6.2 Mounting
6.3 Cable entries
See the size of the cable entries in section 29. Other
technical data.
6.4 Cable glands
The number and size of cable glands delivered with
the pump depends on the motor size. See section
29. Other technical data.
6.5 Ensuring motor cooling
Leave at least 50 mm between the end of the fan
cover and a wall or other fixed objects. See fig. 1.
Fig. 1 Minimum distance (D) from the motor to
a wall or other fixed objects
6.6 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 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
13.22 Standstill heating, page 48.
Fig. 2 Examples of covers (not supplied by
Grundfos)
6.7 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
CAUTION
Crushing of feet
Minor or moderate personal injury
- Secure the product to a solid foundation
by bolts through the holes in the flange
or the base plate.
In order to maintain the UL mark,
additional requirements apply to the
equipment. See page 73.

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- and three-phase
motors.
For maximum torques, see section Torques, page
71.
7.5.1 Connection terminals, CRE, CRIE, CRNE,
SPKE and MTRE pumps
CRE, CRIE, CRNE, SPKE and MTRE pumps have a
number of inputs and outputs enabling the pumps to
be used in advanced applications where many inputs
and outputs are required.
The pumps have these connections:
• three analog inputs
• one analog output
• two dedicated digital inputs
• two configurable digital inputs or open-collector
outputs
• Grundfos Digital Sensor input and output
• 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.

English (GB)

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/stopping the pump.
When started via an external on/off switch, the pump
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
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 m above sea level can
be loaded 100 %.
The motors can be installed up to 3500 m above sea
level.
Fig. 13 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:
Fig. 14 Motor output power in relation to altitude
3 x 200-240 V 3 x 380-500 V
Minimum -20 °C -20 °C
Maximum 40 °C 50 °C
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.
