Mounting and connecting the device
3.2 Installing the built-in unit
Risk of fire
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 38)".
● 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.
● Ensure there is enough clearance in the control cabinet to allow the backplane cover to
be removed.
● Equip the control cabinet with struts for stabilizing the mounting cut-out. Install struts
where necessary.
