WARNING:
All power wires connecting AURORA must have a section of
at least 14 AWG (2.5mm
2
) and must be able to operate at temperature of at
least 90 °C.
We recommend using the following types of wires:
For connecting the panels: FG7 (0)R unipolar wire, or H07RNF wire with
sections 2.5; 4; or 6 mm
2
with an external diametre of max. 8,9mm.
For connecting to the grid: FG7(0)R tripolar wire with a section of 2.5
or 4 mm
2
with an external diameter of max 16,2mm.
At the bottom of the inverter, from left to right, (Fig. 11) there are:
¾
1 watertight cap. This cap can be replaced by the PG16,5 cable gland supplied
with the inverter to route the signal cable for RS485 serial link.
¾
1 Binder connector for connection to the grid
¾
1 pair of Multicontact connectors, for the connection of the PV array (IN1).
¾
2 watertight caps seal off the “IN2” inputs (only available on PVI-3600 models)

WARNING
: When making the electrical connections follow this exact
procedure to avoid exposure to dangerous voltages. Each step of the
procedure is explained in the following paragraphs.
To disconnect AURORA always open the AC breaker first and then
also the DC breaker prior to do any further operation and before
removing the AC and DC connections to the inverter.
