The characteristics of the electrical lines must be
determined by specialized personnel able to design
electrical installations; moreover, the lines must be
in conformity with regulations in force.
The protection devices of the unit power line must
be able to stop the presumed short circuit current,
whose value must be determined in function of
system features
The power cables and the protection cable section
must be defined in accordance with the
characteristics of the protections adopted.
All electrical operations should be performed by
trained personnel having the necessary requirements
by the regulations in force and being informed
about the risks relevant to these activities.
Operate in compliance with safety regulations in
force.
Electrical data
The serial number label reports the unit specific
electrical data, included any electrical accessories.
The electrical data indicated in the technical
bulletin and in the manual refer to the standard
unit, accessories excluded.
The matriculation plate shows the indications
foreseen by the standards, in particular:
• Voltage
• F.L.A.: full load ampere, absorbed current at
maximum admitted conditions
• F.L.I.: full load input, full load power input at
max. admissible condition
• Electrical wiringdiagram Nr.
Connections
Refer to the unit electrical diagram (the number of
the diagram is shown on the serial number label).
Verify that the network has characteristics
conforming to the data shown on the serial number
label .
Before starting work, verify that the sectioning
device at the start of the unit power line is open,
blocked and equipped with sign warning.
First create the earthing connection.
Shelter the cables using adequate measure
fairleads.
Prior to powering the unit ensure that all the
protections that were removed during the electrical
connection work have been restored.
Attention
It is mandatory to use appropriately sized wire end
sleeves for connection of the power supply to the
terminal block (XC1).
Type of cable to be used for all sizes
Min.section 2.5 mm

Max.section 6 mm

Signal lines/data-lay
Do not overpass the maximum power allowed,
which varies, according to the type of signal.
Lay the cables far from power cables or cables
having a different tension and that are able to emit
electromagnetic disturbances.
Do not lay the cable near devices which can
generate electromagnetic interferences.
Do not lay the cables parallel to other cables;
cable crossings are possible, only if laid at 90°.
Connect the screen to the ground, only if there
aren’t disturbances .
Guarantee the continuity of the screen for the
entire extension of the cable.
Respect impendency, capacity and aenuaon
indicaons.
Power supply input
Fix the cables: if vacated may be subject to
tearing.
The cable don't have to touch the compressor and
the refrigerant piping ( they reach high
temparatures ).
Electrical panel protection
Do not remove the protection.
