5.3 Installing the AC Output Power Cable

Prerequisites
An AC switch must be installed on the AC side of the SUN2000 to ensure that the SUN2000
can be safely disconnected from the power grid.
Do not connect any load between the SUN2000 and the AC switch.
Context
The SUN2000 can detect the grounding. This function is used to detect whether the SUN2000
is properly grounded before starting it, or to detect whether the PE cable is disconnected when
the SUN2000 is working. This function is available only under limited conditions. To ensure
the safe operation of the SUN2000, properly ground the SUN2000 in strict accordance with
the connection requirements for PE cables. For certain types of power grids, if an isolation
transformer connects to the output side of the SUN2000, you need to set Grounding
inspection to Disable after checking that the SUN2000 is properly grounded. Then the
SUN2000 can start normally. If you are not sure whether the SUN2000 connects to such a
power grid, confirm it with your supplier or Huawei technical support.

 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.
 To enhance the corrosion resistance of a ground terminal, apply silica gel or paint around the
terminal after connecting the PE cable.
