The indicated test prescriptions must be observed.
– During the loadless tests, restrain the motor shaft
tab, to prevent it from being expelled by centrifu-
gal force, and causing serious damage. To this
end, you may leave on the protection cap with
which the motor is supplied.
– Check if the bearings are moving smoothly.
– During operation, the motor-appliance combina-
tion must not be subjected to excessive vibra-
tions (as mentioned in item "Installation"). An
adequate check is necessary to this end. If nec-
essary, stop the motor and check the balance of
OPERATION
For the operating conditions, see item "Intended
use".
The motor is started by supplying voltage at nomi-
nal value to the phase terminals. The motor is
stopped by cutting power to all the phase circuits
connected to the terminals.
The overloading conditions possible on the motor
conform to standard EN60034-1 according to type
of duty (this information can be obtained from the
data-plate and catalogue).
For radial and axial loads, consult the catalogue.
The surface of the motor's external housing can
reach high temperatures. They are high enough to

MAINTENANCE METHODS
FR
Before attempting any maintenance jobs on the
electric motor or on parts of the motor-appliance
ES
combination nearby, make sure you obtain positive
answers to the following checks:
– The electrical feed circuit must be clearly and vis-
ibly switched OFF and under the control of the
maintenance person.
English
the coupled assemblies, the stability and rigidity
of the base or structure on which the motor is se-
cured, and/or the fastening elements.
– Motors equipped with a brake are adjusted and
inspected without any load applied and, there-
fore, the air gap must be re-checked during com-
missioning, in order to compensate for any
settling due to the coupling of motor to machine.
For the procedure for this operation, consult the
catalogue and/or the lay-out annexed to the mo-
tor.
ing to standard EN563. The temperature of the
housing of the ventilated models does not usually
exceed 75°C (85°C in versions without a fan).
Run a periodic check to see if there are any depos-
its and if dust has settled on the carcass or motor
housing, to avoid a worsening of thermal exchange
and overheating.
Remember that the capacitor supplied
with the single-phase models entails un-
foreseeable explosion risks, however
minimal they may be. Although the con-
sequences, in addition to the destruction
of the component, are very slight, the
user of the motor must bear this possibil-
ity in mind when analysing the risk re-
ferred, for example, to the location and
lay-out of the motor.
– All mechanical masses kinematically connected
to the motor shaft must be idle, and no possibility
of unexpected starting due to the shaft being ro-
tated by external mechanical parts.
– If the motor is excessively noisy while operating,
check if the bearings are worn and replace them
if necessary.
