FIELD OF APPLICATION The following instructions apply to the three-phase asynchronous electric motors manufactured by BONFIGLIOLI RIDUTTORI S.p.A., series: - BX, BE, BN - MX, ME, M in their standard version, with or without brake. Special versions as described in the catalogues and/or in offers, or special applications (for example, power supply from inverter) will require additional information.

Upon receipt of the motor, check that it was not damaged during transportation; if damage is noted, inform the carrier immediately. In addition, check that the characteristics stated on the plate conform to those ordered and confirmed by BONFIGLIOLI RIDUTTORI S.p.A. Transport and handling Cartons containing more than one motor are usually attached to wooden boards to facilitate handling by forklifts or transpallets.

Motors may be handled individually by lifting them with belts or chains (if required due to weight). Motors of frame sizes BX 100 / MX3, BE 100 / ME3, BN 100 / M3, and larger, are provided with an eyebolt / lifting point for lifting purposes. The eyebolts / lifting points are suitable for lifting the motor only.

Make sure that the motor is well-ventilated, that there is nothing to obstruct the free circulation of air, and that no situation will arise that could block the regular heat dissipation. The installation must also allow the performance of ordinary maintenance on the motor and, if sup- plied, of the brake.
WIRING Norms applicable to all motors Use cables with suitable section for the rated current and for installation conditions, avoiding exces- sive heating and/or voltage drops. Connection at the terminal board must be performed according to the diagrams shown in chart below or according to the instructions supplied in the terminal box, using the appropriate plates, nuts and washers.

Ventilation Motors are cooled through outer air blow (IC 411 according to CEI EN 60034-6) and are equipped with a plastic radial fan, which operates in both directions. Ensure that fan cover is installed at a suitable distance from the closest wall so to allow air circulation and servicing of motor and brake, if fitted.

Scheme (A) - Brake power supply from motor terminals and a.c. line disconnection. Delayed stop time t2 and function of motor time constants. Mandatory when soft-start/stops are required. Scheme (B) - Separate supply of brake coil and a.c. line disconnect. Regular stopping time, inde- pendent on time constants of motor.
Switch-pole motors, nine pin motors (motors with voltage in ratio 2) and, at request, single-pole mo- tors with separate power supply are equipped with an auxiliary terminal board with 6 terminals for brake connection. In this version, motors feature a larger terminal box. See diagram: Brake Auxiliary terminal board...
MAINTENANCE Before any intervention, the motor, auxiliary circuits and/or accessories must be disconnected from the mains. In particular: - check disconnection from the electrical mains, - provide suitable protections from exposed live parts, - duble check that accidental restarts are not possible under any circumstances. It is recommended that periodical checks of motor operating conditions are scheduled as a routine maintenance practice.

Check the air gap periodically and re-adjust it if dimension T is found exceeding the min/max values indicated in diagram. Particularly, brake may become noisier if gap is wider than the max value. In extreme cases releasing of the brake might also be affected. If the brake disengagement device is fitted, too wide a gap may lead the braking torque to drop significantly as a consequence of the reduced play in the release mechanism.

Brake torque setting on motors with a.c. brake (FA) Brake torque can be adjusted steplessly by changing the preload of springs (3). WARNING: For safety reasons, brake torque will not be set lower than 30% of rated value, even at springs fully unloaded.
Page 16
Brake torque setting on motors with a.c. brake (BA) Loosen locking nut (2). Through nut (1) adjust the air gap and restore distance “T” to its minimum value, as listed in the chart Repeat the operation symmetrically on each stud bolt holding the brake. When setting is complete tighten nuts (1) and (2) on each stud bolt.
