6 INSTALLATION
The operations described in the paragraphs of this chapter provide both electrical and mechanical
connections of the actuator, as well as the execution of test motions at reduced speed and motor torque or
with small displacement steps.
6.1 Safety warnings
MOTORS CANNOT BE CONNECTED DIRECTLY TO THE ELETRICITY GRID. A PROPER CIRCUITS AND
DEVICES FOR MOVEMENT MANAGEMENT ON BOTH DIRECTIONS IS REQUIRED. STROKE END LIMIT
SWITCHES (MICROSWITCHES OR SENSORS) MUST BE CONTROLLED TO BE SURE THE LINEAR
MOVEMENT OF THE ACTUATOR (DUE TO THE OPERATION OF THE MOTOR OR TO THE INERTIA OF
THE MOVING PARTS) STOPS BEFORE TO REACH THE MECHANICAL STROKE END LIMITS. IN CASE THIS
HAPPENS, THE ACTUATOR CAN BE LOCKED AND THE INTERNAL COMPONENTS CAN BE DAMAGED.
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 ACTUATOR
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 ACTUATOR
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 CAN REACH HIGH
TEMPERATURES. HOT SURFACES ON ACTUATOR CAN CAUSE BURNS AND SHOULD NOT BE TOUCHED.
