Page 11: Mechanical Installation
For lifting and transporting the motor use the motor eyebolts (when provided) keeping in mind that these are suitable only for lifting the motor and not other machines fitted to it; be sure that load is properly balanced and provide lifting systems, and cables of adequate section. If necessary, motor masses are stated in Rossi technical catalogs. Mechanical installation... - Page 12 V-belts should not be excessively tensioned in order to avoid excessive loads on bearings and motor shaft (for maximum loads on shaft end and relevant bearing life see Rossi catalogs). Motor is dynamically balanced; in case of standardized shaft end the balancing is obtained with half key inserted into the shaft end and exclusively for the nominal rotation speed (in order to avoid vibrations and unbalances it is necessary that also power transmissions are balanced with half key).

Page 13: Electrical Installation
Installation Electrical installation Before putting into service and after long stillstanding or storing periods it is necessary to measure insulation resistance between the windings and to earth by adequate d.c. instrument (500 V). Insulation resistance control Attention! Do not touch the terminals during and just after the measurement because of live terminals. Insulation resistance, measured at +25°C winding temperature, must not be lower than 10 MΩ... - Page 14 Installation For single-phase motors follow the instructions on Fig. 2.

Page 21: Maintenance
Maintenance Motor periodical maintenance Before carrying out maintenance, make sure that you have disconnected the power supply to the motor and other accessories (if any) and secured the motor against accidental insertion. Releasing the brake runs the risk of inhaling brake dust; wear a protective mask. Motor surfaces can reach high temperatures. - Page 22 Maintenance HBZ, HEZ brake periodical maintenance Verify, at regular intervals, that air-gap and backlash "g" (see Fig. 6) of release lever pullers, if any, are included within values stated in Tab. 5 (remove the wear dust of friction surface, if any). Excessive air-gap value deriving from friction surface wear makes brake noise level rise and could prevent its electric release.
- Page 23 Maintenance HBF brake periodical maintenance Verify, at regular intervals, that air-gap and backlash "g" (see Fig. 8) of release lever pullers, if any, are included within values stated in Tab. 6 (remove the wear dust of friction surface, if any). Tab.
- Page 24 Maintenance HBV (HBVM) brake periodical maintenance Verify, at regular intervals, that air-gap is included between values stated in Tab.7. Excessive air-gap value could produce: decrease of braking torque up to zero, rise of brake noise level, and even miss of electric release. Fig.9.
