lifting or handling. The motor weight is stated on the
nameplate.
6.2 Mounting the product
Secure the pump to a solid foundation by bolts
through the holes in the flange or the base plate.
6.3 Cable entries
See the size of the cable entries in section 29. Other
technical data.

6.5 Outdoor installation
If you install the motor outdoors, provide the motor
with a cover and open the drain holes to avoid
condensation on the electronic components. See
figures 2and 3.
The cover must be sufficiently large to ensure that
the motor is not exposed to direct sunlight, rain or
snow. Grundfos does not supply covers. We
therefore recommend that you have a cover built for
the specific application. In areas with high humidity,
we recommend that you connect the motor
permanently to the mains supply and activate the
built-in standstill heating function. See section
13.20 "Standstill heating", page 44.
Fig. 2 Examples of covers, not supplied by
Grundfos
6.6 Drain holes
When the motor is installed in moist surroundings or
areas with high humidity, the bottom drain hole must
be open. The enclosure class of the motor will then
be lower. This helps prevent condensation in the
motor as the motor becomes self-venting, and it
allows water and humid air to escape.
The motor has a plugged drain hole on the drive
side. You can turn the flange 90 ° to both sides or
180 °.
Fig. 3 Drain holes
7. Electrical installation
If the power supply cable is damaged, it must be
replaced by the manufacturer, the manufacturer's
service partner or a similarly qualified person.
The user or the installer is responsible for the
installation of correct earthing and protection
according to local regulations. All operations must be
carried out by a qualified electrician.
Carry out the electrical connection according to local
regulations.
Check that the supply voltage and frequency
correspond to the values stated on the nameplate.
When fitting a cover to the motor, observe
the guidelines in section 6.4 Ensuring
motor cooling.

correspond to the values stated on the nameplate.
The wires in the motor terminal box must be as short
as possible. Excepted from this is the separated
earth 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.
In order to avoid loose connections, ensure that the
terminal block for L1, L2 and L3 is pressed home in
its socket when the supply cable has been
connected.

voltage.
Only the following motors can be supplied through
an IT network:
• Motors with speed of 1450-2000/2200 rpm and
up to 1.5 kW

7.4 Additional protection
The residual-current circuit breaker must be marked
with the following symbol:
The total leakage current of all the electrical
equipment in the installation must be taken into
account. You find the leakage current of the motor in
sections 26.2 Leakage current and 27.2 Leakage
current, AC.
This product can cause a direct current in the
protective earth conductor.
Overvoltage and undervoltage protection
Overvoltage and undervoltage may occur in case of
unstable power supply or a faulty installation. The
motor is stopped if the voltage falls outside the
permissible voltage range. The motor restarts
automatically when the voltage is again within the
permissible voltage range. Therefore, no additional
protection relay is required.
Overload protection
If the upper load limit is exceeded, the motor
automatically compensates for this by reducing the
speed and stops if the overload condition persists.
The motor remains stopped for a set period. After
this period, the motor automatically attempts to
restart. The overload protection prevents damage to
the motor. Consequently, no additional motor
protection is required.
Overtemperature protection
The electronic unit has a built-in temperature sensor
as an additional protection. When the temperature
rises above a certain level, the motor automatically
compensates for this by reducing the speed and
stops if the temperature keeps rising. The motor
remains stopped for a set period. After this period,
the motor automatically attempts to restart.
Protection against phase unbalance
Three-phase motors must be connected to a power
supply with a quality corresponding to IEC
60146-1-1, class C, to ensure correct motor
operation at phase unbalance. This also ensures
long life of the components.
7.5 Connection terminals
The descriptions and terminal overviews in this
section apply to both single-phase and three-phase
motors.
For maximum torques, see section 29.1 Torques.
7.5.1 Connection terminals, advanced functional
module, FM 300
The advanced module has these connections:
• three analog inputs
• one analog output
• two dedicated digital inputs
• two configurable digital inputs or open-collector
outputs
• Input and output for Grundfos Digital Sensor
Not applicable for TPE, TPED, NBE, NBGE, NKE
and NKGE pumps. The factory-fitted
differential-pressure sensor for TPE, TPED, NBE,
NKE Series 2000 is connected to this input.
• two Pt100/1000 inputs
• two LiqTec sensor inputs
• two signal relay outputs
• GENIbus connection.
See fig. 8.
DANGER
Electric shock
Death or serious personal injury
- Only use residual-current circuit
breakers (ELCB, GFCI, RCD) of type B.
The motor is protected against transients
from the power supply according to EN
61800-3. In areas with high lightning
intensity, we recommend external lightning
protection. Digital input 1 is factory-set to be start-stop
input where open circuit results in stop. A
jumper has been factory-fitted between
terminals 2 and 6. Remove the jumper if
digital input 1 is to be used as external
start-stop or any other external function.
DANGER
Electric shock
Death or serious personal injury
- Make sure that the wires to be
connected to the connection groups
below are separated from each other by
reinforced insulation in their entire
lengths.

English (GB)

•Inputs and outputs
All inputs and outputs are internally separated
from the mains-conducting parts by reinforced
insulation and galvanically separated from other
circuits.
All control terminals are supplied by protective
extra-low voltage, PELV, thus ensuring protection
against electric shock.
•Signal relay outputs
– Signal relay 1:
LIVE:
You can connect supply voltages up to 250
VAC.
PELV:
The output is galvanically separated from
other circuits. Therefore, you can connect the
supply voltage or protective extra-low voltage
to the output as desired.
– Signal relay 2:
PELV:
The output is galvanically separated from
other circuits. Therefore, you can connect the
supply voltage or protective extra-low voltage
to the output as desired.
• Mains supply, terminals N, PE, L or L1, L2, L3,
PE.
* If you use an external supply source, make sure
that there is a connection to GND.
