3.3 Before Performing the Electrical Connections
WARNING: Before performing any operation on the Switch Box power
input or on the inverter ALWAYS PERFORM the disconnection procedure
as explained in sections 3.3.1 or 3.3.2 of this manual.
WARNING: The electrical connections must be connected only after the
Aurora inverter is firmly mounted to the wall.
WARNING: The connection of the Aurora inverter to the electrical
distribution grid must be performed by qualified and trained personnel and
only after receiving authorization from the utility that operates the grid.
WARNING: For a step-by-step description of the correct procedure, please
read - and closely follow - the instructions provided in this section (and its
subsections) and all safety warnings. Not complying with the instructions
that follow can lead to hazards and possible injury to personnel and/or
equipment damage.
WARNING:
All field wiring connected to signal circuits (WIND,
ALARM, REM & RS485) must be UL/CSA certified, rated 600 Vdc or
higher, and must be additionally protected by means of a non-metallic
conduit. Take care to provide means for securing all the above mentioned
wiring away from both AC side and DC side field wiring. Moreover, AC
side field wiring should be secured away from DC side field wiring.
WARNING: Always respect the nominal ratings of voltage and current
defined in section 8 (Technical Features) when designing your system.
Please observe these considerations in designing the photovoltaic system:
Maximum array DC voltage input to each MPPT circuit: 520 Vdc
under any condition.
Maximum array DC current input to each MPPT circuit: 14 Adc (PVI-
4.6-I-OUTD), 12.5A (PVI-3.8-I-OUTD).
WARNING: The electrical installation of the Aurora inverter must be
performed in accordance with the electrical standards prescribed by the
local regulations and by the National Electric Code (ANSI/NFPA 70
standard).
