Transportation, conservation, use and maintenance
Motive dispatches the motors in packagings suitable for any kind of transportation.
Before any maintenance intervention make sure that the power supply of the motor is off
disabling it;
Use only original spare parts following the indications provided in the catalogue for the motors;
The motor must be conserved in covered and dry ambient, without the presence of vibrations
or dust, a temperature higher then -15°C.
The exposed parts, like flanges and the shaft drive extremity, must be protected by lubricant.
It is opportune to rotate periodically the shaft in order to ensure a long-standing complete
lubrication of the bearings.
The motor must be installed and used by qualified people that know the safety requirements.
Also the installation must happen in dry climate and protected by atmospheric agents. The
working temperature and humidity must be within the limits described in the previous
paragraph “working conditions”. Motor dismantling and assembling must be done by qualified
people. Any intervention on the connection box must be done only after having disconnected
the power supply.
Eventual inspections must be done with proper tools, avoiding means that could damage the
motor. It is opportune to make periodical inspections, to guarantee the best working conditions
and making: motor cleaning, fan cooling verification, eventual abnormal noise and vibration
identification. In this last case, check the bearings (see tab.1) and, if necessary, substitute
them, as well as the rubber seal rings.
Finally, verify the correct fixture of the motor on the flange or on the feet.
Recommended precautions for ATEX motors
All maintenance and control operations on ATEX motors must be done respecting the norm
EN 60079-17. Pay attention that all screws are closed tightly.
The replacement of parts subject to wear, (like bearings and oil seals, must be done using
only original spare parts in order to preserve the safety requirements and protection degree.
The joints surfaces (for instance between housing and shields, shaft) must not be neither
machined nor painted. Such surfaces must be kept clean and, against corrosion and water
entryu, you must keep on the same a layer of silicon grease.
Repair of ATEX motors must be done respecting the norm IEC 79-19, and they can be done
only by the manufacturer or by trained and authorized external workshops.
