Installation and operating manual
(PVI-3.8/4.6-I-OUTD Rev.: 1.5)
3.4.4
Installation of the AURORA inverter.
WARNING: The maximum DC input current to each of the two MPPT
circuits should not exceed 14Adc (PVI-4.6-I-OUTD), and 12.5Adc (PVI-3.8-
I-OUTD), under any conditions.
WARNING: Follow the procedure step-by-step in order to avoid damage to
things and injury to people.
Step 1: Disconnect the inverter from the AC grid by turning off the AC switch, "part
D" in Fig. 8. Also turn off the DC part by using the DC switch (integrated in -S models
or external).
Step 2: Remove the inverter front cover as described in paragraph 0. Connect the DC
cables to the inverter, carefully checking the correct polarity. For possible connection
types, refer to 3.4.5.
Step 3: Connect the AC cables to the terminal block, following the instructions laid
out in paragraph 3.4.6.
Step 4 (optional): Connect the signal cables to the specific terminal block. Replace
one of the capped holes present on the bottom of the inverter with a cable gland
(supplied) and use it to pass through the wires.
Step 5: Remove the cover from the photovoltaic panels
WARNING: Verify the polarity and the no-load voltage on the inverter
terminal block to ensure that the connection has been made correctly.
If the parameters fall within the range defined by the inverter's technical
specifications, reclose the inverter by replacing the cover and tightening the screws as
described in paragraph 0, then and proceed to section 4.
