6.5 Outdoor installation

B3 B14 B5

English (GB)

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 2 and 3.

When fitting a cover to the motor, observe
the guidelines in section 6.4 Ensuring

motor cooling.

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

In order to maintain the UL mark,
additional requirements apply to the
equipment. See page 71.

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 °.

7. Electrical installation

DANGER

Electric shock

Death or serious personal injury

- Switch off the power supply to the motor
and to the signal relays. Wait at least 5
minutes before you make any

7.4 Additional protection

DANGER

Electric shock

Death or serious personal injury

- Only use residual-current circuit
breakers (ELCB, GFCI, RCD) of type B.

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.

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.

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.

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.

8. Operating conditions

8.1 Maximum number of starts and stops

The number of starts and stops via the power supply
must not exceed four times per hour.

When switched on via the power supply, the pump
starts after approximately 5 seconds.

If a higher number of starts and stops is desired, use
the input for external start-stop when starting or
stopping the pump.

When started via an external on/off switch, the pump
starts immediately.

8.2 Alternating operation of twin-head pumps

On twin-head pumps, the duty and backup pumps
must be alternated on a regular basis, i.e. once a
week, to ensure an even distribution of the operating

TM05 3973 1812TM02 8842 0904

hours on both pumps. The pumps alternate
automatically. See section 13.43 "Multipump setup"

(Setup of multi-pump system).

If twin-head pumps are used for pumping domestic
hot water, the duty and backup pumps must be
alternated on a regular basis, i.e. once a day, to
avoid blocking of the backup pump due to deposits
such as calcareous deposits. As default, the pumps
alternate automatically. See section

13.43 "Multipump setup" (Setup of multi-pump

system).

8.3 Ambient temperature

8.3.1 Ambient temperature during storage and

transportation

Minimum: -30 °C
Maximum: 60 °C.

8.3.2 Ambient temperature during operation

3 x 200-240 V 3 x 380-500 V

Minimum -20 °C -20 °C
Maximum 40 °C 50 °C

The motor can operate with the rated power output,
P2, at 50 °C, but continuous operation at higher
temperatures reduces the expected product life. If
the motor is to operate at ambient temperatures
between 50 and 60 °C, select an oversized motor.

Installation altitude is the height above sea level of
the installation site.

Motors installed up to 1000 m above sea level can
be loaded 100 %.

The motors can be installed up to 3500 m above sea
level.

Motors 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.

Fig. 12 Motor output power in relation to altitude

In order to maintain the galvanic isolation and ensure
correct clearance according to EN 60664-1:2007,
you must adapt the supply voltage to the altitude:

8.5 Humidity

Maximum humidity: 95 %.
If the humidity is constantly high and above 85 %,

one of the drain holes in the drive-end flange must
be open. See section 6.6 Drain holes.

8.6 Motor cooling

To ensure cooling of motor and electronics, observe
the following:

• Position the motor in such a way that adequate

cooling is ensured. See section 6.4 Ensuring

motor cooling.

• The temperature of the cooling air must not

exceed 50 °C.

• Keep cooling fins and fan blades clean.

with Lightning connector, for example fifth
generation or later iPhone or iPod.
MI 204 is also available together with an
Apple iPod touch and a cover.

Grundfos MI 301:
Separate module enabling radio or infrared
communication. You can use the module in

2

conjunction with an Android or iOS-based
smart device with Bluetooth connection.

12.1 Communication

When Grundfos GO initiates communication with the
pump, the indicator light in the middle of Grundfos
Eye flashes green. See section 17. Grundfos Eye.

Furthermore, on pumps fitted with an advanced
control panel a text appears in the display saying
that a wireless device is trying to establish
connection. Press on the pump in order to
establish connection with Grundfos GO or press
to reject connection.

Establish communication using one of these
communication types:

• radio communication

• infrared communication.

12.1.1 Radio communication

Radio communication can take place at distances up
to 30 m. The first time Grundfos GO communicates
with the pump, you must enable communication by
pressing or on the pump control panel. Later
when communication takes place, the pump is

TM06 6256 0916

recognized by Grundfos GO and you can select the
pump from the "List" menu.

12.1.2 Infrared communication

When communicating via infrared light, Grundfos GO
must be pointed at the pump control panel.
