2.7. ELECTRICAL CONNECTIONS
DANGER!
Install a general automatic switch with characteristic delayed curve, of adequate capacity and interruption power, in a protected area
near the unit (the device must be able to interrupt the presumed short circuit current, whose value should be determined on the basis
of the system characteristics). Earth connection is compulsory by law to ensure user safety while the machine is in use.
DANGER!
The electrical connection of the unit must be carried out by qualified personnel, in compliance with the regulations applicable in the
country where the unit is installed. Non-conforming electrical connections releases from liability concerning damage to objects and
persons. In making the electrical connections to the board, cables must be routed so that they do not touch the hot parts of the ma-
chine (compressor, flow pipe and liquid line). Protect the wires from any burrs.
DANGER!
Check the tightness of the screws that secure the conductors to the electrical components on the board (vibrations during handling
and transport could have caused them to come loose).
IMPORTANT!
For the electrical connections of the unit and accessories, refer to the relative wiring diagram.
Check the value of the mains voltage and frequency that must fall within the 400 V ± 10% (360-440V) limit for the voltage and 50 Hz ± 1% for the frequency.
Check the phase unbalance: it must be less than 2%.
Example:
L1-L2 = 388V, L2-L3 = 379V, L3-L1 = 377V
Average of values measured = (388+379+377) / 3 = 381V
Maximum deviation from the average = 388-381 = 7V
Unbalance = (7 / 381) x 100 = 1,83 % (acceptable as it is within the envisaged limit).
IMPORTANT!
Operation outside the limits could affect correct machine operation.
The safety door interlock automatically prevents electric power being fed to the unit if the cover panel over the electrical panel is opened. After opening the
front panel of the unit, feed the power supply cables through the cable clamps in the external panelling and then through the ducts at the base of the electric
board. The electrical power supplied by the single-phase or three-phase line, must be taken to the main isolator switch. The power supply cable must be
flexible with a polychloroprene sheath not lighter than H05RN-F: for the section, refer to the following table or wiring diagram.

The earth conductor must be longer than the other conductors in order to ensure that if the cable fastening device should become slack, it will be the last to
be stretched.
