INSTALLATION & MAINTENACE MANUALRCOe2100/03.06284 - InstallationThis section is intended for personnel (MECHANICAL MAINTENANCE TECHNICIAN) assigned to install themotor on the machine or system for which the unit has been purchased. Therefore the importance of thissection is emphasised since the optimum operation of the group machine/system – motor is theconsequence of the correct assembly of the parts; the correct installation will limit the sources of danger forpeople working near to the structure.4.1 – Applying the Motor to the SystemManufacture the assembly flange on the machine/system where the motor has to be installed: the relevantsurface has to be perfectly smooth, completely de-greased and non-deforming.The motor must be assembled by using bolts whose size must be selected based on fixing holes dimensions:appropriate lock washers must be used. The tightening torque must be proportional to the momentumgenerated by the motor: if necessary, the 70% of the bolt yield load can be reached (pls. refer to the tablehere below). Use fixing bolts belonging to resistance class 8.8 or higher.MAXIMUM TIGHTENING TORQUE FOR MOTOR FIXING BOLTSMAX.
