6INSTALLATION

6.1 Safety warnings

MOTORS CANNOT BE CONNECTED DIRECTLY TO THE ELETRICITY GRID. A PROPER CIRCUITS AND

DEVICES FOR MOVEMENT MANAGEMENT IS REQUIRED.

WHEN THE MOTORS MUST BE POWERED BY A CONVERTER (ELECTRIC DRIVE), THIS MUST BE CHOSEN

BY QUALIFIED PERSONNEL.

IN CASE THERE ARE INVOLVED ELECTRONIC DRIVE AND CONTROL DEVICES ON THE BEVEL GEARBOX

MOVING CONTROL, REFER TO MANUALS FOR ALL THE NECESSARY INFORMATION AND CORRECT

INSTALLATION AND MAINTENANCE OF THE PRODUCT.

BEFORE TO PROCEED TO THE ELECTRIC CONNECTION, MAKE SURE THE SUPPLY VOLTAGE IS TURNED

OFF.

BEFORE TO TURN-ON THE MOTOR, MAKE SURE THE ELECTRIC CONNECTIONS ARE TIGHTENED AND

STABLE.

CHECK POWER SUPPLY CABLES NOT TO BE DAMAGED DURING THE COMMISSIONING. POWER

SUPPLY CABLES MUST BE OUT OF HEAT SOURCES AND MOVING ORGANS.

DURING FUNCTIONING ARE PRODUCED MAGNETIC, ELECTRIC AND ELECTROMAGNETIC FIELDS. THIS

MAY BE DANGEROUS FOR PEOPLE THAT USE CARDIAC STIMULATOR (PACEMAKER), IF NOT

SUFFICIENT DISTANCE.

DO NOT DISCONNECT ANY CONNECTION DURING OPERATION OR IN PRESENCE OF SUPPLY VOLTAGE.

BEFORE TO TURN-ON THE MOTOR, MAKE SURE THE MECHANICAL CONNECTIONS OF THE BEVEL

GEARBOX REMAIN TIGHTENED AND STABLE, ALSO DURING THE OPERATION.

DURING THE COMMISSIONING, UNEXPECTED MOVEMENT OF THE MOTOR MAY BE CAUSED BY:

WIRING ERRORS

MOUNTING ERRORS

DAMAGES ON POWER SUPPLY CABLES

HARDWARE OR SOFTWARE ERRORS

DRIVER PARAMETERS ERRORS

OPERATION IN CONDITIONS OUTSIDE THE SPECIFICATIONS PROVIDED BY THE

CATALOG AND THIS MANUAL

MAKE SURE THE SAFETY PROTECTION OF THE MACHINE (MECHANICAL AND ELECTRICAL) ARE

ACTIVE.

DURING OPERATION, TEMPERATURE OF THE EXTERNAL SURFACE OF MOTORS OR GEARBOXES CAN

REACH HIGH TEMPERATURES. HOT SURFACES ON GEARBOXES CAN CAUSE BURNS AND SHOULD NOT

BE TOUCHED.

6.2 Bevel gearbox installation

ALL MECHANICAL AND ELECTRICAL PROTECTION MUST BE INSTALLED AND ACTIVATED TO PREVENT

DAMAGE TO PERSONS OR PROPERTY.

Check that all plant fixing elements are well machined and cleaned, and that they fit the dimensions

of the gearbox fixing elements they have to be fixed to.

6.2.1 Identification of bevel gearbox housing sides

Side C is the side of the main input (solid shaft or IEC motor flange).

Side A and side B correspond to the main output axis of the gearbox (solid shaft, cylindrical with key, on one

or both sides, or hollow shaft with cylindrical hole and keyway).

On side D and/or side E and/or side F it is possible to mount a solid shaft with hub, cylindrical with key, as

additional output.
