Ground fault/RCD protection

WARNING: In some cases, national and local regulations make it obligatory
to connect one of the DC input terminals to the system ground. Carefully
refer the national standard in order to ground the inverter input correctly.
A specific connector allows connecting one and only one of the two DC input
terminals (positive or negative) to the ground. A sophisticated ground protection
circuit constantly monitors the ground connection, deactivates the inverter in the event
that a ground fault is detected, and indicates the ground fault condition through a red
LED located on the front panel. The AURORA inverter is equipped with terminals for
the system ground conductors.
For further information about the grounding of terminals and protections, refer to
section 3.4.9
NOTE: For further details about disconnecting the AURORA inverters or
about the causes of malfunction, refer to paragraphs 0

Additional protective devices

The AURORA inverters are equipped with additional protections in order to ensure its
safe operation under any circumstances. These protections include:
continual monitoring of the grid voltage to guarantee that the voltage and
frequency values remain within the operational limits;
internal temperature control in order to limit power automatically, should it be
necessary to ensure that the unit does not overheat (heat sink temperature ≤70°C
[158°F]).
The numerous control devices create a redundant structure, ensuring the
absolute safety of its operation.
