(1)
Power absorbed by the compressors and fans at the limit operating conditions (i.e. with a saturated inlet temperature of 15 °C and a conden-
sation 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 005 - 007 models do not need ferrite rings.
—
The models 011 and 015 with single phase electrical sup-
py need a ferrite ring (supplied with the unit) installed on
phase and neutrak cabes (L*N), near the electrical supply
therminal block.
—
The 011T e 015T three phases models needs two ferrite rings
(suppy with the unit), one installed near the electrical
supply therminal block around the phases and neutral ca-
bles, 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 val-
ue +/- 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 disconnec-
tion in accordance with the conditions foreseen for over-
voltage 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 ade-
quate breaking capacity and differential protection, in-
stalled near the appliance
—
connect the device to a properly functioning earthing sys-
tem
—
make sure that the electrical power supply system is com-
pliant with the current national safety standards
—
make sure that the power supply line impedance is con-
sistent with the unit's power consumption, as indicated on
the unit's data plate
—
for any electrical intervention, always refer to the wiring
diagrams contained within this booklet
0
Do not use gas and water pipes to ground the unit.
0
It is forbidden to pass the power supply and room thermo-
stat cables near hot surfaces (delivery pipes). If contact with
parts above 50 ° C is possible, use a suitable type of cable.
