• Position the Control Panel in such a way that reflections on the screen
are avoided as far as possible.
• Use the position of the screen as a guide for the correct installation
height; it should be optimally visible for the user at all times.
• The Control Panel should not be exposed to direct sunlight.
• When the unit is in its mounting position, the ventilation openings must
not be obstructed.

on the control cabinet wall, in which the Panel is being installed.
