4.2 Mounting the product
Secure the pump to a solid foundation by bolts through the holes
in the flange or the base plate.
4.3 Cable entries
See the size of the cable entries in section 27. Other technical
data.
4.4 Ensuring motor cooling
Leave at least 2 inches (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
4.5 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 2 and 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 11.20 "Standstill heating", page 39.
Fig. 2 Examples of covers, not supplied by Grundfos
4.6 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
Ensure that the drain hole in the motor flange is open and is
facing downwards.
5. 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 grounding (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.
CAUTION

• 3 x 380-500 V - 10 %/+ 10 %, 50/60 Hz, PE
• 3 x 200-240 V - 10 %/+ 10 %, 50/60 Hz, PE.
Check that the supply voltage and frequency 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 ground (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.
For maximum backup fuse, see section 25.1 Supply voltage.
Only the following motors can be supplied through an IT network:
• Motors with speed of 1450-2000/2200 rpm and up to 2.0 HP
(1.5 kW)
• Motors with speed of 2900-4000 rpm or 4000-5900 rpm and up
to 3 HP (2.2 kW).
Fig. 6 Example of a mains-connected motor with mains
switch, backup fuses and additional protection
Fig. 7 Mains connection, three-phase motors
5.4 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 24.2 Leakage current and
25.2 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.
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 grounding is not allowed for supply voltages
above 3 x 480 V, 50/60 Hz.

6. Operating conditions
6.1 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.
6.2 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 hours on both pumps. The pumps
alternate automatically. See section 11.43 "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 11.43 "Multipump setup"
(
Setup of multi-pump system ).
6.3 Ambient temperature
6.3.1 Ambient temperature during storage and transportation
Minimum: -22 °F (-30 °C)
Maximum: 140 °F (60 °C).
6.3.2 Ambient temperature during operation
The motor can operate with the rated power output, P2, at 122 °F
(50 °C), but continuous operation at higher temperatures reduces
the expected product life. If the motor is to operate at ambient
temperatures between 122 and 140 °F (50 and 60 °C) (for 3 x
380-500 V), or 104 and 122 °F (40 and 50 °C) (for 1 x 200-230 V
or 3 x 200-240 V), select an oversized motor. Contact Grundfos
for further information.
6.4 Installation altitude
Installation altitude is the height above sea level of the installation
site. The motors can be installed up to 11,482 feet (3500 m)
above sea level.
Motors installed up to 3280 feet (1000 m) above sea level can be
loaded 100 %.
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 Supply voltage for three-phase motor in relation to
altitude
Fig. 15 Supply voltage for single-phase motor in relation to
altitude
1 x 200-230 V 3 x 200-240 V 3 x 380-500 V
Minimum -4 °F (-20 °C) -4 °F (-20 °C) -4 °F (-20 °C)
Maximum 122 °F (50 °C) 104 °F (40 °C) 122 °F (50 °C)
Motors installed more than 3280 feet (1000 m) above
sea level must not be fully loaded due to the low
density and consequent low cooling effect of the air.
