TRANSLATION OF THE ORIGINAL INSTRUCTIONS
4.5- 4.5- ELECTRICAL CONNECTION
MACHINE STATUS: positioned in the area designated for use.
OPERATORS: 1 maintenance electrician
BEFORE MAKING THE ELECTRICAL CONNECTION, MAKE SURE THAT THE AVAILABLE
VOLTAGE AND FREQUENCY CORRESPOND TO THOSE INDICATED IN THE MACHINE NAME
PLATE (S. PAR.2.3.2).
CHECK THAT THERE IS AN EFFICIENT EARTHING SYSTEM.
EFER TO THE INDICATIONS IN THE ELECTRICAL DIAGRAM FOR THE DIMENSIONS OF THE
ELECTRICAL POWER INPUT LINE (THE ELECTRICAL DIAGRAM IS IDENTIFIED ON THE
MACHINE NAME PLATE WITH THE ABBREVIATION W.D.-S. PAR.2.3.2).
WARNING: THE MACHINE IS NOT PROTECTED AGAINST ELECTROCUTION HAZARD
CAUSED BY INDIRECT CONTACT.
PROTECTION AGAINST INDIRECT CONTACT IS THE RESPONSIBILITY OF THE CUSTOMER
WHO, FOR THIS PURPOSE, MUST MAKE USE OF SPECIALIZED PERSONNEL (ELECTRICAL
MAINTENANCE PERSONNEL- SEE PAR. 1.3).
FOR THIS PURPOSE IT IS SPECIFIED THAT FOR:
• TT PLANTS SUPPLIED THROUGH LOW VOLTAGE PUBLIC POWER DISTRIBUTION
SYSTEMS,
• TN PLANTS, SUPPLIED THROUGH MEAN VOLTAGE PUBLIC POWER DISTRIBUTION
SYSTEMS,
THE MACHINE’S FEED LINE MUST BE PROTECTED BY A GROUND FAULT CIRCUIT
INTERRUPTER:
• DEDICATED (TYPE B RECOMMENDED) AND INDEPENDENT FROM THAT OF THE
PREMISES AND OTHER USERS,
• ADJUSTABLE BOTH IN CURRENT (0.03 – 0.3 - 1A RECOMMENDED) AND TIME ( 0 – 0.3 - 1
- 3 SECONDS RECOMMENDED),
• COMPATIBLE WITH THE USER’S GROUND SYSTEM (REF. IEC 60364-4-41; HD 60364-4-
41).
FOR ENVIRONMENTS WITH A HIGH RISK OF FIRE, THE MAXIMUM DIFFERENTIAL CURRENT
VALUE MUST BE EQUAL TO 1A (VALID ALSO FOR TIME DELAYED MODELS).
IN CASE OF TN TYPE PLANTS, THE SYSTEM MUST BE TN-S TYPE WITH NEUTRAL AND
SEPARATE PROTECTIVE CABLES (IEC 60364-4-482; HD 384.4.482).
IT IS ADVISABLE TO INSTALL A PROTECTION DEVICE IN CONFORMITY WITH THE
SPECIFICATIONS IN THE ELECTRICAL DIAGRAM UPSTREAM OF THE MACHINE>
AN AUTOMATIC SWITCH OR DELAYED ACTION FUSES (S. THE TABLE GIVEN IN THE
ELECTRICAL DIAGRAM).
WITH TRACK WITH SINGLE SPEED (12 m/min - STANDARD): THE MACHINE ELECTRICAL
EQUIPMENT IS ENVISAGED TO CORRECTLY WORK WITH A POWER SUPPLY VOLTAGE
WITHIN 0,9 AND 1,1 TIMES THE NOMINAL VOLTAGE (S. ELECTRICAL DIAGRAM).
WITH TRACK WITH DOUBLE SPEED (12 OR 18 m/min - OPTIONAL): THE MACHINE
ELECTRICAL EQUIPMENT IS ENVISAGED TO CORRECTLY WORK WITH A POWER
SUPPLY VOLTAGE WITHIN 0,95 AND 1,05 TIMES THE NOMINAL VOLTAGE (S. ELECTRICAL
DIAGRAM).
THE MANUFACTURER REFUSES ALL RESPONSIBILITIES FOR FAILURES AND FAULTY
OPERATIONS CAUSED BY SUDDEN CHANGES OF VOLTAGE.
