Power absorbed by the compressors and fans at the limit operating conditions (i.e. with a saturated inlet temperature of 15 °C and a condensation
temperature equivalent to 68.3 °C) with a rated supply voltage of 400 V

Maximum unit operating current
— apply the ferrite ring on the power supply cable to ensure
compliance with EMC standards
Ferrite rings installation:
— The 5 - 7 models do not need ferrite rings.
— The models 11 and 15 with single phase electrical suppy
need a ferrite ring (supplied with the unit) installed on phase
and neutrak cabes (L*N), near the electrical supply therminal
block.
— The 11T e 15T three phases models needs two ferrite rings
(suppy with the unit), one installed near the electrical sup-
ply therminal block around the phases and neutral cables,
the other on the same calbles but just inside the unit frame,
where the cables enter in the unit frame.
— Once the electrical connections are complete, reassemble all
the components operating in reverse order.
Check that:
— the characteristics of the electrical network are adequate for
the absorption of the appliance, also considering any other
machinery in parallel operation
— the power supply voltage corresponds to the nominal value
+/- 10%, with a maximum phase imbalance of 3%
— all disconnection devices from the power supply must have
a contact opening (4 mm) to allow total disconnection in ac-
cordance with the conditions foreseen for overvoltage class
III
Mandatory items:
— the use of an omnipolar magneto-thermal switch, padlockable
line disconnector, compliant with CEI-EN Standards (contact
opening of at least 4 mm), with adequate breaking capacity
and differential protection, installed near the appliance
— connect the device to a properly functioning earthing system
— make sure that the electrical power supply system is compli-
ant with the current national safety standards
— make sure that the power supply line impedance is consistent
with the unit's power consumption, as indicated on the unit's
data plate
— for any electrical intervention, always refer to the wiring dia-
grams contained within this booklet
0
Do not use gas and water pipes to ground the unit.

It is forbidden to pass the power supply and room thermostat
cables near hot surfaces (delivery pipes). If contact with parts
above 50 ° C is possible, use a suitable type of cable.
