Note a: The value is valid only if the conductors of the PE cable and AC power cable use the same
material. If the materials are different, ensure that the conductor cross-sectional area of the PE
cable produces a conductance equivalent to that of the area S/2.
Note b: You are advised to use a soft cable to prevent poor terminal contact due to the bending
stress of the cable.

Installing the PE Cable

•
It is recommended that the PE cable
be connected to a nearby PE point.
Connect the PE points of all
SUN2000s in the same PV array to
ensure equipotential connections to PE
cables.
•
To enhance the corrosion resistance of
a ground terminal, you are advised to
apply silica gel or paint on it after
connecting the PE cable.
