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.

5.1. Selection of the AC grid connection cable
The AC grid connection cable must be selected based on the criteria below.
•
Cable type:
The choice of the type of cable for the connection to the AC grid depends on the type of inverter to be installed
(single-phase or three-phase) and on the protective earth (PE) wiring; this may be integrated in a single sheath
with the conduction line (phase or phases + neutral) or it can be on a separate wiring.
For the three-phase models the wiring choice also depends on the selected conguration type for the AC
grid connection (delta or star): in case of delta congurations (pure three-phase) the neutral conductor is not
required.
Inverter type / conguration Cable type
Single-phase inverter Three-way cable (L+N+PE) or
Two-way cable (L+N) and PE cable
Three-phase inverter with delta
grid connection
Four-way cable (R+S+T+PE) or
Three-way cable (R+S+T) and PE cable
Three-phase inverter with star
grid connection
Five-way cable (R+S+T+N+PE) or
Four-way cable (R+S+T+N) and PE cable
•
Cross-section of the internal conductor:
The cross-section of the AC line conductor must be sized in order to prevent unwanted disconnections of
the inverter from the grid due to high impedance of the line that connects the inverter to the power supply
point; in fact, if the impedance is too high, it causes an increase in the AC voltage (seen by the inverter) that,
on reaching the limit set by the regulations of the country of installation, causes the inverter to switch o.
The following table reports the minimum and maximum cross-sections of the internal conductor of each
individual AC cable for each inverter model.

•
External diameter:
To ensure environmental protection for the inverter, the external diameter of the line wiring (and of the PE wiring,
if any) must not exceed the mounting range prescribed for the cable glands provided with the inverter.

•
Connect the neutral cable (normally blue) to the terminal labelled with the letter N.
Note:In the PVI-8.0/10.0/12.5-TL-OUTD models the connection of
neutral conductor (N) is optional and depends on the system
in which the inverter is installed. If the AC Grid to which the
inverter is connected includes single-phase devices or inverters
which could create an imbalance in the three-phase system, you
are recommended to use a star conguration (three-phase +N).
However, where the circuit only includes 3ph inverters you are
recommendedtouseadeltaconguration(neutralnotconnected).
In this case, the “3ph MOD” switch must be set to the Δ symbol

5.3. DC side connections
•
Check the polarity of each couple of cables that must be connected to the inverter input: mark the
cable corresponding to the positive pole so as to be able to distinguish it from the one corresponding
to the negative pole. In the case of several strings, observe the correspondence between the negative
and positive of each string.
•
Check the open circuit voltage of each pair of cables which must be connected in input to the inverter:
the value must in no case exceed the maximum input voltage of the inverter.
Warning! Voltage values which exceed the permitted levels may irreparably damage the unit. Any
consequential damage to the inverter is not covered by the warranty.
Warning! The maximum allowed current for each input connector is 20 A; for models equipped with input
fuses (sux “-FS”) this limit is set by the fuse current rating. Higher values may cause damage to the internal
fuses or to the fuses equipped on the unit.
Warning! The exposure to sunlight of photovoltaic panels generates dangerous voltages to the ends of the
cables of the PV generator. Before connecting cables from the PV generator to the DC input of the inverter you
MUST disconnect any external DC line or make the dimming of solar panels.
•
Crimp the Multicontact/Weidmüller MC4/WM4 quick t connector counterparts to the string cables or
to the cables wired to the string disconnect switches (external), paying attention to the voltage polarity
and to the connector / terminal, following the procedure below:
MOUNTING PROCEDURE FOR MULTICONTACT QUICK FIT CONNECTORS
•
Strip back the cable to which the connector
will be applied (after verifying it complies
with the connector limitations).
•
Apply the terminal to the conductor using
the special tweezers.
•
Fit the cable with the terminal inside the
connector until it snaps, indicating that
the terminal is securely tted inside the
connector.
•
Firmly tighten the cable gland in order
to prevent humidity inltration in the
connector, which may lead to increased
ground leakage.
Warning! Tightening the cable gland
is of crucial importance. Humidity
inltrations cause increased ground
leakage and may give rise to low
insulation resistance alarms signalled by
the inverter.

6. CONFIGURATION OF INPUT CHANNEL OPERATING MODE
The two input channels can be congured in two modes: independent mode and parallel mode.
The selection of the conguration of the input channels depends on the photovoltaic generator features and
on the power and current limitations of the inverter, as well as design choices and installation needs. Refer to
the system design documentation for information on the selection of the conguration of the inverter input
channels.
Warning! For the two channels to be used in independent mode, it is a NECESSARY condition that the
photovoltaic generator connected to each input has a maximum current and power below the channel’s
current and power limit.
Warning! For the two channels to be used in parallel mode, it is RECOMMENDED that the photovoltaic
generator connected to the two inputs has strings with the same number of modules in series and that all the
modules have the same installation conditions (inclination / orientation).
Refer to the technical data table in Appendix E to nd out the current and power limits of each input channel
for the various inverter models.
Warning! If the string’s current or power is above the current or power limit of the input channel to which it is
connected,thetwoinput channels MUST be congured in parallel.Thisconditionalsoconcernsthecasewhere
the photovoltaic generator comprises only one string with power above the inverter’s single input channel
power limit.
Note: The inverters are pre-set in the factory with INDEPENDENT input channels.
Warning! If the conditions shown above are not met, consult the photovoltaic system’s designer immediately.

7. SIGNALS TERMINAL BLOCKS
7.1. RS485 communication line connection
The RS485 communication port is the inverter’s communication port. AURORA uses a HALF-DUPLEX RS485
communication line made up of two transmission reception lines (+T/R and –T/R) and a reference communication
line (RTN): all three lines must be wired in a daisy-chain (“in-out”). It is advisable to use a twisted-pair screened
cable for the communication line: the screen must be earthed at only one point (typically near the monitoring
system) and continuity inside each element of the chain must be given to the screen. Refer to Appendix C.
The chain connection can be made without distinction by using the connector couples (one for in and one
for out – det. [Q]) or the terminal block (det. [R] or det. [S]). The connectors are identied by the printing
“RS485(A)”and“RS485(B)”: use of connector“A”as in and“B”as out is not compulsory (both connectors can be
used as in or out). Refer to Appendix A for the PIN-OUT of the RJ12 and RJ45 connectors.
The last inverter in the daisy chain must be “terminated” or the 120 Ohm communication line termination
resistance must be activated by switching the dip-switch (det. [T]).

The PVI-3.0/3.6/4.2/8.0/10.0/12.5-TL-OUTD models are equipped with a two-level terminal block allowing
one level to be used for line-in connection and the other for line-out connection. The terminal block is also
equipped with the LNK terminal for the PVI-3.0/3.6/4.2-TL-OUTD models and SCLD for the PVI-8.0/10.0/12.5-
TL-OUTD models allowing continuity to be given to the cable screen.
On the other hand the PVI-5000/6000-TL-OUTD models are equipped with a one-way terminal block (det. [R])
and therefore it is necessary to couple the line-in and line-out leads in the same clamp.
Note:Models PVI-3.0/3.6/4.2/5000/6000-TL-OUTD are equipped with a USB communication port, mounted on the right hand
side of the inverter. The USB communication port is a service port. This port exists for diagnostic use and the internal
controller’s rmware upgrade and is limited to service sta. Although drivers have been released (compatible with
Windows XP and Windows 7, for which no upgrades are envisaged) which permit this port to be also used for monitoring
(not recommended), the primary use remains strictly tied to debugging and updating the system. Power-One recommends
the use of the RS485 port for the continuous monitoring of system data.
With regard to the communication interface, the use of the dedicated Power-One PVI-RS485_RS232 or PVI-
USB-RS485_232 type converter is strongly recommended in order to prevent compatibility problems that can
sometimes be encountered with the standard models on the market.

7.2. Using the alarm terminal block
The alarm terminal block makes the contacts of a relay available to indicate congurable alarm conditions.
The alarm contact is available under normally open (N.O.) or normally closed (N.C.) operation compared to
the common terminal (C). The maximum rating for voltage / current that the relay can support is 230V / 1A.
