Mounting
4 Mounting
The Control Panel CP29xx is designed for mounting in control cabinets in machine and plant engineering
applications. The ambient conditions specified for operation must be observed (see chapter
Technical
Data ).
4.1 Installation in the control cabinet
4.1.1 Preparation of the control cabinet
The control cabinet wall must be prepared with the required mounting opening according to the Control
Panel’s dimensions (see chapter
Assembly dimensions ).
Circulation of air
Note
When the unit is installed in an enclosure, adequate space for ventilation must be
provided.
The clearance above and below the housing must be at least 5 cm in order to ensure
adequate ventilation of the Control Panel.
Please note the following points during installation of the Control Panel:
• 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.
Avoid extreme environmental conditions
Attention
Extreme environmental conditions should be avoided as far as possible. Protect the
Control Panel from dust, moisture and heat.
The ventilation slots of the Control Panel must not be covered.
4.1.2 Installation in a control cabinet wall
For installation of the Control Panel proceed as follows:
1. Insert the Control Panel at the intended control cabinet wall position and protect it from falling out,
prior to final mounting.
2. Release the clamping levers, turn the clamping levers to the side and retighten the screws (see
chapter Mounting of the Control Panel ).
4.1.3 Earthing measures
Earthing connections dissipate interference from external power supply cables, signal cables or cables to
peripheral equipment. Establish a low-impedance connection from the earthing point on the Control Panel
housing (see chapter
Ground connection ) to the central earthing point on the control cabinet wall, in
which the Panel is being installed.
Malfunction possible with missing ground connection
Note
A proper ground connection of the device is absolutely necessary for the correct
function of the touchscreen.
