Installation requirements
Safety regulations
• The OFF button of the operating panel does not disconnect
CUE from the power supply and must therefore not be used as
a safety switch.
• CUE must be earthed correctly and protected against indirect
contact according to local regulations.
• The leakage current to protective earth exceeds 3.5 mA.
• Enclosure class IP20/21 must not be installed freely
accessible, but only in a panel.
• Enclosure class IP54/55 must not be installed outdoors
without additional protection against weather conditions and
the sun.
• The STO function does not disconnect CUE from the power
supply and must therefore not be used as a safety switch.
• The STO does not prevent unwanted movement from external
forces on the motor, for example, back pressure, and motor
shaft must be covered.
Always observe local regulations as to cable cross-section,
short-circuit protection and overcurrent protection.
The general safety necessitates special considerations as to
these aspects:
• fuses and switches for overcurrent and short-circuit protection
• selection of cables (mains current, motor, load distribution and
relay)
• net configuration (IT, TN, earthing) safety on connecting inputs
and outputs (PELV).
IT mains
In connection with IT mains and earthed delta mains, the mains
voltage may exceed 440 V between phase and earth.
WARNING
Heavy dumping
Death or serious personal injury
- Make sure that the pump remains
in a stable position during
unpacking and installation by
means of the straps used for
lifting the pump.
- Note that typically the centre of
gravity of the pump is close to the
motor.

WARNING
Electric shock
Death or serious personal injury
- Before starting any work on the
product, make sure that the
power supply has been switched
off at least for as long as stated
below and that it cannot be
accidentally switched on.
- Touching the electrical parts may
be fatal, even after CUE has been
switched off.
Do not connect 380-500 V CUE
frequency converters to mains
supplies with a voltage between
phase and earth of more than
440 V.
