5.2 Connecting the PE cable

Precautions
● Ensure that the PE cable is properly connected. If it is disconnected or loose,
● Do not connect the neutral wire to the enclosure as a PE cable. Otherwise,
Additional Information
The SUN2000 has the grounding detection function. This function detects whether
the SUN2000 is grounded properly before its startup, or whether the ground cable
is disconnected when the SUN2000 is running. This function works under limited
conditions. To ensure the safe operation of the SUN2000, ground the SUN2000
properly according to the connection requirements of the PGND cable. For some
power grid types, if the output side of the inverter is connected to an isolation
transformer, ensure that the inverter is properly grounded and set isolation
settings to Input not grounded, with a transformer to enable the inverter to run
properly.

● The PE point at the AC output port is used only as a PE equipotential point, and cannot
substitute for the PE point on the enclosure.
● After the ground cable is installed, it is recommended that the silica gel or paint be
applied to the ground terminal for protection.
According to IEC62109, to ensure safe application in case of the ground cable
is damaged or disconnected, connect the PE cable properly before the
