during lifting operations.
‐Follow the lifting instructions for the
product.
WARNING
Back injury
Death or serious personal injury
‐Use lifting equipment and follow local
regulations when lifting the product.
Observe local regulations concerning limits
for manual lifting or handling. Calculate the
total weight of the pump with motor by
adding the weights stated on the pump
and motor nameplates.
Do not lift the product by the terminal box.
Note that typically the center of gravity of
the pump is close to the motor.
For lifting instructions, see the related
installation and operating instructions for
the pump.
5.1 Installing the product outdoors or in areas
with high humidity
WARNING
Fire hazard
Death or serious personal injury
‐In high humidity environments where
condensation can occur, connect the
product permanently to the mains
supply and activate the standstill
heating function.
To maintain the cURus mark, additional
requirements apply to the equipment. See
the appendix concerning installation in the
USA and Canada.
Do not expose the product to UV radiation.
If you install the product outdoors or in areas with a
high humidity, take the following action to avoid
condensation on the electronic components.
• Provide the product with a suitable cover.
The cover must be large enough to ensure that
the product is not exposed to direct sunlight, UV
radiation, rain or snow. Grundfos does not supply
covers.
When fitting a cover to the product,
observe the instructions for adequate
cooling.
TM053496
• Open the drain holes in the product.
When you open the drain hole, the
enclosure class of the motor will be
lower than standard.
• Connect the product permanently to the mains
supply. In areas with a high humidity, activate the
built-in standstill heating function.
8
English (GB)

If you install the motor in moist
surroundings or areas with a high humidity,
ensure that the bottom drain hole is open.
As a result, the motor becomes self-
venting, allowing water and humid air to
escape. When you open the drain hole,
the enclosure class of the motor will be
lower than standard.
5.3.1 Cooling the motor
• Install the motor allowing a distance of minimum
50 mm (D) between the end of the fan cover and
the wall or another fixed object.
D
TM082853

7.7.5 Three-phase connections
The cables in the terminal box must be as short as
possible. However, the separated protective-earth
conductor 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.
To maintain the cURus mark, additional
requirements apply to the equipment. See
the appendix concerning installation in the
USA and Canada.
Model K: To avoid loose connections, ring terminals
must be used. Ensure that ring terminals are short
enough to stay within the terminal cover.

‐This product can cause a DC current in
the protective-earth conductor. If a
residual current-operated protective
(RCD) or monitoring (RCM) device is
used for protection in case of direct or
indirect contact, only an RCD or RCM
of Type B is allowed on the supply side
of this product.
The residual-current circuit breaker must be marked.

7.8.2 Overvoltage and undervoltage protection
Overvoltage and undervoltage may occur in case of
unstable power supply or a faulty installation. The
product stops if the voltage falls outside the
permissible voltage range. The product restarts
automatically when the voltage is within the
permissible voltage range. The product requires no
additional protection relay.
The product is protected against transients
from the power supply according to EN
61800-3. In areas with high lightning
intensity, we recommend external lightning
protection.
Overvoltage category:
The product is approved for Overvoltage category III
rating.
7.8.3 Overload protection
The motor-current protection settings are fixed for
each motor variants. The settings ensure that the
motor is protected against overtemperature in all
operating states with regard to supply voltage and
shaft load, including a blocked shaft.
The motors are current controlled and will respond by
reducing the speed if the shaft load increases more
than 10 % of the nominal load.
If the shaft load forces the speed down to minimum
speed, the motor shuts down.
A sudden increase in the motor current caused by a
fault where the peak of the motor current is increased
60 % above nominal will cause the motor to shut
down within 0.5 ms.
The product requires no additional protection.
7.8.4 Overtemperature protection
The motor is thermally protected by a temperature
measurement in the drive. It can handle the lack of
airflow over the motor in case the fan cover is
blocked. It also means that the protection has a built-
in memory retention.
The time from start to shutdown due to
overtemperature is therefore always longer when
starting at a motor temperature close to the ambient
temperature compared with restarting after a
shutdown due to overtemperature.
7.8.5 Protection against phase unbalance
Phase unbalance on the power supply must be
minimised. The three-phase motor must be
connected to a power supply with a quality
corresponding to IEC 60146-1-1, class C. This also
ensures long life of the components.
7.8.6 Short-circuit current
The product's electronic power output short-circuit
protection circuitry meets the requirements of IEC
60364-4-41:2005/AMD1:-, Clause 411.
Model K: Suitable for use on a circuit capable of
delivering not more than 5000 rms symmetrical
amperes, 400 V maximum when protected by gG
fuses. See the section on fuse sizes.

11.1.1 Cleaning the product
WARNING
Electric shock
Death or serious personal injury
‐Switch off the power supply to the
product including the power supply for
the signal relays. Make sure that the
power supply cannot be switched on
accidentally.
‐Check that the terminal box cover is
intact before spraying water or
chemicals on the product.
‐Cleaning must be done with non-
aggressive materials to avoid damage
to surfaces and labels.
‐Make sure that the air inlets are kept
clean and free of residuals.
Do not expose the product to high-
pressure water jets.
To clean the motor, follow the procedure below:
1. Let the motor cool down first to avoid
condensation.
2. Spray it with cold water, and use only non-
aggressive cleaning materials.
12. Taking the product out of operation
WARNING
Electric shock
Death or serious personal injury
‐Switch off the power supply and make
sure that it cannot be accidentally
switched on. The power supply must
be switched off for at least five minutes
before you start working on the
product.
WARNING
Back injury
Death or serious personal injury
‐Use lifting equipment and follow local
regulations when lifting the product.
The lifting eyes on the motor can be used
for lifting the pump as well.
For lifting instructions, see the related
installation and operating instructions for
the pump.
13. Fault finding
WARNING
Electric shock
Death or serious personal injury
‐Switch off the power supply before you
start any work on the product.
‐Make sure that the power supply
cannot be switched on accidentally.
For information on fault finding,
see the related installation and operating
instructions for the pump.
14.1.1 Installation altitude
The installation altitude is the height above sea level
of the installation site.
Products installed up to 1000 m above sea level can
be loaded 100 %.
The motors can be installed up to 3500 m above sea
level.
Products installed more than 1000 m
above sea level must not be fully loaded
due to the low density and consequent low
cooling effect of the air.
The motor output power (P2) in relation to the altitude
above sea level is shown in the graph.

14.1.4 Humidity
Description Percentage
Maximum humidity (non-condensing) 95 %
If the humidity is constantly high and above 85 %,
open the drain holes in the drive-end flange to vent
the motor.
If you install the motor in moist
surroundings or areas with high humidity,
ensure that the bottom drain hole is open.
As a result, the motor becomes self-
venting, allowing water and humid air to
escape. When you open the drain hole,
the enclosure class of the motor will be
lower than standard.
14.1.5 Pollution degree
The product is approved for Pollution degree 3 rating.

14.2.1 Leakage current (AC)
The leakage currents are measured without any load
on the shaft and in accordance with EN
61800-5-1:2007.
WARNING
Electric shock
Death or serious personal injury
‐If the leakage current is greater than
3.5 mA, use a PE cable with a
minimum cross-section of at least 10
mm2, or use 2 separate PE cables with
the same cross section as the power
cable.
