II.8 Electrical connections
DANGER!
Always install a general circuit breaker in a protected area close to the
machine (this switch must have a delayed characteristic curve, suitable
flow rate and interruption power and be equipped with protection
devices against short-circuits and earth leakage in order to disconnect
the system from other utilities) and with 3 mm minimum contact
opening distance.. 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 coun-
try where the unit is installed. Non-conforming electrical connections
releases HITECSAfrom 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 machine (com-
pressor, 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).
DANGER!
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 three-phase line, must be taken to
the main isolator switch. The power cable must be flexible for outdoor use:
for the section, refer to the following table or to the wiring diagram.

(*) The indicated supply sections (cable type FG16) are approximate. The
installer is responsible to suitably size the electrical supply line switch - in-
cluding the earth cable - according to: line length, distribution system, type
of cable, type of layout, maximum absorption of the unit
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.
II.8.1 Remote management through connections prepared
by the installer
The connections between board and remote controls must be made with
shielded cable (make sure the shield is continuous throughout the length
of the cable) consisting of 2 twisted 0.5 mm² wires and the shield. The
shield must be connected to the earth screw on the panel (on one side
only). The maximum distance allowed is 30 m.
Lay the cables far from the power cables or cables with a different voltage
and cables that emit electromagnetic disturbance. Do not lay the cables
close to equipment that could create electromagnetic interference.
