To ensure that the LEROY-SOMER motor you have just
purchased is entirely satisfactory, it is essential to adhere to
the following instructions.
IMPORTANT: Contact with energised or rotating
parts may cause injury. Do not touch the housing
of a motor that is in operation, as it can reach high
temperatures.
Installation, servicing and maintenance must only be
carried out by qualified personnel.
Failure to follow the instructions in this document, or to
apply them correctly, releases the manufacturer from
liability.
The product is covered by the warranty during the
guarantee period as long as any partial or total
dismantling has only been performed with the assistance
of LEROY-SOMER (or its approval).
The magnetic field on the rotor may affect pacemakers.
The motor rotor contains a powerful magnetic field. This
field may affect digital devices such as watches, mobile
phones etc.
Assembly or maintenance of the rotor must not be
carried out by people with pacemakers or any other
implanted medical electronic device.
1 - RECEIPT
Checks:
- As soon as you receive the machine, check that the nameplate on the machine conforms to your order.
- Inspect the machine as soon as it is received. If there is any damage that has been caused by transportation, contact the carrier
in the usual way.

2 - STORAGE
2.1 - Storage location
This location must be dry and protected from harsh weather
conditions, cold (temperature between -15°C and +80°C),
frequent temperature variations (to prevent the risk of
condensation), and free from vibration, dust and corrosive
gases.
If there is any vibration in the storage area, it is advisable to
rotate the driving pulley at least twice a month (the brakes are
released by the manual release system).
In certain transport conditions the grooves of the driving
pulley are protected by a special varnish. This varnish must
not be removed during storage.
2.2 - Prolonged storage (> 3 months)
Place the machine in a sealed waterproof enclosure with a
dehydrating sachet inside corresponding to the volume to be
protected and the degree of humidity of the location.
3 - ENVIRONMENT
The rated characteristics are given for operation in a standard
environment (see IEC 600034-5):
- altitude less than 1000 m,
- maximum humidity: 95%,
- temperature between 0 and 40°C.
Note:
We may be able to offer a dispensation concerning the
maximum temperature. This dispensation will need to be
confirmed on a case-by-case basis with LEROY-SOMER.
Derating may be provided if special conditions are indicated
at the time the equipment is ordered.

4 - COMMISSIONING
BEFORE INSTALLATION
If the equipment has been stored for several months, it is
essential to check the following:
- the cleanliness of the interior and that there is no
condensation
- correct insulation between the phases and the earth terminal
on the motor (minimum 100 M
Ω
at 500 V D.C. for 60 seconds)
after having disconnected all the electronic circuits if
necessary.
WARNING:
do not apply the megohmmeter to the terminals
of the thermal sensors as this may damage them.
If the required value is not reached, dry the motor using
internal or external heating.
Drying using external heating
- Place the motor in an oven at 70°C for at least 24 hours until
the correct insulation is achieved. (100 M
Ω
)
- Take care to increase the temperature gradually to clear the
condensation.
- After drying, during the cooling phase, check the insulation
value regularly, as it will initially tend to fall then rise.
Drying using internal heating
- Connect motor windings V and W in parallel in relation to U
(see drawing below).
- Read off the resistance between U and V//W.
- Apply a
low voltage
D.C. current to them (to obtain 10% of
the rated current calculated using the winding resistances),
increase the voltage until 50% of the rated current is reached.
- Maintain the power for 4 hours. The temperature of the
motor should increase slightly.
The rotors will move slightly on power-up (angular
setting of the rotor in relation to the stator).
4.1 - Installation
The installation must comply with the characteristics of the
motor indicated on the nameplate (see section 1).
It must include electrical safety devices.
Check that the handling equipment (slings, etc.) are suitable
for the weight of the machine.
Use the attachment points provided on the machine.
Check that the cables are correctly positioned so that they are
not damaged.
The motors must be installed in such a way that the cooling
air (not too damp, dust-free, and containing no vapour or
corrosive gas) circulates freely.

4.1.2 - Mechanical installation
The HPM machine must be installed on a chassis or angle bracket that is not subject to vibration and must be secured using the
fixings recommended in technical note T42.6.M018.

It is the responsibility of the user to connect the
motor in accordance with the current legislation
and regulations in the country of use. This is particularly
important as regards the size of the cables, the type and
size of fuses, the earth or ground connection, powering
down, acknowledging faults, insulation and protection
against overcurrents.
- Connect the power cables to terminals U1, V1 and W1,
in accordance with IEC 600034-1 (see section 4.2 - fig. 1).
- Connect the thermal probe to the drive.
- Connect the motor ground to earth (see section 4.2 - fig. 1).
- Connect the brakes and the microswitches.
- Connect the encoder.
4.3 - Start-up
Check that the electric controls are correctly earthed before
carrying out the first operation.
Start up the machine and check the following points:
- All the fixings and electrical connections must be correctly
tightened.
After starting up, check:
- noise
- vibration
- operation of the buttons/switches
- also check the current and voltage on the machine while it
is operating with the rated load.
- Sensor wiring (refer to the data sheet).
5 - MAINTENANCE/SERVICING
5.1 - After one month’s operation
- Check that the screws and electrical connections are
correctly tightened.
- Check the vibration. Check that there is no abnormal noise.
5.2 - Every year
- Check that the screws and electrical connections are
correctly tightened.
- Check the vibration. Check that there is no abnormal noise.
5.3 - Servicing the IP55 filter
- Only clean the filter when the PTO sensor trips (sensor
connected in accordance with paragraph 4.2).
The drive causes the sensor to trip.
Cleaning the filter
- Remove the motor rear cover.
- Remove the filter from its support.
- Blow compressed air onto the filter to remove the dust.
- Wash the filter in soapy water.
- Dry the filter to prevent water getting into the motor.
- Replace the filter in its support.
- Replace the rear cover.
