• Mounting position
To ensure air cooling in the device by convection, mount the control only vertically as shown in the
following figure.
In the shown mounting position, the natural convection supports the forced cooling air flow. Heat
pockets can thus not be caused in the device.

• End clamps
Fasten end clamps on both sides of the control.
End clamps ensure the correct fastening of the control connected to them on the mounting rail and
they are used as lateral end elements.
Always fasten the left end clamp of the station before mounting the control. This ensures the fol-
lowing:
– It impedes the shifting of the control.
– The installation place for the end clamps is secured.
•
Do not route cables parallel to motor cables or other strong interference sources to avoid the cou-
pling of interferences.
