connected to the
remaining foil above the three metal bars
Ì
.
Note:
Ensure that the foil on the front side of the Push Button Panel is
only cut in the area of the snap-out opening. In this way, the de-
gree of protection of the front surface is retained after the 22.5 mm
element has been installed.
4 Insert a screwdriver or similarly appropriate tool from the rear
through the elongated hole
Ê
in the middle of the selected snap-
out hole. Use the screwdriver to lever the metal piece out where
the 22.5 mm element is to be inserted.
5 Cut the foil corresponding to the opening which appears in the
front section of the Push Button Panel.
6 Insert the 22.5 mm element in the opening in the front of the Push
Button Panel.
The basis for interference-free operation is EMC hardware design of the PLC
and the use of interference-proof cables. The guidelines on the interference-
free design of the PLC apply equally to the installation of the Push Button
Panel.
