5.2 INSTALLING THE ELECTRIC MOTOR
Further to all the precautions indicated above, when installing a standard IEC 72-1 electric motor,
the following precautions must also be observed:
• Do not force the coupling and do not use inappropriate tools during assembly. Take care not to
damage the at/cylindrical coupling surfaces.
• Do not force the rotary coupling mechanisms with heavy overhung or thrust loads.
• T
o facilitate assembly, use a lubricating synthetic oil paste such as Klüberpaste 46 MR 401 or
another product with similar properties and application range.
• Provided all the above checks have been performed and passed and all other instructions
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 2014/34/EU.
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
satised, the User shall be responsible for analysing the risks attendant on this particular
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-certication by the assembler, shall the assembly,
including the gear unit itself, be compliant with the requirements of Directive 2014/34/EU.
