Installing Ground Cables (Using the Ground Point on the Chassis Shell)

Installing AC Output Power Cables
4.3
• 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 4.3 "Installing AC
Output Power Cables."
1. The outdoor copper-core cable with a cross-sectional area of 16 mm
2
is recommended. The
ground cable must be secured.
2. It is recommended that 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.
3. To enhance the corrosion resistance of the ground terminal, apply silica gel or paint on it after
connecting the ground cable.
• If you connect a ground cable to the ground point on the chassis shell, you are recommended to
use a three-core outdoor copper-core cable with a cross-sectional area of 25 mm
2
as the AC
output power cable.
• If you connect a ground cable to the ground point in the maintenance compartment, you are
recommended to use a four-core outdoor copper-core cable with a cross-sectional area of 25
mm
2
as the AC output power cable.
• For more details about cable specifications, see the SUN2000-(50KTL, 50KTL-C1) User Manual.
• The AC OUTPUT 1 connector supports the cable with an outer diameter of 18 mm to 44 mm.
1. Never open the host panel of the SUN2000.
2. Before opening the SUN2000 maintenance compartment door, turn off the downstream AC output
switch and the two bottom DC switches.
