3.3.5.1 Aurora Inverter - Connection to a Single Photovoltaic Array
If the system has one single photovoltaic array and the current from it is less than
16Adc for the PVI-4.2 model or 10Adc for the PVI-3.0/3.6 models, and the power of
the array is below the limit for the single channel (see table in 8.1 paragaph), then the
array can be connected to one single input channel (IN1).
WARNING
: Before performing the following instructions, ALWAYS
perform the “AURORA ELECTRICAL DISCONNECT PROCEDURE”
described in section 3.3.1 of this manual.
To avoid possible misreadings in the insulation parameters, we recommend using an
electrical cable to short the 2 inputs of channel IN2 (shown in Fig. 12) that are not
connected to the photovoltaic array.
The cover of the Aurora inverter needs to be removed (Ref. Fig. 14 / screw pos. "A")
in order to gain access to the terminal block board.
After the cover is removed, short the pins marked as "- IN2" and "+ IN2" on the
terminal block "DC INPUTS". To connect the 2 pins, use the cable provided with the
unit as shown in Fig. 12.
After the above connections are completed, install the cover and tighten the screws
with a 1.5Nm (13.2 in-lbs) torque and perform the START-UP procedure in section 4.
