ELECTRICAL CONNECTION
The electric power supply line must be made using cables with a suitable section (*) for the machine power and it must
include
3 phase 1 earth cable
.
•
For models in which there is a dryer or a heating element, 1 neutral cable is also necessary.
•
Compressors using a 220V power supply do not require a neutral cable.
•
It is indispensable to install between the power supply line and the compressor control panel:
- either an automatic magnetothermal switch with appropriate circuit breaking capacity and operating
sensitivity curve “D”;
- or a disconnecting switch with suitable capacity equipped with delayed fuses, AM curve, for motor starting.
(To choose between a magnetothermal switch or a disconnecting switch with fuses, follow the instructions of the
regulations in force in the country of installation.)
•
The switch must be within easy reach of the operator.
(*)
For the section of the cables, follow the indications given in the “electric data table” in the manual.
The cables must be of an approved type, with a suitable degree of insulation.
THE ELECTRIC POWER MAINS TO WHICH THE COMPRESSOR IS CONNECTED MUST
SATISFY THE TECHNICAL CHARACTERISTICS GIVEN IN THE PREVIOUS TABLES AND COMPLY
WITH THE REQUIREMENTS CONTEMPLATED BY THE REGULATIONS IN FORCE IN THE
COUNTRY OF USE.
THE ELECTRICAL CONNECTION OF THE COMPRESSOR TO THE ELECTRIC POWER LINE
MUST BE CARRIED OUT BY A QUALIFIED ELECTRICIAN, IN POSSESSION OF THE TECHNICAL
AND PROFESSIONAL SKILLS REQUIRED BY THE REGULATIONS IN FORCE.
UPSTREAM FROM THE ELECTRIC POWER LINE IT IS OBLIGATORY TO INSTALL A SUITABLE
ISOLATING DEVICE WITH DIFFERENTIAL PROTECTION, COORDINATED WITH THE
EARTH SYSTEM.
THE MANUFACTURER DECLINES ALL RESPONSIBILITY FOR COMPRESSOR BREAKDOWNS OR
MALFUNCTIONS CAUSED BY SUDDEN CHANGES IN THE ELECTRIC VOLTAGE BEYOND THE
TOLERANCES CONTEMPLATED BY THE POWER DISTRIBUTION BOARD (VOLTAGE ±10%).
FAILURE TO RESPECT THE ABOVE WARNINGS MAY CAUSE IRREPARABLE DAMAGE TO THE
ELECTRICAL EQUIPMENT OF THE COMPRESSOR AND THE CONSEQUENT VOIDING
OF THE GUARANTEE.
THE MANUFACTURER DECLINES ALL RESPONSIBILITY FOR ANY DAMAGE CAUSED TO
PERSONS, ANIMALS AND/OR THINGS DUE TO THE INCORRECT ELECTRICAL CONNECTION OF
THE COMPRESSOR.
