In order to obtain complete satisfaction with your new
LEROY–SOMER gearless machine, it is important to
comply with the following instructions.
1. - RECEIPT
Initial checks :
- As soon as you receive the machine, inspect the
state of the packing and the machine. In the event of any
damage having been caused by transportation, notify
your haulage contractor.
- Next, ensure that the identification plate conforms
with the contract specifications and certified data.
2. - STORAGE
2.1 - Storage area
The storage area must be dry, and sheltered from the
elements. With a minimum temperature of -40
°
C, it
should not be subject to frequent temperature variations
(to avoid the risk of condensation), and should be free
from vibration, dust and corrosive gases.
2.2 - Long-term storage (> 3 months)
- Place the motor in an horizontal position in a sealed
watertight package (heat-sealed bag, for example)
containing a deshydrating sachet and bag large enough
to protect the machine, taking account of its size and the
humidity in the storage area.
- The grooves of the traction sheave are protected by a
special wax; don't remove this protective film, it protects
the exposed surfaces.
- In case of vibrations in the warehouse, it is recom-
mended to rotate the traction sheave twice a month mini-
mum (this can be done by releasing brake with manual
realesed system or by opening brake arms). After opera-
tion put the brake back into its original position. Make
sure the protective paper between the lining and the
brake wheel is still in position.
3. - ENVIRONMENT
Rated characteristics for these motors are given for a
normal environment (specified in IEC 34.1) :
- altitude 1000 m or less,
- maximum relative humidity: less than 95%,
- temperature between -16 and + 40
°
C.
More stringent specifications can be accommodated by
derating if the particular requirements are stated at the
time of ordering.
4. - COMMISSIONING
4.1 - Insulation inspection
(before installation)
If the motor has been stored for several months, it is
essential to check that :
• the inside is clean and free of condensation;
•
the motor is correctly insulated (minimum of
>100 M
Ω
powered at 500 V.D.C.) after disconnection of
all the electronic circuits.
WARNING : Do not apply the megohmmeter to
the thermal detector terminals, as this may
damage them.
If the correct insulation value is not reached, the motor
should be dried out as follows :
4.1.1 - By heating externally
- Place the motor in an oven at 70
°
C, ensuring all
openings are free of obstruction, for 24 hours or more
until the correct insulation is obtained.
- Take care to rise the temperature gradually to avoid
condensation.
- While drying, make regular checks on the insulation
values which will tend to fall initially and then rise.
4.1.2 - By heating internally
Connect the three motor winding in serial. Supply them
with a low DC voltage (to get 10% of rated current calcu-
lated with the winding resistors) increase voltage until
the current get 50% of rated current.
It must be supplied
during approximatly four hours. The temperature of the
housing shall not exeed 50
°
C.
4.2 - Installation
Incorrect lifting methods may be dangerous
for personnel and may cause serious dam-
age to the machine.
Check that the machine weight is below the lifting capac-
ity of any sling or hook. The only way to properly lift the
complete machine is to attach it by points which are rec-
ommended (see figure 1 page 3).
Motors should be installed in a location where cooling air
(which must be low in humidity, free of dust, steam and
corrosive gases) can enter and exit freely. Ensure that
warm air emissions cannot be drawn back in (motor
against a wall for example).

IMPORTANT :
Contact with any live or rotating parts
may cause injury. Never touch the motor
during operation, as this is likely to be-
come hot.
Installation, servicing and maintenance must only be
carried out by a qualified member of staff.
LEROY-SOMER cannot be held responsible for any
problems arising from failure to comply with the
instructions in this manual.
The machine is under warranty as long as it is not
partially or completely dismantled without LS
assistance (or approval) during the warranty period.
CAUTION
Make sure the car is mechanically immobilized before
performing any maintenance on the motor or on the
brake.
