3. General description
Grundfos MGE 71-160 are frequency-controlled
permanent-magnet motors for single-phase or
three-phase mains connection. The motors
incorporate a PI controller.
You can connect the motors to a signal from an
external sensor and a setpoint signal enabling
control in closed loop. You can also use the motors
for an open-loop system in which the setpoint signal
is used as a speed control signal.
The motors are intended for machines with a square
torque characteristic, such as ventilators and
centrifugal pumps.
The motors incorporate a control panel which is
available in various versions. See section 9. User
interfaces.
Detailed motor settings are made with the wireless
Grundfos R100 remote control or Grundfos GO.
Furthermore, you can read important operating
parameters via R100 or Grundfos GO.
The motors incorporate a functional module. The
functional module is available in various versions
with different inputs and outputs. See section
7.5 Functional modules.
You can fit the motors with a Grundfos CIM module.
A CIM module is an add-on communication interface
module. The CIM module enables data transmission
between the motor and an external system, for
example a BMS or SCADA system. The CIM module
communicates via fieldbus protocols.
You can connect several MGE motors together via
radio or bus communication to create a multimotor
system.
3.1 Radio communication
This product incorporates a radio module for remote
control which is a class 1 device and which you can
use anywhere in the EU without restrictions.
For use in USA and Canada, see Installation in the
USA and Canada on page 62.
Some variants of the product and products sold in
China and Korea have no radio module.
This product can communicate with Grundfos GO
and other MGE motors of the same type via the
built-in radio module.
3.2 Battery
A Li-ion battery is fitted in the FM 300 functional
module.
The Li-ion battery complies with the Battery Directive
(2006/66/EC). The battery does not contain mercury,
lead and cadmium.

6.5 Outdoor installation
If you install the motor outdoors, provide the motor
with a suitable cover and open the drain holes to
avoid condensation on the electronic components.
See figures 4 and 5.
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
10.19 ""Standstill heating"".
Fig. 4 Examples of covers (not supplied by
Grundfos)
6.6 Drain holes
If you install the motor 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. 5 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.
7.1 Protection against electric shock,
indirect contact
Protective-earth conductors must always have a
yellow and green (PE) or yellow, green and blue
(PEN) colour marking.
7.1.1 Protection against mains voltage transients
The motor is protected against mains voltage
transients in accordance with EN 61800-3.
7.1.2 Motor protection
The motor requires no external motor protection. The
motor incorporates thermal protection against slow
overloading and blocking.
7.1.3 External switch
We recommend that you connect the motor to an
external switch.
Connect the switch via the terminals 2 (DI1) and 6
(GND). See fig. 10 (FM 100), fig. 11 (FM 200) or fig.
12 (FM 300).
Enable the ""External stop"" function. See section
10.7 "Digital inputs".
When fitting a cover to the motor, observe
the guideline in section 6.4 Ensuring motor
cooling.

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
section 23.2 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.
If you want to supply the motor through an
IT network, make sure that you have a
suitable motor variant. If you are in doubt,
contact Grundfos.
Corner earthing is not allowed for supply
voltages above 3 x 480 V, 50/60 Hz.

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
Connect three-phase motors 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 Functional modules
Various functional modules are available:
• basic functional module, FM 100
• standard functional module, FM 200
• advanced functional module, FM 300.
The selection of module depends on the application
and the required number of inputs and outputs.
7.6 Connection terminals on functional
modules
The descriptions and terminal overviews in this
section apply to both single- and three-phase
motors.
For maximum tightening torques, see section
Torques, page 60.
7.6.1 Basic functional module, FM 100
The module has only the most necessary inputs for
closed- and open-loop operation. The module also
enables communication via a GENIbus connection.
The module has these connections:
• analog voltage input
• two digital inputs or one digital input and one
open-collector output
• GENIbus connection.
See fig. 10.
• Inputs and output
The inputs and output 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.
• Mains supply (terminals N, PE, L or L1, L2, L3,
PE).
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.

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 motor
starts after approximately 5 seconds.
If a higher number of starts and stops is desired, use
the input for external start/stop when
starting/stopping the motor.
When started via an external on/off switch, the motor
starts immediately.
8.2 Ambient temperature
8.2.1 Ambient temperature during storage and
transportation
Minimum: -30 °C
Maximum: 60 °C.
8.2.2 Ambient temperature during operation
Minimum: -20 °C
Maximum: 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.
Contact Grundfos for further information.
8.3 Installation altitude
Installation altitude is the height above sea level of
the installation site.
Motors installed up to 1000 metres above sea level
can be loaded 100 %.
Motors installed more than 1000 metres above sea
level must not be fully loaded due to the low density
and consequent low cooling effect of the air. See fig.
16.
Fig. 16 Derating of motor output power (P2) in
relation to altitude above sea level
8.4 Humidity
Maximum humidity: 95 %.
If the humidity is constantly high and above 85 %,
open the drain holes in the drive-end flange. See
section 6.6 Drain holes.
8.5 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.
If the motor is installed above 2000 m, it
does not comply with the SELV/PELV
classification.
