Precautions
● Ensure that the PE cable is securely connected. Otherwise, electric shocks may
● Do not connect the neutral wire to the enclosure as a PE cable. Otherwise,
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.

● 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.
● It is recommended that silica gel or paint be used around the ground terminal after the
PE cable is connected.
According to IEC 62109, to ensure the safe operation of the SUN2000 in the
case of ground cable damage or disconnection, properly connect the ground
cable of the SUN2000 and ensure that it meets at least one of the following
requirements before the grounding detection function becomes invalid:
– The PE cable is a single-core outdoor copper cable with a conductor
cross-sectional area of at least 10 mm
– Use cables with the same diameter as the AC output power cable and
ground the PE terminal on the AC connector and the ground screws on
the chassis.
In some countries and regions, the SUN2000 must have additional ground
cables. Use cables with the same diameter as the AC output power cable and
ground the PE terminal on the AC connector and the ground screws on the
chassis.
