11 ELECTRICAL CONNECTIONS
WARNING!
It is necessary to always refer to the electrical diagram supplied with the unit.
The electrical wiring diagram suggests dimension values for the electricity line and the cor-
responding protective devices.
WARNING!
For signal cables:
Avoid splicing
Connect one end only ofshield-
ing to earth
Do not install with power cables
The electrical connections of the air conditioner must satisfy the following prescriptions:
• The sizing of the power supply line, to be carried out by the installer, must comply with the indications provided in the technical documen-
tation and the regulations of the country where the installation is carried out.The Manufacturer is not liable for any damage resulting from
incorrect sizing.
• The electronic devices inside the unit are not compatible with IT distribution systems (Neutral insulated from the earth) as they could be
damaged.
• To avoid potential damage to electrical and electronic equipment caused by voltage surges in the electricity supply line, the Manufacturer
recommends evaluating the necessity of installing SPDs (Surge Protection Devices) appropriately rated for the type of installation and the
frequency of direct lightning strikes on the electricity supply line (EN 62305/1-4).
• To prevent operating problems with the system, it is necessary that no other loads, even those that are part of the same system, are con-
nected downstream of the main switch for the air conditioner, unless explicit permission is granted by the Manufacturer.
• The electronic devices inside the unit require that the dierential protection is calibrated from 30 to 300 mA, in order to prevent untimely
interventions.
• The electrical power supply line must have the following characteristics in compliance with EN 60654-2 & EN 61000-4-11 standards, in order
to prevent possible malfunction of the installed components:

Dierence of voltage between the phases 0 Vac ± 2% - 7.6 Vac + 7.6 Vac
Frequency 60 Hz ± 2% 58.8 Hz 61.2 Hz
Variations, short interruptions and voltage dips
In the presence of variations, interruptions and voltage dips of short duration and / or intensity, the unit maintains its normal performance. If they
are longer and / or of greater intensity, it is possible that the unit will shut down, or the components belonging to the unit.
Upon restoration of the correct values of the supply voltage, the equipment restarts automatically, without losing the stored data and consistently
with the status of the components that are part of the unit.
