9 - elecTrIcal connecTIonS (fig. 15/16)

All field electrical connections are the responsibility of
the installer.
WARNING: Make water connections before electrical
connections.Make ground connection prior to any other
electrical connections.
CAUTION:
• Connect the power cable correctly. If the power cable
is connected in a wrong way, electric parts may be
damaged.
• Connection to the mains supply is of the Y type;
therefore, the cable must only be replaced by the
technical support in order to prevent any risk.
• Use the specified cables for wiring and connect them
firmly to the terminals.
WARNING:
• Be sure to provide grounding; inappropriate
grounding may cause electric shock.
• Do not connect ground wires to gas pipes, water
pipes, lightning rods or ground wires for telephone
cables.
DANGER: Do not modify this unit by removing any of
the safety guards or by by-passing any of the safety
interlock switches.

FINAL CHECK

WARNING:
• If refrigerant gas leaks out during the installation
work, ventilate the room immediately.
• If refrigerant gas leaks into the room and flows near
a fire source, such as a cooking range, poisonous gas
is generated.
Contact the qualified service if one of the following events
takes place:
• hot or damaged power supply cable;
• unusual noise during operation;
• frequent operation of the protection devices;
• unusual smell (such as smell of burning).
DANGER: Electrical shock can cause severe personal
injury or death. These operations are carried out by
qualified personnel only.
WARNING:
• This unit complies with Machinery (2006/42/EC),
electromagnetic compatibility (2004/108/EC) and
pressure equipment (EEC/97/23) Directives.
• To avoid electric shock or fire make sure these
operations are carried out by qualified personnel
only.
• Ensure that national safety code requirements have
been followed for the main supply circuit.
• Follow all current national safety code requirements.
• Ensure that a properly sized and connected ground
wire is in place.
• Check that voltage and frequency of the mains power
supply are those required; the available power must
be adequate to operate any other possible appliances
connected to the same line.
• Check that the impedance of the mains power supply
is in conformance with the unit power input
indicated in the rating plate of the unit.
• Make sure that properly sized disconnecting and
safety switches are installed.
• For installation of wired remote controller please
refer to the control installation manual.
• All devices for disconnection from the power supply
mains must have a contact opening (4 mm) to allow
total disconnection according to the conditions
provided for the overvoltage class III.
• The imbalance between voltage phases must always
be less than 2%.

9.1 - electrical connections (fig. 16)

Remove the front panel, the electric parts appear at the
front side.
The power supply cables can be inserted into the
pipeholes. Be sure to fix the power cable with bundling
band sold on the market so that they do not make contact
with the compressor and the hot pipes.
To ensure good tensile strength, the electric cables must
befastened using the cable-holder on the plate
(See fig. 16 A).
If the unit operates at a voltage outside the limits or with a
phase imbalance above 2%, this constitutes improper use
and may afect the warranty. If the phase imbalance is hig.
her than 2%, contact the local electricity board
immediately.
