4.4.1 Reduction at low air pressure
PELV = Protective Extra Low Voltage.
At low air pressure, the cooling capacity of air is reduced, and the
CUE automatically reduces the performance to prevent overload.
It may be necessary to select a CUE with a higher performance.
4.4.2 Reduction in connection with long motor cables
The maximum cable length for the CUE is 1000 ft. (300 m) for
unscreened and 500 ft. (150 m) for screened cables. In case of
longer cables, contact Grundfos.
The CUE is designed for a motor cable with a maximum gauge
size as stated in section 17.6 Fuses and cable gauge size.
5. Identification
5.1 Nameplate
The CUE can be identified by means of the nameplate.
An example is shown below.
Fig. 1 Example of nameplate
5.2 Packaging label
The CUE can also be identified by means of the label on the
packaging.
6. Mechanical installation
The individual CUE cabinet sizes are characterized by their
enclosures. The table in section 17.1 Enclosure shows the
relationship between enclosure class and enclosure type.
6.1 Receipt 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 packaging which is not suitable
for outdoor storage.
6.2 Transportation and unpacking
To prevent damage during the transport to the site, the CUE must
only be unpacked at the installation site.
The packaging contains accessory bag(s), documentation and
the unit itself. See fig. 2.

Warning
At altitudes above 6600 ft. (2000 m), the PELV
requirements cannot be met.
