4.2 Installing the Ground Cable

The ground point on the enclosure is preferred to connect to the PE cable for the SUN2000.
•
The ground point in the maintenance compartment is mainly used for connecting to the ground
cable included in the multi-core AC power cable. For details, see section " 4.4 Installing AC
Output Power Cables."
•
The ground cable must be secured.

It is recommended that the ground cable of the SUN2000 be connected to the nearest ground
point. For a system with multiple SUN2000s connected in parallel, connect the ground points of
all SUN2000s to ensure equipotential connections to ground cables.

To enhance the corrosion resistance of the PE terminal, apply silica gel or paint on it after
connecting the ground cable.
