5.3 Installing the AC Output Power Cable

Prerequisites
An AC switch must be installed on the AC side of the SUN2000L to ensure that the
SUN2000L can be safely disconnected from the power grid.
Do not connect any load between the SUN2000L and the AC switch.
Context
The SUN2000L can detect the grounding. This function is used to detect whether the
SUN2000L is properly grounded before starting it, or to detect whether the PE cable is
disconnected when the SUN2000L is working. This function is available only under limited
conditions. To ensure the safe operation of the SUN2000L, properly ground the SUN2000L 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 SUN2000L, you need to set
Grounding inspection to Disable after checking that the SUN2000L is properly grounded.
Then the SUN2000L can start normally. If you are not sure whether the SUN2000L 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.
