2.1 General description
23
The CUE is a series of external variable frequency drives
24
especially designed for pumps.
28
Thanks to the start-up guide in the CUE, the installer can quickly
28
set central parameters and put the CUE into operation.
29
Connected to a sensor or an external control signal, the CUE will
31
quickly adapt the pump speed to the actual demand.

2.2 Applications
39
The CUE series and Grundfos standard pumps are a supplement
to the Grundfos E-pumps range with integrated variable
39
frequency drive.
39
A CUE solution offers the same E-pump functionality
39
•
in the supply voltage or power ranges not covered by the
39
E-pump range.
40
40
•
in applications where an integrated variable frequency drive is
not desirable or permissible.
