5.1 Enclosure types
Products with integrated STO function must be installed in an IP54
cabinet according to IEC 60529 or in an equivalent environment. In
special applications, a higher IP degree may be necessary.
5.2 Space requirements and air circulation
The CUE units can be mounted side by side, but as sufficient air
circulation is required for cooling, these requirements must be met:
•
Sufficient free space above and below the CUE cabinet. See the
table below.
•
Ambient temperature up to 50 °C (122 °F).
•
The CUE cabinet must be hung directly on the wall or fitted with
a back plate.
