4.3 Liquid temperatures/cooling
The maximum liquid temperature and the minimum
flow velocity past the motor appear from the
following table.
Grundfos recommends installing the motor above the
well screen in order to achieve proper motor cooling
via liquid passing the motor.
If there is a risk of sediment build-up, such as sand,
around the motor, a flow sleeve should be used in
order to ensure proper cooling of the motor.
* At an ambient pressure of minimum 1 bar (0.1 MPa).
** At an ambient pressure of minimum 2 bar (0.2 MPa).
Note
If the stated flow velocity cannot be
achieved in the borehole, a flow sleeve
must be installed.

5. Electrical connection
5.1 General
The electrical connection must be carried out by an
authorised electrician in accordance with local
regulations.
The supply voltage, rated maximum current and cos
φ appear from the separate nameplate that must be
fitted close to the installation site.
The required voltage quality for Grundfos MS and
MMS submersible motors, measured at the motor
terminals, is - 10 %/+ 6 % of the nominal voltage
during continuous operation (including variation in
the mains voltage and losses in cables).
Furthermore, check that there is voltage symmetry in
the power supply lines, i.e. same difference of
voltage between the individual phases. See also
section 10. Checking the motor and cable, item 2.
If MS motors with a built-in temperature transmitter
(Tempcon) are not installed together with an MP 204
motor protection unit, they must be connected to a
0.47 μF capacitor approved for phase-phase
operation (IEC 384-14) to meet the EC EMC
directive (2004/108/EC). The capacitor must be
connected to the two phases to which the
temperature transmitter is connected. See fig. 6.
Fig. 6 Connection of capacitor
The motors are wound for direct-on-line starting or
star-delta starting, and the starting current is
between four and six times the rated current of the
motor.
The run-up time of the motor is only about 0.1
second. Direct-on-line starting is therefore normally
approved by the power supply company.
5.1.1 Frequency converter operation
Three-phase MS motors can be connected to a
frequency converter.
MMS motors with PE/PA can be connected to a
frequency converter.
Warning
Before starting work on the product, switch
off the power supply. Make sure that the
power supply cannot be accidentally
switched on.
Warning
The motor must be earthed.
The motor must be connected to an
external mains switch with a minimum
contact gap of 3 mm in all poles.
TM00 7100 0696
Caution
If an MS motor with temperature
transmitter is connected to a frequency
converter, a fuse incorporated in the
transmitter will melt and the transmitter will
be inactive. The transmitter cannot be
reactivated. This means that the motor will
operate like a motor without a temperature
transmitter.

2 = L2: Black
3 = L3: Grey
4 = PE: Yellow and green
English (GB)
11
If a temperature transmitter is required, a Pt100
sensor for fitting to the submersible motor can be
ordered from Grundfos.
To avoid damage to the pump part, make sure that
the motor stops when the pump flow falls below 0.1 x
rated flow.
Depending on the type, the frequency converter may
cause increased acoustic noise from the motor.
Furthermore, it may expose the motor to detrimental
voltage peaks.
This can be avoided by installing a correctly
dimensioned sinus filter between the frequency
converter and the motor.
Grundfos recommends installing a sinus filter when a
frequency converter is used.
Voltage peaks for Grundfos submersible motors
should be limited in accordance with the table below.
Permissible frequency ranges: 30-50 Hz and 30-60
Hz.
Ramp times: Maximum 3 seconds for start and stop.
5.2 Motor protection
5.2.1 Single-phase motors
Single-phase MS 402 submersible motors
incorporate a thermal switch and require no
additional motor protection. As a exception, the 1.1
kW (1.5 hp) MS 402 requires external current
protection.
Single-phase MS 4000 / MS 6000 submersible
motors must be protected. A protective device can
either be incorporated in a control box or be
separate.
5.2.2 Three-phase motors
MS motors are available with or without a built-in
temperature transmitter.
Motors with a built-in and operational temperature
transmitter must be protected by:
a motor-protective circuit breaker with thermal
relay or
an MP 204 motor protection unit and
contactor(s).
Motors with or without a non-operational temperature
transmitter must be protected by:
a motor-protective circuit breaker with thermal
relay or
an MP 204 motor protection unit and
contactor(s).
MMS motors have no built-in temperature
transmitter. A Pt100 sensor is available as an
accessory.
Motors with a Pt100 sensor must be protected by the
following:
a motor-protective circuit breaker with thermal
relay or
an MP 204 motor protection unit and
contactor(s).
Motors without a Pt100 sensor must be protected by
the following:
a motor-protective circuit breaker with thermal
relay with max. trip class 10 according to
IEC 60947-4-1 or
an MP 204 motor protection unit and
contactor(s).
Caution
During frequency converter operation, it is
not advisable to run the motor at a
frequency higher than the rated frequency
(50 or 60 Hz). In connection with pump
operation, it is important never to reduce
the frequency (and consequently the
speed) to such a level that the necessary
flow of cooling liquid past the motor is no
longer ensured.

Note
To enable monitoring of the motor
temperature when running at frequency
converter operation, Grundfos
recommends installing a Pt100 sensor
together with a PR 5714 relay.
Warning
When the motor has been thermally
switched off, the motor terminals are still
live. When the motor has cooled
sufficiently, it will restart automatically.
English (GB)

5.2.3 Required settings of the motor-protective
circuit breaker
For motors with an MP 204 motor protection unit,
Grundfos recommends using a special trip curve with
P-characteristics at a setting of Un times 5 for 1
second.
For cold motors, the tripping time for the motor-
protective circuit breaker must be less than 10
seconds at five times the rated maximum current of
the motor.
For all Grundfos submersible MMS motors, the
maximum start and stop ramp time is 3 seconds
(minimum 30 Hz).
In order to ensure optimum protection of the
submersible motor, set the motor-protective circuit
breaker in accordance with the following guidelines:
1. Set the overload to the rated maximum current of
the motor.
2. Start the motor and let it run for half an hour at
normal performance.
3. Slowly grade down the scale indicator until the
motor trip point is reached.
4. Increase the overload setting by 5 %.
The highest permissible setting is the rated
maximum current of the motor.
For motors wound for star-delta starting, set the
motor-protective circuit breaker as above, but the
maximum setting must be rated maximum current x
0.58.
The highest permissible startup time for star-delta
starting or autotransformer starting is 2 seconds.
5.3 Lightning protection
The installation can be fitted with a special
overvoltage protection device to protect the motor
from voltage surges in the power supply lines if
lightning strikes somewhere in the area. See fig. 7.
Fig. 7 Connecting an overvoltage protection
device
The overvoltage protection device will not, however,
protect the motor against a direct stroke of lightning.
Connect the overvoltage protection device to the
installation as close as possible to the motor and
always in accordance with local regulations. Ask
Grundfos for lightning protection devices.
MS 402 submersible motors, however, require no
further lightning protection as they are highly
insulated.
Ask for a special cable termination kit with a built-in
overvoltage protection device for Grundfos 4"
submersible motors (product no. 799911/799912).
5.4 Cable sizing
Make sure that the submersible drop cable can
withstand permanent submersion in the actual liquid
and at the actual temperature.
The cross-section (q) of the cable must meet the
following requirements:
The submersible drop cable must be sized to the
rated maximum current of the motor.
The cross-section must be sufficient to make a
voltage drop over the cable acceptable.
Grundfos supplies submersible drop cables for a
wide range of installations. For correct cable sizing,
Grundfos offers a cable sizing tool.
Fig. 8 Cable sizing tool
The sizing tool provides a accurate calculation of the
voltage drop at a given cross-section on the basis of
the following parameters:
cable length
operating voltage
full-load current
power factor
ambient temperature.
Caution
If this requirement is not met, the motor
warranty will be invalidated.

Caution
Submersible motor cables are
dimensioned for submersion in the liquid,
and will not necessarily have sufficient
cross-section to be in air.
TM05 8770 2613
English (GB)
13
The voltage drop can be calculated both for direct-
on-line and star-delta starting.
In order to minimise operating losses, the cable
cross-section may be increased. This is only cost-
efficient if the borehole provides the necessary
space, and if the operating time of the pump is long.
The cable sizing tool also provides a power loss
calculator that shows the potential savings of an
increased cross-section.
As an alternative to the cable sizing tool, select the
cross-section on the basis of the current values of
the given cables.
The cross-section of the submersible drop cable
must be large enough to meet the voltage quality
requirements specified in section 5.1 General.
Determine the voltage drop for the cross-section of
the submersible drop cable by means of the
diagrams on pages 40 and 41.
Use the following formula:
I: Rated maximum current of the motor.
For star-delta starting, I is equal to the rated
maximum current of the motor x 0.58.
Lx: Length of cable converted to a voltage drop of 1
% of the nominal voltage.
q: Cross-section of submersible drop cable.
Draw a straight line between the actual I-value and
the Lx-value. Where the line intersects the q-axis,
select the cross-section that lies right above the
intersection.
The diagrams are made on the basis of the formulas:

5.6.4 Checking the direction of rotation
When the motor has been connected to the power
supply, determine the correct direction of rotation as
follows:
1. Add a few drops of water to the shaft seal before
starting.
2. Start the motor and check the direction of rotation
by watching the motor shaft. For Grundfos SP
pumps, the direction of rotation must be counter-
clockwise.
3. Compare the result from item 1 with the demand
of the pump.
4. Interchange two of the phase connections if the
direction of rotation is wrong. In the case of
motors wound for star-delta starting, exchange
U1 by V1 and U2 by V2
5.7 Connection of three-phase motors
5.7.1 Motors wound for direct-on-line starting

5.7.3 Connection in the case of unidentified cable
marking/connection
If it is unknown where the individual leads are to be
connected to the mains in order to ensure the correct
direction of rotation, proceed as follows:
Motors wound for direct-on-line starting
Connect the motor to the mains as is expected to be
right.
Then check the direction of rotation as described in
section 5.6.4 Checking the direction of rotation.
Motors wound for star-delta starting
Determine the windings of the motor by means of an
ohmmeter, and name the lead sets for the individual
windings accordingly: U1-U2, V1-V2, W1-W2. See
fig. 16.
Fig. 16 Unidentified cable marking/connection -
motors wound for star-delta starting
If star-delta starting is required, connect the leads as
shown in fig. 14.
If direct-on-line starting is required, connect the
leads as shown in fig. 15.
Then check the direction of rotation as described in
section 5.6.4 Checking the direction of rotation.
5.7.4 Soft starter
Grundfos only recommends the use of soft starters
which control the voltage on all three phases and
which are provided with a bypass contact.
Ramp times: Maximum 3 seconds.
For further details, please contact your soft starter
supplier or Grundfos.
5.7.5 Frequency converter
Three-phase MS submersible motors can be
connected to a frequency converter.
Permissible frequency ranges: 30-50 Hz and 30-60
Hz.
Ramp times: Maximum 3 seconds for start and stop.
Depending on the type, the frequency converter may
cause increased acoustic noise from the motor.
Furthermore, it may expose the motor to detrimental
voltage peaks. This can be compensated by
installing an LC filter or even better a sinus filter
between the frequency converter and the motor.
For further details, please contact your frequency
converter supplier or Grundfos.
6. Motor installation
7. Fitting the pump to the motor
1. Use pipe clamps when handling the motor.
2. Place the motor in vertical position at the
borehole. See fig. 17.

7.1 Fitting of submersible drop cable and
motor cable
Before fitting the motor cable to the motor, make
sure that the cable socket is clean and dry.
To ease fitting of the cable, lubricate the rubber parts
of the cable plug with non-conducting silicone paste.
Tighten the screws holding the cable to the torques
stated:
Connect the motor cable to the drop cable by use of
original Grundfos cable termination kits, such as
shrink tube type KM or cable termination kit type M0
to M4.
If necessary, shorten the motor cable to ensure that
it is always covered with pump medium prior to
making the cable jointing as described above.
7.2 Maximum installation pressure
7.3 Lowering the pump
Grundfos recommends checking the borehole by
means of an inside calliper before lowering the pump
to ensure unobstructed passage.
Lower the pump assembly carefully into the
borehole, taking care not to damage the motor cable
and the submersible drop cable.

9. Fault finding
10. Checking the motor and cable
Fault Cause Remedy
1. The motor does
not run.
a) The fuses are blown. Replace the blown fuses. If the new ones
blow too, check the electrical installation
and the submersible drop cable.
b) The ELCB or the voltage-
operated ELCB has tripped.
Cut in the circuit breaker.
c) No power supply. Contact the power supply company.
d) The motor-protective circuit
breaker has tripped.
Reset the motor-protective circuit breaker
(automatically or possibly manually). If it
trips again, check the voltage. If the voltage
is OK, see items e) - h).
e) Motor-protective circuit breaker/
contactor is defective.
Replace the motor-protective circuit
breaker/contactor.
f) Starter device is defective. Repair or replace the starter device.
g) The control circuit has been
interrupted or is defective.
Check the electrical installation.
h) The pump/submersible drop
cable is defective.
Repair or replace the pump/cable.
1. Supply voltage
TM00 1371 5092
Measure the voltage between
the phases by means of a
voltmeter. On single-phase
motors, measure between
phase and neutral or between
two phases, depending on the
type of supply. Connect the
voltmeter to the terminals in
the motor-protective circuit
breaker.
When the motor is loaded, the voltage should be
within the range specified in section 5.1 General.
The motor may burn if there are larger variations in
voltage. Large variations in voltage indicate poor
power supply, and the motor must be stopped until
the defect has been remedied.
English (GB)
20
2. Current
consumption
TM00 1372 5092
Measure the amps of each
phase while the pump is
operating at a constant
discharge head (if possible, at
the capacity where the motor
is most heavily loaded). For
maximum operating current,
see nameplate.
On three-phase motors, the difference between the
current in the phase with the highest consumption
and the current in the phase with the lowest
consumption must not exceed 5 %. If so, or if the
current exceeds the rated current, the following
faults are possible:
The contacts of the motor-protective circuit
breaker have burnt.
– Replace the contacts or the control box for
single-phase operation.
Poor connection in leads, possibly in the cable
joint.
– See item 3.
Too high or too low mains voltage.
– See item 1.
The motor windings are short-circuited or partly
disjointed.
– See item 3.
Damaged pump is causing the motor to be
overloaded.
– Pull out the pump assembly for overhaul.
The resistance value of the motor windings
deviates too much (three-phase operation).
– Move the phases in phase order to a more
uniform load. If this does not help, see item 3.
Items 3 and 4: Measurement is not necessary when the supply voltage and the current consumption are
normal.
3. Winding
resistance
TM00 1373 5092
Disconnect the submersible
drop cable from the motor-
protective circuit breaker.
Measure the winding
resistance between the leads
of the drop cable.
Three-phase motors: The deviation between the
highest and lowest value must not exceed 10 %. If
the deviation is higher, pull out the pump assembly.
Measure motor, motor cable and drop cable
separately, and repair/replace defective parts.
Note: On single-phase, 3-wire motors, the
operating winding will assume the lowest
resistance value.
