Mounting the device
3.1 Preparing for installation
In the following, all of these mounting options are referred to by the general term "cabinet".
The HMI device is self-ventilated and approved for inclined mounting at angles of up to +/-
35° in stationary cabinets.
NOTICE
Damage due to overheating
An inclined installation reduces the convection by the HMI device and therefore the
maximum permitted ambient temperature for operation.
If there is sufficient convection from forced ventilation, the HMI device can also be operated
in the inclined mounting position up to the maximum permitted ambient temperature for
vertical installation. The HMI device may otherwise be damaged and its certifications and
warranty will be void.
Note
Extended inclination and ambient temperature range
You can operate the 9" and 12" devices with extended inclination and extended temperature
range under the following conditions:
• The USB load does not exceed 100 mA per USB port.
• The +24 V DC connection of the PROFIBUS interface is not used.
The following mounting positions and temperature ranges are permitted under the specified
conditions:
• Vertical mounting in landscape format with a maximum ambient temperature of +50 °C
• Mounting in landscape format with an inclination of up to 40° from the vertical with a
maximum ambient temperature of 40 °C
For information regarding the permitted ambient temperatures, refer to section "Climatic
ambient conditions (Page 38)".
