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.
When fitting a cover to the motor, observe
the guidelines in section 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 "Standstill heating".

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°.

7.4 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
the sections on leakage current and 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.

7.6 Signal cables
• Use screened cables with a cross-sectional area
of minimum 0.5 mm2 and maximum 1.5 mm2 for
external on/off switch, digital inputs, setpoint and
sensor signals.
• Connect the screens of the cables to frame at
both ends with good connection. The screens
must be as close as possible to the terminals.
TM021325
Stripped cable with screen and wire connections
• Always tighten screws for frame connections
whether a cable is fitted or not.
• The wires in the motor terminal box must be as
short as possible.
7.7 Bus connection cable
7.7.1 New installations
For the bus connection, use a screened 3-core cable
with a cross-sectional area of minimum 0.5 mm2 and
maximum 1.5 mm2.
If the motor is connected to a unit with a cable clamp
which is identical to the one on the motor, connect the
screen to this cable clamp.
If the unit has no cable clamp, leave the screen
unconnected at this end.

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
hours on both pumps. The pumps alternate
automatically. See section "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 "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. Contact
Grundfos for further information.
8.4 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.
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.
