9.1 Introduction
This manual introduces all aspects of your Grundfos CUE
variable frequency drive in the output current range of 1.8 to
177 A.
Always keep this manual close to the CUE.
9.2 General description
The CUE is a series of external variable frequency drives
especially designed for pumps.
Thanks to the start-up guide in the CUE, the installer can quickly
set central parameters and put the CUE into operation.
Connected to a sensor or an external control signal, the CUE will
quickly adapt the pump speed to the actual demand.
9.3 Applications
The CUE series and Grundfos standard pumps are a supplement
to the Grundfos E-pumps range with integrated variable
frequency drive.
A CUE solution offers the same E-pump functionality
•
in the supply voltage or power ranges not covered by the
E-pump range.
•
in applications where an integrated variable frequency drive is
not desirable or permissible.
Warning
Prior to installation, read these installation and
operating instructions. Installation and operation
must comply with local regulations and accepted
codes of good practice.
Warning
If these safety instructions are not observed,
it may result in personal injury!
Caution
If these safety instructions are not observed,
it may result in malfunction or damage to the
equipment!
Note
Notes or instructions that make the job easier
and ensure safe operation.
