AURORA Inverter Typical Electrical Installations

WARNING: Before performing any operation on the Switch Box power
input, ALWAYS perform the "Switch Box CONNECTION and/or
DISCONNECTION PROCEDURE" as explained in section 3.3.1 of this
manual.
WARNING: THE INPUT CURRENT shall not exceed 16Adc for each input
channel (PVI-4.2) or 10Adc (PVI3.0/3.6)
WARNING: Before performing the procedures described below, ALWAYS
perform the "ELECTRICAL DISCONNECT PROCEDURE" as described in
section 3.4.1 of this manual.
Step 1: Disconnect from the AC Grid by turning Off the"AC Bipolar Switch" – Part
"D" in Fig. 9 "Electrical Connection Diagram".
Step 2: Remove the Switch Box cover and connect the DC cable to the terminal block
at pos "F" in "Fig.11 SB-02 –Switch Box"; carefully check the correct polarity of the
DC cable.
Step 3: Connect the AC cable by following the instructions in section 3.3.6,
"Electrical Connection to the AC Grid". Refer to Table CN-01 "AC Grid Connection"
Step 4: Open the inverter cover (4 screws in pos "b" of fig. 10) and connect the signal
cable (optional). Pass the cable inside the Switch Box through the input knockouts
(see pos "D" fig.11 "SB-01 – DC Switch Box Layout"), and then inside the inverter
through the cable gland placed in the upper side of the Switch Box; finally screw the
cable to the appropriate terminal block inside the inverter.
Step 5: Remove the cover from the photovoltaic panel or wait for the sun to irradiate
the panel
WARNING: Verify that the DC voltage in the Switch Box input (terminal
block pos. "F" Fig.11 "SB-02") has the correct polarity and is within the
operational range.
