INSTALLATION & MAINTENACE MANUAL
RCOe2100/03.06

4 - Installation
This section is intended for personnel (MECHANICAL MAINTENANCE TECHNICIAN) assigned to install the
motor on the machine or system for which the unit has been purchased. Therefore the importance of this
section is emphasised since the optimum operation of the group machine/system motor is the
consequence of the correct assembly of the parts; the correct installation will limit the sources of danger for
people working near to the structure.
4.1 Applying the Motor to the System
Manufacture the assembly flange on the machine/system where the motor has to be installed: the relevant
surface 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 momentum
generated by the motor: if necessary, the 70% of the bolt yield load can be reached (pls. refer to the table
here below). Use fixing bolts belonging to resistance class 8.8 or higher.
