Additional Information
The SUN2000 provides the grounding detection function. This function is used to
check whether the SUN2000 is properly grounded before the SUN2000 starts, or
check whether the ground cable is disconnected when the SUN2000 is running.
This function is only available under limited conditions. To ensure the safe
operation of the SUN2000, properly ground the SUN2000 according to the
connection requirements of the ground cable. For some power grid types, if the
output side of the SUN2000 is connected to an isolation transformer, ensure that
the SUN2000 is properly grounded and set Grounding inspection to Disable to
enable the SUN2000 to run properly. If you are not sure whether the SUN2000 is
connected to such a type of power grid, contact your dealer or Huawei technical
support for confirmation.
