4.2.3 Installation in the control cabinet
Preparation of the control cabinet
The control cabinet must have the required installation cutout according to the device dimensions (see
Chapter 4.2.1
Dimensions [
}
18] ) of the Control Panel.
NOTE
Extreme environmental conditions
Extreme environmental conditions can cause damage to the device.
• Avoid extreme environmental conditions.
• Protect the device against dust, moisture and heat.
Please also note the following for installation in a control cabinet:
• Position the Control Panel such that reflections from light sources on the screen are avoided as far as
possible.
• For the correct installation height, use the position of the screen for guidance. This should always be
optimally visible to the user.
• Do not expose the Control Panel to direct sunlight.
Installation in the control cabinet
Once you have made the required cutout in the control cabinet, you can install the Control Panel in the
control cabinet. Clamping levers are provided at the back of the housing for final mounting of the device.
To install and secure the Control Panel in the control cabinet, follow the steps shown in Fig. 17:
1. Insert the Control Panel at the intended position in the panel of the control cabinet. Make sure that the
device is secured against falling out until it is fastened properly.
2. Loosen the clamping levers with a 3.0 mm Allen key (sections A and B).
3. Fold out the clamping levers 90° (section C).
4. Retighten the clamping levers with the Allen key (section D).
4.3 Connecting the Control Panel
CAUTION
Risk of electric shock
Dangerous touch voltages can lead to electric shock. To avoid electric shock, observe the following:
• Never connect or disconnect the device cables during a thunderstorm.
• Provide protective earthing for handling the device.
To prepare the Control Panel for operation, you have to connect it. The first step is to ground the device.
Then you can connect the cables and the power supply.
An external power supply unit is required to supply 24 V DC (-15 %/+20 %) for operating the device.
Connect the Control Panel in the control cabinet according to standard EN 60204-1:2006 Protective Extra
Low Voltage (PELV):
• The PE conductor (protective earth) and the "0 V" conductor of the voltage source must be on the
same potential (connected in the control cabinet).
• Standard EN 60204-1:2006, section 6.4.1:b stipulates that one side of the circuit, or a point of the
energy source for this circuit must be connected to the protective earth conductor system.
Devices connected to the Control Panel with their own power supply must have the same potential for the
PE "0 V" conductors as the Control Panel (no potential difference).
