5. Mechanical installation

The individual CUE cabinet sizes are characterised by their
enclosures. The table in section 16.1 shows the relationship of
enclosure class and enclosure type.

5.1 Reception and storage

Check on receipt that the packaging is intact, and the unit is
complete. In case of damage during transport, contact the
transport company to complain.
Note that the CUE is delivered in a packaging which is not
suitable for outdoor storage.

5.2 Transportation and unpacking

The CUE must only be unpacked at the installation site to prevent
damage during the transport to the site.

5.3 Space requirements and air circulation

CUE units can be mounted side by side, but as a sufficient air
circulation is required for cooling these requirements must be
met:
• Sufficient free space above and below the CUE to allow airflow
and cable connection. See fig. 4.
• Ambient temperature up to 45 °C.
