INSTALLATION AND CONFIGURATION MANUAL
FOR AURORA PHOTOVOLTAIC INVERTERS
Note about the use of the "Alarm" terminal block: the alarm terminal block makes the contacts of a relay available to indicate confi gurable
alarm conditions (for information on the possibility and confi guration modes of the "Alarm" function, see the user manual on the CD that comes in the
package). 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.

Note: The VDEW directive (envisaged in Germany) provides that a maximum imbalance of 4600W
for the phases is tolerated in a three-phase system. In the PVI-6000-OUTD-DE models, which have a
rated output power above this limit, the "Alarm" and "Remote" contacts will have a jumper fi tted in the
factory.
Anyway, in order to make the power limitation mechanism possible as required by the directive in force, further wiring of the inverters is
required and this can be carried out in two modes:
This way when several inverters are connected according to one of the diagrams as of above and one unit goes off / fails, a power output
limitation of 4600W is automatically set in all the units thus preventing a power imbalance between the phases.
