Installing The Electric Motor - BONFIGLIOLI 300 Series Installation Use And Service Manual

Installing accessories on splined shafts
Do not use hammers or other tools that might damage the gear unit's shafts or bearings when
mounting external parts. Instead, proceed as illustrated in the diagram below:
Always use the stop end plate supplied with the gear unit.

5.2 - INSTALLING THE ELECTRIC MOTOR

Further to all the precautions indicated above, when installing a standard IEC 72-1 electric motor, the follo-
wing precautions must also be observed:
•
Do not force the coupling and do not use inappropriate tools during assembly. Take care not to damage
the flat/cylindrical coupling surfaces.
•
Do not force the rotary coupling mechanisms with heavy overhung or thrust loads.
•
To facilitate assembly, use a lubricating synthetic oil paste such as Klüberpaste 46 MR 401 or another pro-
duct with similar properties and application range.
•
Provided all the above checks have been performed and passed and all other instruc-
tions in this manual have been strictly observed, an electric motor with ATEX rating
equal to or greater than that of the gear unit may be installed, thus forming a gearmotor
which itself complies with the provisions of Directive 94/9/EC.
If, instead, the assembly of the motor to the gear unit requires actions other than those
prescribed in this Manual or one or more of the manual's prescriptions have not been
satisfied, the User shall be responsible for analysing the risks attendant on this particu-
lar motor/gear unit combination. The risk analysis is in any case obligatory if the motor
is powered by an inverter.
Only in this way, and subject to self-certification by the assembler, shall the assembly,
including the gear unit itself, be compliant with the requirements of Directive 94/9/EC.
