1. USEFUL INFORMATION AND SAFETY REGULATIONS
This manual contains important safety instructions which must be carefully followed during the installation
and commissioning of the device. It is advisable to pay particular attention to the paragraphs marked with
the symbol , this will reduce the risk of electric shock and prevent damage to the device.
All the operations described below must be carried out exclusively by qualied sta in compliance with
national and local safety regulations.
For all stages of installation, the instructions and warnings shown in the various chapters must be followed
step by step so as to avoid danger situations or the possibility of damaging the equipment. Every operation
that does not comply with these instructions will lead to the immediate loss of the warranty.
There can be live parts, uninsulated parts and hot surfaces while the inverter is working. Unauthorized
removal of the required protections, improper use, faulty installation or inappropriate operation and
tampering with the unit (e.g. adding extra holes) give rise to the risk of serious damage to persons and things
and lead to the immediate loss of the warranty.
The system must be connected to the mains distribution system only after the Body appointed to distribute
electricity has given its approval, as required by the national regulations in force.
Check the national regulations and local standards so that the electric installation diagram complies with
them.
Always respect the nominal voltage and current data when planning the system (see the technical data table
in Appendix E).

3. SELECTION OF INSTALLATION LOCATION
The installation location of the AURORA inverter must be chosen taking in account the followings:
•
Choose a location sheltered from direct sunlight or other sources of heat.
•
Choose a well ventilated place so as to allow good circulation of air around the unit; avoid places where
air cannot circulate freely around the unit.
•
Choose a place with sucient space around the unit to permit easy installation and removal of the
object from the mounting surfaces.
•
If more than one unit is installed, avoid placing one unit above the other so as to prevent overheating
of the unit installed above through the heat given o by the one below. Some examples of multi-
inverter installations are shown in the picture below.

ARRANGEMENTS OF UNITS MINIMUM CLEARANCES AROUND THE UNIT
4. WALL MOUNTING
The AURORA inverter should be mounted vertically, with a maximum inclination from the vertical of 5°. Any
largerinclination fromthe vertical could reducethepowerconversion capabilitywith a consequentreduction
in energy harvesting.
To correctly wall mount the inverter, follow the following procedure:
•
Drill Ø 10 mm holes to a depth of 75 mm in line with the support bracket’s xing holes (det. [A]).
•
Secure the inverter’s support bracket using the SX10 dowels and 6.3x70 screws provided. The inverter’s spring
hook (det. [B]) must be positioned at the top; the xing PEM M6 (det. [C]) must be positioned at the bottom.
•
Hook the inverter to the bracket spring (det. [B]) by the screw holes in the bracket on the back of the
inverter (det. [D]). Secure the lower part of the inverter to the PEM M6 on the bracket (det. [C]) using
the M6x10 screw, the D.18 washer and the slot in the inverter’s lower ange (det. [E]).
Note:In the PVI-8.0/10.0/12.5-TL-OUTD models the support bracket only permits the upper part of the inverter to be secured
through the procedure previously described; to secure the lower part of the inverter, in the absence of the PEM M6, you must
make additional holes in line with the slot in the inverter’s lower ange (det. [E]), and then use the SX10 dowels and 6.3x70
screws to secure the part to the wall.

5. ELECTRICAL CONNECTIONS AC, DC SIDE AND PE CONNECTION
Warning! The inverters to which this document relates to are WITHOUT ISOLATION TRANSFORMER
(transformer-less). This type involves the use of insulated photovoltaic panels (IEC61730 Class A Rating) and
theneed to maintain thephotovoltaic generatoroating withrespecttoearth: nopole of thegenerator must
be connected to earth.
Warning! Aurora inverters should be earthed (PE) via the terminal with the protective earth label ,
using a cable with an appropriate cross-section of the conductor for the maximum ground fault current that
the generating system might experience. Any damage caused to an inverter which is not earthed via the
appropriate terminal is not covered by the warranty.
Warning! Unauthorized removal of necessary protections, improper installation or tampering with the unit
(for example, the creation of additional holes, changes not covered in the guide below), cause the risk of
serious personal injury and / or property and entails the immediate loss of warranty.
Warning! Aurora inverters cannot be powered by unlimited sources of current, e.g. batteries. Powering the
device with this type of energy source can cause irreparable damage to the unit, with consequent invalidity
of the warranty conditions.
Warning! Aurora inverters are supplied with an internal protection system able to detect any ground fault occurring
on the DC side of the equipment or inside the inverter. This protection system, designed to disconnect the inverter in
the event of an accidental indirect contact or a breach of the insulation, is not capable of protecting the inverter from
a dead short of one of the poles of the solar array when the equipment is connected to the AC grid (such an event could
damage the inverter and such damage is not covered by the warranty); further, this protection system is not capable of
protecting the AC line to which the inverter is connected, for which you are recommended to install an automatic circuit
breaker which will cut out in the event of a leakage on that line. The following table shows the characteristics of such a
device that would be required for the various inverter models. The ratings (nominal current) for the switches reported
in the table below are given as approximate values: the selection of the device to be used must be based on installation
choices, such as any possible deratings due to the operative temperature of the switch.
