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 function does not prevent unwanted movement from
external forces on the motor, for example, back pressure, and
the motor shaft must be covered.
Always observe local regulations concerning 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).

English (GB)

4.1 IT mains
Do not connect 380-500 V CUE frequency converters to
mains supplies with a voltage between phase and protec-
tive earth of more than 440 V.
In connection with IT mains and earthed delta mains, the mains
voltage may exceed 440 V between phase and protective earth.
4.2 Aggressive environment
CUE must not be installed in an environment where the air
contains liquids, particles or gases which may affect and
damage the electronic components.
CUE contains a large number of mechanical and electronic
components. They are all vulnerable to environmental impact.
4.3 Reduced performance under certain condition
CUE reduces its performance under the condition of low air
pressure (at high altitude).
The required measures are described in the next section.
4.3.1 Reduction at low air pressure
At altitudes above 2000 m (6600 ft), the PELV require-
ments cannot be met.
PELV = Protective Extra Low Voltage.
At low air pressure, the cooling capacity of air is reduced, and CUE
automatically reduces the performance to prevent overload.
It may be necessary to select a CUE unit with a higher
performance.
5. Mechanical installation
The individual CUE cabinet sizes are characterised by their
enclosures. The table in section Enclosure shows the relationship
between enclosure class and enclosure type.
5.1 Enclosure types
Products with integrated STO function must be installed in an IP54
cabinet according to IEC 60529 or in an equivalent environment. In
special applications, a higher IP degree may be necessary.
5.2 Location
To ensure sufficient motor and CUE cooling, leave at least 50 mm
between the end of the fan covers of both motor and CUE and a
wall or another fixed object.
6. Electrical connection
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 and that it
cannot be accidentally switched on. See Installation
requirements.
‐Touching the electrical parts may be fatal, even after
CUE has been switched off.
The owner or installer is responsible for ensuring correct
earthing and protection according to local standards.
For products with STO, ensure short-circuit protection of
the cable between terminal 37 and the external safety de-
vice.
Security measures are the responsibility of the user.
The frequency converter parameters can be password
protected.

English (GB)

6.1 Electrical protection
6.1.1 Protection against electric shock, indirect contact
CAUTION
Electric shock
Minor or moderate personal injury
‐CUE must be earthed correctly and protected against
indirect contact according to local regulations.
The leakage current to protective earth exceeds 3.5 mA,
and a reinforced earth connection is required.
Protective conductors must always have a yellow and green (PE) or
yellow, green and blue (PEN) colour marking.
Instructions according to EN IEC 61800-5-1:
• CUE must be stationary, installed permanently and connected
permanently to the mains supply.
• The protective earth connection must be carried out with
duplicate protective conductors or with a single reinforced
protective conductor with a cross-section of minimum 10 mm2.
6.1.2 Protection against short circuit, fuses
CUE and the supply system must be protected against short circuit.
Grundfos requires that the backup fuses mentioned in section
Cable cross-section to signal terminals are used for protection
against short circuit.
CUE offers complete short-circuit protection in case of a short circuit
on the motor output.
6.1.3 Additional protection
WARNING
Electric shock
Death or serious personal injury
‐The leakage current to protective earth exceeds 3.5
mA.
If CUE is connected to an electrical installation where an earth
leakage circuit breaker (ELCB/RCD) is used as additional
protection, the circuit breaker must be of a type marked with the
following symbols:
ELCB/RCD
The circuit breaker is type B.
The total leakage current of all the electrical equipment in the
installation must be taken into account.
The leakage current of CUE in normal operation can be seen in
section Electrical data.
During startup and in asymmetrical supply systems, the leakage
current can be higher than normal and may cause the ELCB/RCD
to trip.
6.1.4 Motor protection
The motor requires no external motor protection. CUE protects the
motor against thermal overloading and blocking.
6.1.5 Protection against overcurrent
CUE has an internal overcurrent protection for overload protection
on the motor output.
6.1.6 Protection against mains voltage transients
CUE is protected against mains voltage transients according to EN
61800-3, second environment.
6.2 EMC-correct installation
The motor cable must be screened for CUE to meet EMC
requirements.
This section provides guidelines for good practice when installing
CUE. Follow these guidelines to meet EN 61800-3, first
environment.
•Use only motor and signal cables with a braided metal screen in
applications without output filter.
• There are no special requirements to supply cables, apart from
local requirements.
• Leave the screen as close to the connecting terminals as
possible. See fig. Example of stripped cable with screen.
• Avoid terminating the screen by twisting the ends. See fig. Do
not twist the screen ends. Use cable clamps or EMC screwed
cable entries instead.
• Connect the screen to frame at both ends for both motor and
signal cables. See fig. Example of connection of a 3-conductor
bus cable with screen connected at both ends. If the controller
has no cable clamps, connect only the screen to the CUE
cabinet. See fig. Example of connection of a 3-conductor bus
cable with screen connected to CUE (controller with no cable
clamps).
• Avoid unscreened motor and signal cables in electrical cabinets
with frequency converters.
• Make the motor cable as short as possible in applications
without output filter to limit the noise level and minimise leakage
currents.
• Screws for frame connections must always be tightened
whether a cable is connected or not.
• Keep mains cables, motor cables and signal cables separated in
the installation if possible.
Other installation methods may give similar EMC results if the
above guidelines for good practice are followed.

to the values on the nameplate of CUE and the motor.
The motor cable must be screened for CUE to meet EMC
requirements.
The supply voltage and frequency are marked on the CUE
nameplate. Make sure that CUE is suitable for the power supply of
the installation site.
6.4.1 Main switch
A main switch can be installed before the CUE cabinet according to
local regulations. See fig. Example of three-phase mains
connection of CUE with main switch, backup fuses and additional
protection.
6.4.2 Wiring diagram
The wires in the terminal box must be as short as possible.
Excepted from this is the protective conductor which must be so
long that it is the last one to be disconnected in case the cable is
inadvertently pulled out of the cable entry.

6.5 STO installation, optional
DANGER
Exposure to high pressure or toxic liquids
Death or serious personal injury
‐Failure to remove the jumper will disable the STO
function and the motor might not stop as intended and
can cause severe injury or death.
‐Failure to use safety-monitoring relay compliant with
Category 3 /PL "d", ISO 13849-1 or SIL 2, EN 62061
and IEC 61508. Perform a functional test every 12
months to ensure that the system works properly.
To enable the integrated STO, follow these steps:
1. Remove the jumper wire between control terminals 37 and 12 or
13. Cutting or breaking the jumper is not sufficient to avoid
short-circuiting.

6.5.1 Restart behaviour after STO activation
By default the STO function is set to unintended-restart prevention
behaviour. To terminate STO and resume normal operation with
manual reset, do the following:
• Reapply 24 V DC supply to terminal 37.
• Send a reset signal via bus, Digital I/O or the reset button.
• Set the STO function to automatic restart by changing the value
of 5-19 terminal 37 "Safe Stop" from default value 1. "Safe Stop
Alarm" to value 3, "Safe Stop Warning".
Automatic restart means that STO is terminated, and normal
operation is resumed, as soon as the 24 V DC is applied to terminal
37. No reset signal is required.
6.5.2 Restart settings
• Remove the 24 V DC voltage supply to terminal 37 using the
interrupt device while the frequency converter drives the motor,
that is the mains supply is not interrupted.
• Check that the motor coasts and that the alarm Safe Stop
displays in the local operating panel if mounted.
• Reapply 24 V DC to terminal 37.
• Ensure that the motor remains in the coasted state.
• Send reset signal via bus, Digital I/O or the reset button.
• Ensure that the motor becomes operational again.
6.6 Connecting the signal terminals
As a precaution, signal cables must be separated from
other groups by reinforced insulation in their entire
lengths.
Connect the signal cables according to the guidelines for good
practice to ensure EMC-correct installation. See section Restart
behaviour after STO activation.
• Use screened signal cables with a conductor cross-section of
minimum 0.5 mm2 and maximum 1.5 mm2.
• Use a 3-conductor screened bus cable in new systems.

sensor input module
The MCB 114 is an option offering additional analog inputs for CUE.
Configuration of MCB 114
MCB 114 is equipped with three analog inputs for the following
sensors:
• One additional sensor 0/4-20 mA.
• Two Pt100/Pt1000 temperature sensors for measurement of
motor bearing temperature or an alternative temperature, such
as liquid temperature.
When MCB 114 has been installed, CUE automatically detects if the
sensor is Pt100 or Pt1000 when it is switched on.
Wiring diagram, MCB 114
When using Pt100 with a 3-wire cable, the resistance
must not exceed 30 Ω.

7. Starting up the product
Any installation, maintenance and inspection must be car-
ried out by trained persons.
Before you switch on the power supply, you must do the following:
• Close the cover.
• Ensure that all cable glands are tightened properly.
• Check that there are no loose connections on the terminals.
• Confirm that the supply voltage matches the voltage of the
frequency converter and the motor.
7.1 Switching on the product
• Confirm that the input voltage is balanced within 3 %. If not,
correct the input-voltage imbalance before proceeding. Repeat
this procedure after the voltage correction.
•Ensure that any optional equipment wiring matches the
installation application.
• Ensure that all operator devices are in the OFF position.
• Apply power to the unit, but do not start the frequency converter
yet. For units with a disconnect switch, turn it to the ON position
to apply power to the frequency converter.
7.2 Activating the optional STO function
The STO function is activated by removing the voltage at terminal
37 of the frequency converter. By connecting the frequency
converter to external safety devices providing a safe delay, an
installation for a Safe Stop 1 is obtained. External safety devices
need to fulfil Cat./PL or SIL when connected to terminal 37.
The STO function can be used for the following motor types:
• asynchronous
• synchronous
• permanent magnet motors.
When terminal 37 is activated, the frequency converter issues an
alarm, trips the unit and coasts the motor to a stop. A manual
restart is required. Use the STO function to stop the frequency
converter in emergency stop situations. In normal operating mode,
the STO terminal 37 must be deactivated to start the motor.
A successful commissioning test of the STO function is re-
quired after the initial installation and after each subse-
quent change to the installation.
