Installing the built-in unit
3.2.1
A high voltage may be present in the control cabinet and could cause a dangerous electric
shock.
It may result in death or serious physical injury.
Isolate the power supply to the control cabinet before opening it. Ensure that the power to
the control cabinet cannot be turned on accidentally.
If you install the device in an unapproved mounting position or if you do not observe the
ambient conditions, the device can overheat.
Overheating can cause a fire. Proper functioning of the device is no longer guaranteed.
Before you install the device, note the following general installation information.
Requirements for a fire protection enclosure according to EN 60950-1 only for standard
mounting position
In the standard mounting position and in the inclined position in horizontal format with
vertical inclination of max. ±45°, the device meets the requirements for fire protection
enclosures in accordance with EN 60950-1. It can therefore be installed without an
additional fire protection cover. For information on the mounting positions, refer to section
"Permitted mounting positions (Page 29)".
● Install the device only in one of the permitted mounting positions.
● For installation in control cabinets, note the SIMATIC setup guidelines as well as the
relevant DIN/VDE requirements or the country-specific regulations.
● Ensure that the device is classified as "Open Type" when using it in the area of Industrial
Control Equipment (UL508). A UL508 conform enclosure is therefore a mandatory
requirement for approval or operation according to UL508.
● Provide adequate volume in the control cabinet for air circulation and heat transport.
Keep at least 5 cm distance between the device and control cabinet.
● The ventilation slots of the device may not be covered or obstructed.
